STH12N120K5-2 Description

Short technical summary and product information.

This STMicroelectronics STH12N120K5-2 is a single N-Channel MOSFET from the MOSFET (Metal Oxide) technology family. It is rated for a maximum drain-source voltage (Vdss) of 1200V and a continuous drain current of 12A (Tc). The device features a low on-resistance (Rds On) of 690mOhm at 6A and 10V, and a gate charge (Qg) of 44.2nC at 10V.

 

Designed for surface mounting, it comes in a TO-263-3, D²Pak (2 Leads + Tab), TO-263AB package, also known as H2Pak-2. The operating temperature range is -55°C to 150°C (TJ), with a maximum power dissipation of 250W (Tc). The gate-source voltage (Vgs) maximum is ±30V, and the gate threshold voltage (Vgs(th)) is 5V at 100µA.

 

This MOSFET is suitable for various power switching applications where high voltage and moderate current handling are required. Its surface mount package facilitates integration into compact electronic designs.
