S-822T Description

Short technical summary and product information.

The SEMITEC S-822T is a Current Regulating Diode (CRD) in an SMD package, designed to maintain a constant current flow despite fluctuations in voltage. This component is suitable for applications requiring stable current, such as LED brightness stabilization, constant voltage circuits for Zener diodes, and sensor power supplies.

Key electrical specifications include a typical pinch-off current of 8.2 mA at 10V, a rated voltage of 50V, and an allowable reverse current of 50 mA. The operating temperature range for the S series is -40°C to 150°C, with a junction temperature of 150°C. The device is designed for surface mounting, offering convenience in modern PCB layouts.

CRDs simplify circuit design by requiring only one component to achieve constant current regulation, unlike multi-component solutions. This makes them ideal for space-constrained applications. The S series is specifically designed as a surface mount device, fitting seamlessly with other SMD components.
