FGA40N60UFDTU

Overview

The FGA40N60UFDTU is a Field Stop Insulated Gate Bipolar Transistor (IGBT) manufactured by Fairchild Semiconductor, now part of onsemi. It features a single N-channel configuration housed in a TO-3P (TO-247 variant) through-hole package with an isolated collector connection. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 600 V and a continuous collector current (Ic) of 40 A at 25°C. The device exhibits a typical saturation voltage (Vce(on)) of 3.0 V at 20 A and 15 V gate drive. Switching characteristics include a turn-on time of 15 ns and a fall time of 65 ns. Maximum power dissipation is rated at 160 W, with an operating junction temperature range from -55°C to +150°C.

Feature Summary

• Utilizes Field Stop technology for optimized conduction and switching performance.
• Features low saturation voltage to minimize conduction losses.
• Includes built-in fast recovery freewheeling diode for simplified circuit design.

Applications

• Motor control systems
• General purpose inverters
• Switching power supplies

Procurement Notes

Verify the manufacturer status carefully, as Fairchild Semiconductor's semiconductor business was acquired by onsemi. Confirm whether the specific batch contains original Fairchild markings or updated onsemi branding. Check for RoHS compliance status, as older stock may differ from current production runs. Ensure the TO-3P package dimensions match your thermal management requirements.

Selection Notes

Select this component when a robust 600 V IGBT with integrated diode is required for medium-power applications. The TO-3P package offers high thermal capacity suitable for heatsink mounting. Compare the 40 A continuous current rating against your peak load requirements. Consider the 3.0 V saturation voltage impact on overall system efficiency compared to lower-voltage-drop alternatives.

Part Context

This device belongs to the ultra-fast IGBT series designed for high-efficiency power conversion. It combines the high input impedance of a MOSFET with the low conduction loss of a bipolar transistor. The integration of the freewheeling diode reduces component count in bridge configurations. It is engineered for reliability in industrial and consumer power electronics environments.

Replacement Considerations

Direct substitutes include the FGH40N60SMD, which shares similar electrical ratings and package type. Other compatible options within the same family include the FGH40N60SFDTU. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement meets the same voltage and current specifications for safe operation.
