PS11037

Overview

The PS11037 is a 600V, 50A Application Specific Intelligent Power Module (ASIPM) from Powerex Inc. It integrates IGBTs, freewheeling diodes, and gate drive circuitry in a compact package for small inverters up to 20kHz. Key electrical parameters include a collector-emitter saturation voltage of 2.9V at 50A, switching times of 0.6µS turn-on and 1.6µS turn-off, and an isolation voltage of 2500VAC. The module features built-in over-current, short-circuit, and under-voltage protection with fault output signaling.

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation before integration. Confirm that the operating temperature range and mounting torque specifications align with your thermal management design. Ensure the control supply voltages match your system's logic levels to prevent damage to the internal gate drive circuitry.

Selection Notes

Select this module for applications requiring a complete three-phase bridge solution with integrated protection. Consider the thermal resistance values when designing heatsinking solutions. Verify that the maximum PWM frequency requirements do not exceed the specified limits to ensure reliable operation and prevent excessive switching losses.
