TK12A50D Description

Short technical summary and product information.

The Toshiba TK12A50D is an N-Channel Silicon MOSFET from the π-MOSⅦ series, suitable for switching regulator applications. This device features a low drain-source ON-resistance, with a typical value of 0.45 Ω at 10V VGS and 12A ID, and a maximum of 0.52 Ω. The gate threshold voltage (Vth) ranges from 2V to 4V under specific test conditions (VDS = 10 V, ID=1.0mA).

 

With a maximum drain-source voltage rating of 500V and a continuous drain current of 12A, the TK12A50D is designed for robust performance. It is packaged in a 3-pin TO-220NIS through-hole configuration. The device has undergone 100% avalanche testing, indicating reliability under specific overvoltage conditions. Minimum lot-to-lot variations contribute to robust device performance and reliable operation.
