BAS21W

Single Diodes Overview

The BAS21W is a high-voltage switching diode manufactured by Taiwan Semiconductor Corporation. It is encapsulated in a small surface-mounted device plastic package, specifically the SOT-323-3 (SC-70) form factor. The component features a single diode configuration with a maximum repetitive peak reverse voltage of 250 V and an average forward current rating of 100 mA. Key electrical characteristics include a maximum reverse recovery time of 50 ns, a maximum reverse leakage current of 100 nA, and a maximum forward voltage drop of 1.25 V at specified conditions. The device operates within a junction temperature range of -55 °C to +150 °C and has a power dissipation rating of 200 mW.

Single Diodes Procurement Notes

Verify the specific suffix 'RVG' against the manufacturer's official datasheet to confirm packaging details and marking codes. Ensure the selected variant matches the required SOT-323-3 footprint and lead-free compliance standards. Cross-reference the part number with the latest revision history to avoid obsolete stock or pinout discrepancies during procurement.

Single Diodes Selection Notes

Select this component when a single high-voltage switching diode is required in a minimal footprint. The 250 V reverse voltage rating makes it suitable for higher voltage signal paths compared to standard low-voltage diodes. Consider the 50 ns reverse recovery time for frequency constraints and ensure the thermal management supports the 200 mW power dissipation limit in the intended enclosure.

Single Diodes Part Context

This component belongs to the BAS21W series of high-voltage switching diodes. It is electrically comparable to other industry-standard small-signal switching diodes but offers specific performance metrics defined by Taiwan Semiconductor. The series includes variants such as dual common anode and series configurations, providing flexibility for different circuit topologies while maintaining consistent package dimensions.

Single Diodes Replacement Considerations

Compatible substitutes include the Nexperia BAS21W and Diodes Incorporated BAS21W-7-F. Verify that alternative sources maintain the same SOT-323-3 package and meet the 250 V reverse voltage and 50 ns recovery time specifications before integration.
