Product details

75 V, 78 A N-channel MOSFET in DPAK — obsolete, last-time-buy sourcing

The STMicroelectronics STD78N75F4 is an N-channel power MOSFET built on the DeepGATE™ and STripFET™ technology platforms.

The STD78N75F4 carries an official product status of Obsolete.

The 75 V Vdss rating places this MOSFET in the 60 V to 80 V class, appropriate for 48 V bus systems, battery-powered equipment, and motor drives with moderate voltage transients. Input capacitance of 5015 pF at 25 V drain-source voltage influences switching losses and driver sizing.

Package and mounting — DPAK (TO-252-3)

The STD78N75F4 is supplied in a DPAK (TO-252-3) surface-mount package with two leads plus a tab (SC-63). The package supports Tape & Reel or Cut Tape shipping formats. The supplier device package is DPAK.

Frequently asked questions

What is the replacement for STD78N75F4?

For a pin-compatible alternative, evaluate other N-channel MOSFETs in the DPAK package with similar voltage and current ratings from STMicroelectronics or other manufacturers. Sourcing through independent distribution is the current channel for this obsolete part.
