BSM50GD120DN2BPSA1

Overview

The BSM50GD120DN2BPSA1 is a three-phase full-bridge IGBT power module manufactured by Infineon Technologies. It features an integrated fast free-wheeling diode and utilizes the EconoPACK 2 package with an insulated metal base plate. The device supports a collector-emitter voltage of 1200 V and a continuous collector current of 50 A at 25 °C, increasing to 72 A under specific conditions. Maximum ratings include a collector-gate voltage of 1200 V and a gate-emitter voltage limit of ±20 V. The module is designed for flange mounting and operates within a junction temperature range up to 150 °C.

Feature Summary

• Three-phase full-bridge configuration with built-in fast free-wheeling diodes
• EconoPACK 2 package design featuring an insulated metal base plate
• High thermal performance capability supporting operation up to 150 °C

Applications

• Industrial motor drives
• Uninterruptible power supplies (UPS)
• Induction heating systems

Procurement Notes

Verify the exact suffix against official Infineon documentation, as 'BPSA1' may indicate a specific packaging or revision variant distinct from standard 'DN2' listings. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the component matches the required pinout and thermal interface specifications for the target application before procurement.

Selection Notes

Select this module for applications requiring robust three-phase switching at 1200 V. Compare the 50 A continuous current rating against peak load requirements. Consider the EconoPACK 2 form factor for PCB integration or direct heatsink mounting. Evaluate thermal resistance parameters to ensure adequate cooling solutions are available for the expected power dissipation levels.

Part Context

This component belongs to the Infineon BSM series of IGBT modules, widely used in medium-power industrial applications. The BSM50GD120DN2 variant is a legacy part often referenced in older designs. The 'BPSA1' suffix likely denotes a specific tape-and-reel or bulk packaging option, though standard datasheets primarily list the DN2 designation. It serves as a core switching element in AC-DC and DC-AC conversion topologies.

Replacement Considerations

Direct replacements include the BSM50GD120DN2. Verify pin compatibility and thermal characteristics when substituting. Other Infineon EconoPACK 2 modules with similar voltage and current ratings may serve as functional alternatives if electrical parameters align.
