Overview
The BT151S-650SJ is a medium power silicon-controlled rectifier (SCR) produced by WeEn Semiconductors. This component is designed for applications requiring high bidirectional blocking voltage and high thermal cycling performance. The BT151S-650SJ is housed in a TO-220AB package, making it suitable for various power switching applications. SCRs like the BT151S-650SJ behave similarly to transistors but have the unique ability to latch, remaining in conduction until the anode-cathode current drops below the holding current.
