BM64374S-VA

Overview

The BM64374S-VA is a three-phase inverter Intelligent Power Module (IPM) manufactured by ROHM Semiconductor. It integrates IGBT power devices with gate drivers and protection circuits within a 25-PowerDIP package. The module supports a collector-emitter maximum voltage of 600 V and a continuous collector current of 15 A at 25°C. Key electrical parameters include a saturation voltage of 1.7 V, power dissipation of 41 W, and an isolation voltage of 1500 Vrms. Operating temperatures range from -25°C to +115°C.

Feature Summary

• Integrates high-side and low-side IGBTs with dedicated gate driver ICs for three-phase DC/AC inversion.
• Includes built-in protection mechanisms such as short-circuit current protection, under-voltage lockout, and thermal shutdown.
• Features open emitter configuration for the low-side IGBTs to facilitate external sensing.

Applications

• Industrial motor drives
• Servo amplifiers
• Inverter systems

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration. Confirm that the HSDIP-25 through-hole mounting style matches the target PCB layout. Ensure thermal management solutions accommodate the specified 41 W power dissipation and operating temperature limits. Check for any recent product change notices affecting pinouts or electrical characteristics.

Selection Notes

Select this IPM when a compact solution for three-phase control is required without discrete component complexity. The 600V rating suits standard industrial bus voltages. Consider the 15A current capacity against load requirements. The integrated protections simplify design compared to discrete IGBT stacks. Verify compatibility with 3.3V or 5V logic interfaces if applicable to the broader family.
