B5819WS Description

Short technical summary and product information.

The B5819WS from CJ is a Schottky barrier rectifier designed for low voltage and high frequency applications. It offers a maximum repetitive peak reverse voltage of 40V and a maximum RMS voltage of 28V.

This rectifier has a high current capability with a maximum average forward rectified current of 1A at 25°C. The forward voltage drop is low, with a typical value of 0.75V at 1A. It also features a high surge capability, rated for a peak forward surge current of 30A for 8.3ms.

The B5819WS is constructed with a metal silicon junction for majority carrier conduction and includes guarding for overvoltage protection. Its typical junction capacitance is 100pF. The operating and storage junction temperature range is from -55°C to +150°C.

Packaged in a SOD-323 surface mount case, this diode is suitable for applications where board space is limited. Terminals are solderable per MIL-STD-750, Method 2026.
