Product Description

DiodesZetex BAV21W-7-F is a silicon junction single switching diode designed for surface mount applications. It supports a maximum forward current of 400 mA and has a peak reverse repetitive voltage of 250 V. Housed in a compact SOD-123 package, this diode is optimized for automated PCB assembly lines and small form factor electronics applications. The device offers a low forward voltage drop of 1.25 V combined with a fast recovery time of 50 ns, making it suitable for switching and protection in industrial electronics, power supplies, and automotive circuits.

This diode operates reliably across a wide temperature range from -65°C up to 150°C, enabling use in harsh environments. Its peak non-repetitive forward surge current rating of 2.5 A provides robustness against transient surges. The compact physical dimensions of 3.85 mm length, 1.35 mm width, and 1.7 mm height permit high-density PCB layouts.

Typical use cases include electronic switching, signal or power rectification, and protection circuits in industrial equipment, consumer electronics, automotive electronics, and HVAC systems. The BAV21W series diode is known for consistent performance and reliability in demanding semiconductor applications.

Compact SOD-123 package helps integrate easily into surface mount device PCBs. High switching speed with 50 ns peak reverse recovery time enables efficient circuit response. Wide operating temperature supports reliability in rugged and industrial environments.

Forward voltage of 1.25 V reduces power losses in switching circuits. Peak surge and power dissipation ratings provide protection against electrical transient spikes.

Set includes one BAV21W-7-F diode in SOD-123 format supplied as tape packaging ready for automated insertion into manufacturing lines. Designed and manufactured in China, this component meets industry standard reliability for semiconductor discrete Switching Diodes.
