S4025R +BOM

Compact TO-220 package suitable for PCB mounting

S4025R Information

Description

The S4025R is a Standard Recovery Silicon-Controlled Rectifier (SCR) from Littelfuse Inc. It's a type of thyristor that can be used as an electronic switch or rectifier in various applications. This device has a voltage rating of 400V and a current rating of 25A, making it suitable for medium-power switching and control circuits. The S4025R is packaged in a TO-220-3 package, which provides a compact and reliable form factor. It's designed for through-hole mounting and has a non-isolated tab that can be used for heat sinking or electrical connections. This SCR is commonly used in power supplies, motor controls, lighting systems, and other applications where high-voltage switching and control are required. Its standard recovery time makes it suitable for use in a wide range of circuits and systems.

Package

According to the product information, the package type of S4025R is TO-220-3, which is a through-hole type package.

Pinout
