STMicroelectronics STEVAL-SCR002V1 Inrush Current Limiter

STMicroelectronics STEVAL-SCR002V1 Inrush Current Limiter is a simple and innovative AC-DC front-end circuit. The circuit allows the designer to perform an inrush current limitation in any converter with input rectifier bridge topologies. The STEVAL-SCR002V1 is based on a discrete control circuit made of one Z0110MN SMD triac and two STTH110A diodes. It offers a compact and non-insulated high voltage driver for the mains SCR.

Features

Two TN1605H-6T 16A – 600V Hi Tj SCRs in a TO-220 package, used to bypass the inrush resistor
