BAV21W-HE3_A-18

Overview

The Vishay BAV21W-HE3_A-18 is a high-voltage small signal switching diode in an SOD-123 surface-mount package. It features a repetitive peak reverse voltage of 250 V and a continuous forward current of 300 mA. The device exhibits a maximum reverse recovery time of 50 ns, a typical capacitance of 0.5 pF at 0 V, and a leakage current of 100 nA at 200 V. It operates within a temperature range of -55 °C to +150 °C and is AEC-Q101 qualified.

Feature Summary

Silicon epitaxial planar construction for general-purpose switching applications
Molding compound meets UL 94 V-0 flammability rating
Moisture sensitivity level 1 (MSL 1)
RoHS-compliant with AEC-Q101 qualification

Applications

General purpose switching circuits
Automotive electronics systems
High voltage signal processing

Procurement Notes

Verify the specific HE3_A suffix ensures AEC-Q101 automotive qualification rather than commercial grade. Confirm the -18 packaging code corresponds to 10,000 units per 13-inch reel. Validate that the component matches the exact Vishay document number 86372 specifications before integration into production designs.

Selection Notes

Select this component when a single-diode configuration requires a 250 V blocking capability with fast switching characteristics. The SOD-123 footprint offers space efficiency compared to larger packages. Ensure thermal management aligns with the specified junction-to-ambient resistance values under expected operating conditions.

Part Context

This part belongs to the BAV19W/BAV20W/BAV21W family of high-voltage silicon switching diodes manufactured by Vishay Semiconductors. The series provides scalable reverse voltage ratings from 100 V to 200 V across different model numbers while maintaining consistent electrical performance parameters and mechanical dimensions.

FAQ

What is the difference between the E3 and HE3_A ordering suffixes?

The E3 suffix indicates a RoHS-compliant commercial grade product, whereas the HE3_A suffix denotes a RoHS-compliant product that is also qualified to the AEC-Q101 automotive standard.
