FSB50550AD

Power Driver Modules Overview

The FSB50550AD is a Smart Power Module (SPM) from the Motion SPM 5 Series, manufactured by Fairchild Semiconductor. It integrates a three-phase inverter bridge designed for AC induction motor control. The module features a maximum collector-emitter voltage of 500 V and a continuous collector current rating of 2 A. It utilizes a 23-pin PowerDIP package with dimensions of 29.2 x 12.2 x 3.3 mm. The device supports through-hole mounting and operates within a temperature range of -40 °C to +150 °C, with a typical switching frequency of 15 kHz.

Power Driver Modules Feature Summary

• Integrates a complete three-phase inverter bridge for simplified motor drive design
• Includes built-in protection mechanisms such as over-current and thermal shutdown
• Provides high-voltage isolation between power and control circuits

Power Driver Modules Applications

• AC induction motor drives
• Blower and fan control systems
• Pump motor applications

Power Driver Modules Procurement Notes

Verify the specific suffix 'AD' against official Fairchild or onsemi datasheets, as standard listings often reference variants like 'UTD' or 'AB'. Confirm pinout compatibility and thermal requirements before integration. Ensure the component source is authorized to avoid counterfeit risks associated with legacy semiconductor parts.

Power Driver Modules Selection Notes

Select this module for low-power three-phase motor applications requiring integrated gate drive and protection. Compare the 2 A current rating and 500 V blocking voltage against load requirements. Consider the 23-pin DIP footprint for PCB layout constraints and verify that the operating temperature range meets environmental specifications.

Power Driver Modules Part Context

This component belongs to the Motion SPM 5 Series, which consolidates power switches, drivers, and protection logic into a single package. Originally developed by Fairchild Semiconductor, the product line was transferred to onsemi following the company's acquisition. These modules are engineered to reduce design complexity and board space for motor control implementations.

Power Driver Modules Replacement Considerations

Direct substitutes include FSB50550UTD and FSB50550AB. Verify pin compatibility and electrical parameters when cross-referencing these variants. Note that manufacturer branding may differ due to corporate acquisitions.
