FSB50550AT

Power Driver Modules Overview

The onsemi FSB50550AT is a Smart Power Module (IPM) from the Motion SPM 5 Series, designed for three-phase MOSFET inverter applications. It features a 500 V collector-emitter maximum voltage and a continuous collector current of 2 A at 25°C. The device utilizes silicon technology with an Rds(on) of 1 Ohm and supports a power dissipation of 14.5 W. Operating within a temperature range of -40°C to +150°C, it employs a 23-pin SPM5N-23 through-hole package.

Power Driver Modules Feature Summary

• Integrates three-phase MOSFET inverter bridge with control logic
• Provides high-voltage isolation between power and control circuits
• Supports direct drive for BLDC, PMSM, and AC induction motors

Power Driver Modules Applications

• Brushless DC (BLDC) motor drives
• Permanent Magnet Synchronous Motor (PMSM) control
• AC induction motor inverters

Power Driver Modules Procurement Notes

Verify the specific suffix 'AT' against the official onsemi datasheet to confirm pinout and internal configuration. Ensure the ordering part number matches the required package variant, as other series members like FSB50550BB or FSB50550AS may differ in current rating or mounting style. Cross-reference the manufacturer's latest documentation for any engineering change notices affecting this component.

Power Driver Modules Selection Notes

Select this module for low-power three-phase motor control requiring integrated protection and gate driving. The 2A current rating suits small appliances and precision motion systems. Consider the 23-pin through-hole package for ease of assembly in standard PCB layouts. Verify thermal management requirements given the 14.5W dissipation limit and operating temperature range.

Power Driver Modules Part Context

This component belongs to the onsemi Motion SPM 5 Series, which consolidates power switches and drivers into a single intelligent module. The series targets compact motor drive designs by reducing external component count. The FSB50550AT specifically addresses applications needing reliable three-phase inversion with built-in safety features.

Power Driver Modules Replacement Considerations

FSB50550BB: Offers 3A current rating in a 21-pin PowerDIP package. FSB50550AS: Surface mount version with similar electrical characteristics but different footprint.
