BAV21 Description

Short technical summary and product information.

The BAV21 is a superfast recovery rectifier diode from On Semiconductor, designed for high-speed switching applications. It features a repetitive peak reverse voltage of 200V and an average forward rectified current of 250mA. The diode offers a fast reverse recovery time of 50ns, making it suitable for signal processing and high-speed switching circuits.

 

Electrical characteristics include a forward voltage of 1.0V at 100mA and 1.25V at 200mA, with low leakage current of 100nA at 25°C and 15µA at 100°C. Junction capacitance is typically 5pF, contributing to its high-speed performance. The device can handle peak forward surge currents up to 5A.

 

The diode is housed in a DO-35 (DO-204AH) axial lead package, rated for through-hole mounting. It has a maximum power dissipation of 500mW and operates over a junction temperature range of -50°C to 200°C. Thermal resistance junction-to-ambient is typically 300K/W. Weight is approximately 1.7g, and solder conditions are 260°C for 10 seconds.

 

The BAV21 is compliant with RoHS, REACH, and Conflict Minerals regulations. It is available in ammo pack packaging with a standard quantity of 5000 pieces. This diode is ideal for general-purpose rectification and high-speed switching in commercial and industrial applications.
