BAV21W

Overview

The BAV21W is a silicon epitaxial planar switching diode manufactured by ANBON SEMICONDUCTOR (INT'L) LIMITED. It features a surface-mount SOD-123 package with a peak repetitive reverse voltage of 200 V and a continuous forward current rating of 200 mA. The device supports a non-repetitive peak forward surge current of 2.5 A and has a maximum power dissipation of 250 mW. Electrical characteristics include a maximum reverse leakage current of 100 nA at rated DC blocking voltage, a total capacitance of 50 pF, and a maximum reverse recovery time of 5 ns.

Feature Summary

• Fast speed switching capability for general purpose applications.
• High conductance design utilizing silicon epitaxial planar chip technology.
• Surface mount construction in an SOD-123 package suitable for automated assembly.

Applications

• General purpose switching circuits
• High frequency rectification
• Clamping and protection applications

Procurement Notes

Verify the specific manufacturer datasheet to confirm RoHS compliance status and lead-free material declarations. Ensure the SOD-123 package dimensions match the target PCB footprint requirements. Confirm that the 200 mA continuous current rating aligns with the thermal management capabilities of the final assembly environment.

Selection Notes

Select this component when a high-conductance switching diode with fast recovery characteristics is required in a compact surface-mount form factor. The BAV21W offers a 200 V reverse voltage rating, distinguishing it from lower-voltage variants like the BAV19W. Consider the 250 mW power dissipation limit when designing for elevated ambient temperatures.

Part Context

This part belongs to the BAV19W through BAV21W series of switching diodes. These components share identical physical packaging and basic electrical structures but differ primarily in their reverse voltage ratings. The BAV21W represents the highest voltage variant within this specific family line, providing enhanced blocking capabilities compared to its counterparts.

Replacement Considerations

Cross-reference with Nexperia BAV21 or STMicroelectronics BAV21 for equivalent performance specifications. Verify pinout compatibility and package tolerance alignment before substituting in existing designs.
