Product details

Sourcing is limited to the independent distribution channel — inventory that was produced before the EOL date and held in surplus stock.

600 V, 13.5 A, 500 mOhm — the switching MOSFET that defined a slot

These parameters position it for 400-500 W offline flyback converters, PFC stages, and mid-power DC-DC converters where a through-hole TO-220 package is acceptable. The maximum power dissipation is 160 W at case temperature, though practical dissipation depends heavily on heatsinking and airflow.

TO-220 package — mounting and thermal interface

The mounting type is through hole, intended for PCB mounting with the tab either soldered to a copper pad or bolted to an external heatsink.

Frequently asked questions

What is the replacement for STP14NK60Z?

No official replacement or successor order code is recorded from STMicroelectronics for the STP14NK60Z. For a pin-compatible alternative, you would need to evaluate other 600 V N-channel MOSFETs in TO-220 with similar on-resistance and gate charge characteristics from the same or alternate suppliers, but no manufacturer-validated cross-reference is available in the source data.
