FSB50325T

Power Driver Modules Overview

The FSB50325T is a three-phase AC induction motor driver from the Motion SPM 5 Series. It integrates intelligent power module (IPM) technology within a 23-pin PDIP package designed for through-hole mounting. The device supports a maximum collector-emitter voltage of 250 V and delivers a peak IGBT collector current of 1.7 A. It operates with a typical switching frequency of 15 kHz and provides an isolation rating of 1500 Vrms. The unit functions reliably across a temperature range of -40 °C to +150 °C, with dimensions measuring 29.2 x 12.2 x 3.3 mm.

• Blower and fan drives
• Pump systems

Power Driver Modules Procurement Notes

Verify the specific suffix 'T' against official onsemi documentation to confirm tape-and-reel packaging versus tube configuration. Confirm the component status as End-of-Life or obsolete before design finalization. Ensure the selected variant matches the required thermal dissipation capabilities for the intended application environment.

Power Driver Modules Selection Notes

Select this component for applications requiring integrated three-phase motor control with simplified layout requirements. The IPM architecture reduces external component count compared to discrete solutions. Verify that the 250 V voltage rating and 1.7 A current limit align with the motor specifications. Consider the thermal performance limits when designing the heat sinking strategy.

Power Driver Modules Part Context

This part belongs to the Fairchild Semiconductor Motion SPM 5 Series, which was later absorbed into onsemi's portfolio. These modules are engineered for compact motor drive designs, combining power switching and control logic. The series targets cost-sensitive applications where board space is limited and reliability is critical.

Power Driver Modules Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify pin compatibility and electrical ratings if substituting with other SPM 5 variants or newer generations.
