BSM75GB120DN2HOSA1

Overview

The BSM75GB120DN2HOSA1 is a high-power IGBT module from Infineon's PrimePACK 3 family, designed for industrial motor drives and renewable energy applications. It features a 1200V blocking voltage and a continuous collector current of 75A at 25°C case temperature. The module utilizes Trench Field-Stop technology with an NPT (Non-Punch Through) structure to optimize switching losses and conduction characteristics. Key electrical parameters include a maximum DC link voltage of 1200V, a short-circuit withstand time of 10µs, and a typical turn-off energy of 48mJ at rated conditions. The device is housed in a robust plastic housing with a copper baseplate for efficient thermal management.

Feature Summary

• Integrated anti-parallel fast recovery diode for inductive load commutation
• Optimized thermal interface via direct bonded copper substrate
• Short-circuit ruggedness suitable for harsh industrial environments

Applications

• Industrial servo drives and frequency converters
• Uninterruptible power supplies (UPS)
• Solar inverters and wind turbine converters

Procurement Notes

Verify the complete part number including the suffix HOSA1 to ensure correct packaging and tape-and-reel configuration. Confirm that the requested units match the specific manufacturing lot requirements for your production line. Cross-reference the datasheet revision date to ensure compatibility with your design specifications. Ensure proper handling procedures are followed due to the sensitivity of the semiconductor junctions to electrostatic discharge during assembly.

Selection Notes

Select this module based on the required 1200V voltage rating and 75A current capacity for your specific thermal environment. Evaluate the gate-emitter threshold voltage and switching energy losses against your system efficiency targets. Consider the thermal resistance values provided in the datasheet when designing the heatsink interface. Ensure the gate drive circuitry can supply the necessary peak current to achieve the specified switching speeds without exceeding the safe operating area limits.

Part Context

This component belongs to Infineon's PrimePACK 3 series, which is engineered for high reliability and compact footprint in medium-power applications. The series is widely used in traction and industrial automation sectors where robust performance under varying thermal loads is critical. The PrimePACK 3 modules offer improved thermal cycling capability compared to previous generations, supporting longer operational lifetimes in demanding duty cycles.

Replacement Considerations

Direct replacements must match the 1200V/75A rating and PrimePACK 3 pinout. Verify equivalent switching energies and thermal resistances before substitution. Consult official cross-reference lists for confirmed compatible parts such as other Infineon variants within the same package family.
