Product Introduction

Overview

The STTH110A is a high-performance, ultrafast diode produced by STMicroelectronics. This diode is designed using ST's ultrafast high voltage planar technology, making it particularly suitable for various high-frequency applications. It is characterized by its fast recovery time, low forward voltage drop, and high reverse voltage rating, making it an excellent choice for free-wheeling, clamping, snubbering, and demagnetization in power circuits.
