Product details

The STD3PK50Z: The 70 W power dissipation ceiling at the case (Tc) means the DPAK package needs a good thermal connection to the PCB copper or a heatsink if the part runs near its current limit continuously.

The SuperMESH™ family includes other P-channel 500 V parts in DPAK, but gate charge, Rds(on), and drive voltage differ — a cross-reference search against the base product number STD3PK is the practical next step.

Gate drive and switching considerations

The STD3PK50Z requires a 10 V gate drive to achieve the specified 4 Ω Rds(on).

Frequently asked questions

What is the replacement for STD3PK50Z?

A form-fit-function cross-reference against other P-channel 500 V MOSFETs in the SuperMESH™ family with the base product number STD3PK is the practical approach — compare Rds(on), gate charge, and package before substituting.

What are the specifications of STD3PK50Z?

It comes in a DPAK (TO-252) surface-mount package.

What package does STD3PK50Z use?

The STD3PK50Z is supplied in a DPAK package, also known as TO-252-3 (DPak, 2 leads plus tab, SC-63), for surface-mount assembly.
