2. Key Electrical Specifications

Rated Voltage (Collector-Emitter Voltage, V₍CE₎ₙₒₘ₋ₘₐₓ₎:
1200V DC (a common medium-voltage rating for industrial applications, compatible with 380V/480V AC grid systems, meeting the voltage requirements of most low-to-medium voltage industrial equipment such as motors, inverters, and UPS).
Rated Current (Continuous Collector Current, I₍C₎ₙₒₘ₋ₐₘ₈₅ₒC₎:
450A (continuous operating current under standard ambient temperature (85°C) and proper cooling; peak surge current (I₍Cₚₖ₋ₘₐₓ₎) reaches up to 900A for short durations (≤10ms), adapting to transient load peaks (e.g., motor startup, sudden load changes, or grid voltage fluctuations)).
Power Dissipation (Maximum, P₍ₗₒₛₛ₎ₘₐₓ₎:
Approximately 2.9kW (varies with switching frequency and junction temperature; requires a matched cooling solution—such as forced-air cooled heatsinks (for low-power scenarios) or water-cooled heatsinks (for high-power, long-term operation)—to maintain thermal balance and avoid overheating).
Switching Characteristics:
- Turn-on time (tₒₙ): ~0.5μs; Turn-off time (tₒₓₜ): ~0.7μs (fast switching speed, optimized for medium-frequency applications (2kHz–20kHz), reducing switching losses while ensuring stable commutation and low electromagnetic interference (EMI)).
- Switching losses (Eₒₙ/Eₒₓₜ): ~13mJ/21mJ (at rated voltage and current, minimizing energy waste during on/off transitions, enabling overall system efficiency of 97%+ in inverter applications).
Gate Drive Requirements:
- Gate voltage range: +15V (turn-on) / -10V (turn-off) (standard IGBT drive voltage, ensuring reliable switching and preventing false triggering caused by EMI or voltage noise).
- Gate current (peak): 15A–25A (sufficient drive current to ensure fast, complete switching of high-current IGBT chips, avoiding switching delay or incomplete turn-on/off losses).
Anti-Parallel Freewheeling Diode (FWD):
Integrated high-speed FWD with reverse recovery time (tᵣᵣ) ≤45ns, reducing reverse recovery losses and suppressing voltage spikes during current commutation—critical for enhancing the stability and lifespan of the power conversion system.

3. Performance & Functional Features

Advanced Trench-Gate Field-Stop (TFS) Chip Technology:
Adopts ABB’s proprietary TFS IGBT chip design, which minimizes on-resistance (R₍CE₎ₒₙ ~3.0mΩ at rated current) to reduce conduction losses. The chip’s optimized structure also improves voltage withstand capability and anti-surge performance, making it suitable for harsh industrial grid conditions (e.g., voltage sags, harmonics, or transient overvoltage).
High Power Density & Compact Design:
Through integrated packaging and miniaturized chip layout, the module delivers a 450A/1200V rating in a small form factor—reducing the installation space of power cabinets by ~15% compared to traditional discrete IGBT solutions. This compactness facilitates system integration for equipment with space constraints (e.g., industrial drive cabinets, mobile power units).
Comprehensive Protection Mechanisms:
- Overtemperature Protection (OTP): Built-in NTC (Negative Temperature Coefficient) thermistor to real-time monitor the IGBT junction temperature (Tⱼ); triggers an alarm when Tⱼ approaches 125°C and emergency shutdown when Tⱼ exceeds 150°C, preventing chip burnout due to overheating.
- Overcurrent Protection (OCP): Compatible with external current sensors (e.g., Hall-effect sensors or shunts) for fast overcurrent response (≤1μs), shielding the module from damage caused by short circuits, load overloads, or grid faults.
- Undervoltage Lockout (UVLO): Disables switching if the gate drive voltage drops below 12V (turn-on) or rises above -8V (turn-off), avoiding abnormal operation or module damage due to insufficient drive power.
Enhanced Environmental Adaptability:
- Isolation Voltage: ≥2500V AC (1 minute, between power terminals and baseplate), complying with IEC 60664 safety standards for industrial insulation—suitable for harsh environments with strict insulation requirements (e.g., dusty factories, high-humidity areas, or coastal renewable energy plants).
- Moisture & Dust Resistance: Uses hermetic ceramic-metal sealing technology to resist moisture (5%–95% relative humidity, non-condensing) and dust, ensuring stable operation in industrial sites with poor environmental conditions.

4. Operating & Storage Environment

Operating Temperature Range:
- Junction temperature (Tⱼ): -40°C to +150°C (long-term operation is recommended at Tⱼ ≤125°C to extend the module’s service life to 100,000+ hours).
- Ambient temperature (Tₐ): -25°C to +85°C (auxiliary cooling is required if Tₐ exceeds 60°C to maintain rated current and voltage performance; derate current by 2% per 1°C above 60°C if cooling is insufficient).
Vibration & Shock Resistance:
- Vibration: 5g (10Hz–2000Hz, IEC 60068-2-6 standard), adapting to mechanical vibrations in motor drive cabinets or mobile industrial equipment (e.g., mining machinery, mobile generators).
- Shock: 30g (11ms, half-sine wave, IEC 60068-2-27 standard), withstanding short-term impact during transportation, installation, or equipment maintenance.
Storage Conditions:
Temperature: -40°C to +85°C; Humidity: ≤85% relative humidity (store in a dry, dust-free environment with anti-corrosion packaging to prevent terminal oxidation, insulation degradation, or chip moisture damage).

5. Typical Application Fields

Industrial AC Drives: Used in medium-power motor speed control systems (e.g., 200kW–800kW pumps, fans, conveyors, or compressors in manufacturing, mining, or water treatment industries) to achieve precise speed regulation and energy savings.
Low-Medium Voltage Inverters: Applied in grid-connected inverters for small-to-medium renewable energy systems (e.g., 100kW–500kW solar PV inverters, small wind turbines) or industrial frequency converters for process control (e.g., textile machinery, printing equipment).
Uninterruptible Power Supplies (UPS): Suitable for medium-power UPS systems (50kVA–200kVA) in commercial buildings, data centers, or industrial auxiliary loads (e.g., control systems, precision instruments), ensuring continuous power supply during grid outages.
Welding & Induction Heating Equipment: Used in medium-power welding machines (e.g., arc welding, laser welding) and medium-frequency induction heating systems (e.g., metal heat treatment, plastic molding), leveraging its fast switching and high current handling capabilities.
Power Quality Equipment: Applied in low-voltage Active Power Filters (APF) or small Static Var Compensators (SVC) to suppress harmonic distortion and improve grid power quality for industrial workshops or commercial complexes.
