BM64378S-VA

Overview

The BM64378S-VA is a 600V IGBT Intelligent Power Module (IPM) manufactured by ROHM Semiconductor. It integrates high-side and low-side IGBTs with gate drivers, bootstrap diodes, and protection circuits in an HSDIP-25 package. Key electrical parameters include a maximum collector-emitter voltage of 600V, a continuous collector current of 35A at 25°C, and a saturation voltage of 1.5V. The module supports a power dissipation of 69W and operates within a temperature range of -25°C to +115°C.

Feature Summary

• Integrates three-phase DC/AC inverter capabilities with built-in bootstrap diodes for simplified circuit design.
• Includes high-side gate drivers utilizing SOI process technology for high-voltage level shifting and control supply under-voltage lockout.
• Features low-side gate drivers with short-circuit current protection, thermal shutdown, and analog temperature output signals.

Applications

• Three-phase motor drives
• Industrial inverters
• Servo amplifiers

Procurement Notes

Verify the specific suffix VA against official datasheets to confirm pinout and functional compatibility. Check RoHS compliance status and long-term availability plans before finalizing procurement. Ensure thermal management solutions align with the 69W power dissipation rating. Confirm that the HSDIP-25 through-hole mounting style matches the target PCB layout requirements.

Selection Notes

Select this component for applications requiring robust three-phase inversion with integrated protection features. The 35A current rating suits medium-power industrial motors. Consider the 600V blocking voltage for standard AC line voltages. Evaluate the thermal performance relative to the ambient operating conditions and heatsinking capabilities available in the enclosure design.

Part Context

This IPM belongs to ROHM's standard series of intelligent power modules designed for general-purpose industrial applications. It is distinct from automotive-grade variants and is not recommended for use in vehicle-mounted equipment. The module consolidates discrete power devices and driver ICs into a single compact package to reduce board space and assembly complexity.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BM63364S-VA, BM63374S-VA, BM63564S-VA, BM63574S-VA, BM63764S-VA, and BM63964S-VA. Verify electrical specifications and pin compatibility before substitution.
