FSB50250BS

Overview

The FSB50250BS is a Smart Power Module (SPM) from the Motion SPM® 5 V3 series, manufactured by onsemi. It integrates a three-phase inverter bridge with gate drivers and protection circuits into a single package. The module features a 500V voltage rating and an on-resistance of 6.5 ohms. It utilizes a 23-PowerDIP package for through-hole mounting.

Feature Summary

• Integrates three-phase MOSFET inverter bridge with intelligent gate drivers
• Includes built-in protection mechanisms such as overcurrent and thermal shutdown
• Designed for compact motor control applications requiring high power density

Applications

• Three-phase AC motor drives
• Brushless DC (BLDC) motor control systems
• Industrial servo drives

Procurement Notes

Verify the specific suffix 'BS' against the official datasheet to confirm pinout and feature set, as variations exist within the FSB50250 family. Check current availability status as some variants may be discontinued or subject to long lead times. Ensure compatibility with existing PCB footprints for the 23-PowerDIP package before ordering.

Selection Notes

Select this component for applications requiring a pre-validated three-phase inverter solution with integrated protection. Compare the 6.5 ohm on-resistance against system efficiency requirements. Verify that the 500V rating meets the bus voltage needs of the target motor drive application.

Part Context

This part belongs to the onsemi Motion SPM® 5 series, which combines power switches and drivers for motor control. The FSB50250 base number indicates a 500V, 1A class device. The 'BS' suffix denotes specific packaging or configuration details within this product line.

Replacement Considerations

Consult the official cross-reference list for direct replacements. Consider the FSB50250B or FSB50250AT if available, noting differences in current ratings and package configurations. Verify electrical parameters match before substitution.
