BAV21-TAP

Overview

The BAV21-TAP is a high-voltage silicon epitaxial planar switching diode from Vishay General Semiconductor, housed in the DO-35 (DO-204AH) axial leaded package. It features a maximum repetitive peak reverse voltage of 250 V and a continuous forward current rating of 250 mA. The device exhibits a low reverse recovery time of 50 ns and a typical junction-to-ambient thermal resistance of 300 K/W. Operating temperature ranges extend from -55 °C to +175 °C, with storage capabilities up to 175 °C.

Feature Summary

• High-voltage capability with a 250 V repetitive peak reverse voltage rating
• Fast switching performance characterized by a 50 ns reverse recovery time
• Robust thermal management supporting operation up to a 175 °C junction temperature

Applications

• General-purpose signal switching circuits
• High-voltage rectification applications
• Electronic circuit protection designs

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging configuration. The TAP designation indicates an ammopack format containing ten thousand units per pack on 52 mm tape. Ensure compatibility with automated assembly equipment requirements for this specific reel or box quantity standard.

Selection Notes

Select this component when a fast-switching diode with a 250 V reverse voltage rating is required in an axial leaded package. Consider the 250 mA continuous forward current limit and the 500 mW power dissipation capacity during thermal design. Verify that the DO-35 footprint aligns with the target printed circuit board layout constraints.

Part Context

This part belongs to the BAV17 through BAV21 series of small-signal switching diodes manufactured by Vishay Semiconductors. All variants share identical physical dimensions and electrical characteristics except for their specific breakdown voltage ratings. The BAV21 represents the highest voltage option within this standardized family lineup.

Replacement Considerations

BAV21-TR serves as the primary alternative variant offering identical electrical specifications but utilizing a tape-and-reel packaging format instead of the ammopack configuration.
