Product details

The STP22NS25Z is an STMicroelectronics N-channel power MOSFET from the MESH OVERLAY™ series, built for through-hole mounting in a TO-220-3 package.

Obsolete — plan your BOM around surplus or a replacement

STMicroelectronics lists the STP22NS25Z as Obsolete. New designs should not target this part; existing BOM lines will need to source from independent distributors or surplus inventory.

Temperature range and package — built for the oven and the board

No moisture-sensitivity level is listed, but a TO-220 with an epoxy body typically runs MSL 1, so bake-before-reflow is not required unless the storage conditions were humid. Maximum power dissipation is 135 W at case temperature, which sets the heatsink sizing target.

Frequently asked questions

What are the specifications of STP22NS25Z?

The operating junction temperature range is -55°C to 150°C.

What is the replacement for STP22NS25Z?

For a replacement, search for a 250 V, 22 A N-channel MOSFET in a TO-220 package with similar on-resistance and gate charge — the closest pin-compatible alternative will share the same footprint and gate-drive voltage (10 V).

What is the cross reference for STP22NS25Z?

No official cross-reference part number is listed. The part is from the ST MESH OVERLAY™ series; a cross-reference search against the 250 V / 22 A / TO-220 / 150 mOhm parametric window is the practical approach.
