STGIPS20K60

Overview

The STGIPS20K60 is an intelligent power module featuring a 3-phase IGBT inverter bridge rated at 18 A and 600 V. It integrates proprietary control ICs for gate driving and freewheeling diodes within a fully isolated SDIP-25L package. The device supports 3.3 V, 5 V, and 15 V CMOS/TTL logic inputs with built-in hysteresis and pull resistors. Key electrical parameters include a maximum supply voltage of 450 V (500 V surge), continuous collector current of 18 A at 25°C, and short-circuit withstand time of 5 µs. Thermal resistance from junction to case is 2.4 °C/W for the IGBT and 5 °C/W for the diode. Isolation withstand voltage is 2500 Vrms/min.

Feature Summary

• Integrates short-circuit rugged trench gate field-stop IGBTs with negative temperature coefficient for safe paralleling.
• Includes internal bootstrap diode and interlocking function to prevent cross-conduction.
• Features smart shutdown capability with comparator-based fault protection against overtemperature and overcurrent.
• Provides undervoltage lockout for both low-voltage power supply and high-side bootstrap voltages.

Applications

• Three-phase inverters for motor drives
• Washing machines
• Refrigerators
• Air conditioners

Procurement Notes

Verify that the specific order code matches the required packaging configuration. Confirm that the application environment remains within the specified operating junction temperature range of -40 to 150 °C. Ensure the heatsink maintains the case temperature below 125 °C to guarantee reliable operation. Check for compliance with relevant environmental directives if applicable to the final product assembly.

Selection Notes

Select this module for compact AC motor drive designs requiring integrated protection features. The inclusion of TTL/CMOS compatible inputs allows direct connection to microcontrollers without external optocouplers. Consider the thermal resistance values when designing the cooling system for high switching frequencies. The short-circuit ruggedness simplifies the design of protection circuits for industrial and appliance applications.

Part Context

This component belongs to the SLLIMM (Small Low-Loss Intelligent Molded Module) family designed for low-power inverters. It combines advanced IGBT technology with dedicated control ICs to provide a complete solution for three-phase motor control. The module targets applications where space constraints and reliability are critical factors in the design process.

Replacement Considerations

Check datasheets for modules with similar voltage and current ratings, such as the STGIPS20C60 or STGIB20M60TS-L. Verify pin compatibility and isolation requirements before substitution. Note that newer series may offer improved thermal performance or different logic input thresholds.

FAQ

How does the smart shutdown function operate?

The smart shutdown function uses an internal comparator connected to the CIN pin. When triggered by a fault, it immediately turns off the output gate drivers regardless of the signal state at the SD/OD pin, ensuring rapid protection.

What is the purpose of the interlocking function?

The interlocking function prevents simultaneous conduction of the high-side and low-side switches in a half-bridge by forcing the outputs into a tri-state condition when conflicting logic signals are detected.

Can the STGIPS20K60 be driven directly by a microcontroller?

Yes, the module includes built-in pull-up/pull-down resistors and hysteresis on its logic inputs, allowing direct coupling to MCU terminals without the need for external optocouplers.
