SGH40N60UFDTU

Overview

The SGH40N60UFDTU is an Ultra-Fast IGBT manufactured by onsemi, originally developed by Fairchild Semiconductor. It features a TO-3PN package with a collector-emitter voltage (VCEO) of 600 V and a continuous collector current (IC) of 40 A at 25°C case temperature. The device incorporates a fast recovery diode with a typical reverse recovery time (trr) of 42 ns. Key electrical parameters include a saturation voltage (VCE(sat)) of 2.1 V at IC = 20 A, a maximum power dissipation (PD) of 160 W at 25°C, and a junction temperature range from -55°C to +150°C.

Feature Summary

Procurement Notes

Verify the component status carefully as this part originates from Fairchild Semiconductor prior to its acquisition by onsemi. Confirm that the specific ordering suffix matches the required package variant and ensure compliance with RoHS directives if applicable to the manufacturing batch. Cross-reference datasheet revisions to confirm electrical specifications align with current design requirements.

Selection Notes

Select this component for designs prioritizing low switching losses in high-frequency environments. Ensure thermal management strategies account for the specified thermal resistance values and derating curves. Verify that the gate drive circuitry supports the recommended ±15 V swing to achieve optimal turn-on and turn-off performance within the safe operating area limits.

Part Context

This device belongs to the UFD series of Insulated Gate Bipolar Transistors. It represents a legacy product line originally released by Fairchild Semiconductor, which has since been acquired by onsemi. The TO-3PN package provides robust mechanical mounting suitable for industrial power electronics applications requiring high current handling capabilities.

Replacement Considerations

Direct replacements may include other 600V 40A TO-3PN ultra-fast IGBTs from various manufacturers. Verify pinout compatibility and thermal characteristics when substituting. Check for updated datasheets from onsemi regarding equivalent modern alternatives in the FGH or SGH series.
