FS75R12KE3B9BPSA1

Overview

The FS75R12KE3B9BPSA1 is a six-pack IGBT module manufactured by Infineon Technologies, designed for industrial power applications. It features a maximum collector-emitter voltage (VCEO) of 1.2 kV and a continuous collector current of 105 A at 25°C. The device exhibits a typical collector-emitter saturation voltage of 1.7 V and a maximum power dissipation of 355 W. Operating within a junction temperature range of -40°C to +125°C, it utilizes silicon technology and is housed in a tray package.

Feature Summary

• Six-pack topology integrating three half-bridge legs with integrated freewheeling diodes for efficient power conversion.
• Industrial-grade reliability with robust thermal performance capabilities under high-power switching conditions.
• Standard gate input characteristics compatible with common driver circuits for straightforward integration.

Applications

• Medium-power motor drives and servo systems
• Induction heating equipment
• Uninterruptible power supplies (UPS)
• Welding machines

Procurement Notes

Verify the specific suffix B9 against the official datasheet to confirm exact electrical tolerances and testing criteria. Ensure compatibility with existing cooling solutions given the 355 W dissipation rating. Confirm RoHS compliance status through the manufacturer's certificate before final procurement decisions.

Selection Notes

Select this module when a 1.2 kV rating and approximately 75 A nominal current are required in a compact six-pack configuration. Compare the 1.7 V saturation voltage against alternative models to optimize conduction losses. Evaluate the AG-ECONO2B package dimensions for mechanical fit within the target enclosure design constraints.

Part Context

This component belongs to the FS75R12 series of IGBT modules from Infineon. It shares the core electrical specifications with variants like FS75R12KE3BPSA1 but may differ in specific manufacturing batches or minor parameter distributions defined by the B9 suffix. It represents a standard solution for mid-range industrial inverter designs.

Replacement Considerations

FS75R12KE3BPSA1 is documented as a parameter-equivalent substitute. Verify pinout compatibility and thermal interface requirements before swapping. Other series members like FS75R12KT4B11BPSA1 offer different saturation voltages and should be evaluated based on specific efficiency needs.
