BAV21-TAP Description

Short technical summary and product information.

The BAV21-TAP is a high-voltage small signal switching diode from Vishay Semiconductors, part of the BAV17-BAV21 series. It is designed for general purpose switching applications requiring fast recovery and high voltage capability.

 

Key electrical specifications include a repetitive peak reverse voltage (V_RRM) of 250V, reverse voltage (V_R) of 200V, forward continuous current (I_F) of 250mA, and peak forward surge current (I_FSM) of 1A. The forward voltage is typically 1V at 100mA. Reverse recovery time (trr) is 50ns, making it suitable for high-speed switching. Junction capacitance is 1.5pF at 0V.

 

The diode is housed in a DO-35 (DO-204AH) axial leaded package, suitable for through-hole mounting. It has an operating junction temperature range up to 175°C and a power dissipation of 500mW. The device is RoHS3 compliant and has an MSL of 1 (unlimited).

 

Typical applications include general purpose switching, high voltage rectification in low power circuits, and protection circuits. The BAV21-TAP is available in tape and reel or ammopack packaging options.
