What are the key specifications of the B5819WS?

It features a 40V peak repetitive reverse voltage, 1A average forward current, and a forward voltage drop of 0.60V at 1A.

What is the B5819WS used for?

It is suitable for general-purpose applications, including power rectification, signal switching, and protection circuits.

What should engineers review before using the B5819WS?

Engineers should review the thermal resistance (400 °C/W for SOD-323) and ensure the operating junction temperature does not exceed 125 °C.

What should sourcing teams check before buying B5819WS?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: low; readiness: easy.

What is the pinout of B5819WS?

Use the B5819WS datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about B5819WS pinout to locate pins, power rails, and interface signals before layout.
