Overview
The BAV21W-HE3-18 is a high-voltage small signal switching diode from Vishay Semiconductors, utilizing silicon epitaxial planar technology in an SOD-123 surface-mount package. It features a repetitive peak reverse voltage of 250 V and a continuous reverse voltage of 200 V. The device supports a DC forward current of 250 mA and a surge forward current of 1 A. Electrical characteristics include a maximum reverse recovery time of 50 ns, a typical leakage current of 100 nA at 200 V, and a forward voltage of up to 1.25 V at 200 mA. It operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- High-voltage capability with a 250 V repetitive peak reverse voltage rating for robust circuit protection
- Fast switching performance characterized by a 50 ns maximum reverse recovery time
- Automotive-grade reliability through AEC-Q101 qualification for enhanced durability
- RoHS-compliant construction using silicon epitaxial planar technology
Applications
- General purpose switching circuits requiring high reverse voltage tolerance
- Industrial equipment signal processing and isolation
- Automotive electronics systems demanding AEC-Q101 qualified components
Procurement Notes
Verify the specific HE3 suffix indicates AEC-Q101 automotive qualification rather than standard commercial grade. Confirm the -18 packaging code corresponds to the required reel quantity and tape specifications for your assembly line. Ensure the component meets RoHS compliance standards for your region. Cross-reference the datasheet revision date to confirm the electrical parameters match your design requirements.
Selection Notes
Select this component when a single diode requires a 250 V peak reverse voltage rating in a compact SOD-123 footprint. It is suitable for applications needing fast switching speeds around 50 ns and moderate forward current handling up to 250 mA. Consider the AEC-Q101 qualification if the application involves automotive environments or requires higher reliability standards compared to commercial-grade alternatives.
Part Context
This part belongs to the BAV19W/BAV20W/BAV21W series of small signal switching diodes. The series offers varying reverse voltage ratings, with the BAV21W providing the highest voltage tolerance among the three. All variants share similar physical dimensions and thermal characteristics but differ in their breakdown voltage specifications to suit different circuit protection needs.
Replacement Considerations
Direct substitutes within the same Vishay series include BAV19W-HE3-18 and BAV20W-HE3-18, though these offer lower reverse voltage ratings of 120 V and 200 V respectively. Verify that any replacement maintains the required 250 V peak reverse voltage and AEC-Q101 qualification status.
