FGA50N60LS

Overview

The FGA50N60LS is an N-Channel Insulated Gate Bipolar Transistor (IGBT) from the LS series, originally manufactured by Fairchild Semiconductor and now managed by onsemi. It features a collector-emitter voltage of 600V and a continuous collector current of 50A at 100°C case temperature. The device exhibits a low saturation voltage of 1.6V at 50A and 15V gate drive. It supports a short circuit withstand time of 10µs at 100°C. Key electrical parameters include a maximum gate-emitter voltage of ±20V, a threshold voltage range of 3.5V to 7.5V, and a total gate charge of 167nTyp at 300V/50A. Thermal resistance junction-to-case is 0.52°C/W.

Feature Summary

• Short circuit ruggedness rated for 10 µs operation at elevated temperatures
• Optimized for medium frequency switching applications between 1kHz and 5kHz
• Low saturation voltage characteristics to minimize conduction losses
• High input impedance suitable for standard gate drive circuits

Applications

• Switched reluctance motor controls
• AC & DC motor controls
• General purpose inverters
• Robotics systems
• Servo controls

Procurement Notes

Verify component authenticity through authorized distribution channels due to historical manufacturer consolidation. Confirm package integrity upon receipt as the TO-3P housing requires specific mounting torque specifications. Ensure thermal interface material compatibility with the metal tab for optimal heat dissipation performance in final assembly.

Selection Notes

Select this component for designs requiring robust short-circuit tolerance and moderate switching speeds. Evaluate thermal management requirements based on the specified junction-to-case resistance. Verify that the system operating frequency aligns with the optimized 1kHz to 5kHz range for best efficiency balance between conduction and switching losses.

Part Context

This IGBT belongs to the LS series designed for medium-frequency power conversion. Originally released by Fairchild Semiconductor, the product line has been integrated into onsemi's portfolio following corporate acquisition. The datasheet revision indicates it is a finalized production specification document covering electrical and thermal limits for engineering design reference.

Replacement Considerations

Check for direct cross-reference part numbers within the onsemi catalog that maintain identical pinout and electrical ratings. Verify that any substitute device meets or exceeds the 10µs short circuit rating and 600V blocking voltage requirement for safe system integration.
