FSB50250A

Overview

The FSB50250A is a three-phase Intelligent Power Module (IPM) from the Motion SPM® 5 series, manufactured by onsemi. It integrates MOSFETs with gate drivers in a single package. The module supports a collector-emitter voltage of 500 V and a continuous current of 1.2 A. It features 1500Vrms isolation between power and control circuits. The component utilizes a 23-PowerDIP package designed for through-hole mounting.

Feature Summary

• Integrates three-phase MOSFETs and gate drive circuitry within a single compact module
• Provides high-voltage isolation to protect low-voltage control logic
• Designed for simplified motor control applications requiring integrated protection

Applications

• AC induction motor drives
• Brushless DC (BLDC) motor control systems
• Fan and pump speed control applications

Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor's semiconductor division was acquired by onsemi. Ensure the part number suffix matches the required package variant. Confirm RoHS compliance status and check for any Product Change Notifications regarding marking or assembly updates before finalizing procurement specifications.

Selection Notes

Select this IPM for applications requiring integrated three-phase switching with minimal external component count. The 500V rating suits standard industrial motor voltages. Consider the 1.2A current limit when sizing for specific load requirements. Verify that the 23-pin DIP footprint aligns with the target PCB layout constraints.

Part Context

This component belongs to the SPM 5 family of intelligent power modules. These modules are engineered to reduce design complexity by combining power switches and drivers. The FSB50250A specifically targets small to medium-sized motor control designs where space efficiency and integration are prioritized over high-power throughput.

Replacement Considerations

FSB50250AT serves as a compatible alternative within the same series. Verify pinout compatibility and thermal characteristics before substitution. Note that the base model may have different packaging or marking variations compared to the AT suffix version.
