Overview
The Vishay BAV19W-HE3_A-18 is a high-voltage small signal switching diode housed in an SOD-123 surface-mount package. It features a continuous reverse voltage of 100 V and a repetitive peak reverse voltage of 120 V. The device supports a DC forward current of 300 mA and an average rectified current of 200 mA, with a surge forward current capability of 1 A. Electrical characteristics include a maximum forward voltage of 1.25 V at 200 mA, a leakage current of 100 nA at 100 V, and a dynamic forward resistance of 5 Ω. Key performance metrics specify a diode capacitance of 0.5 pF at 1 MHz and a reverse recovery time of 50 ns.
Feature Summary
- Silicon epitaxial planar construction designed for general-purpose applications
- Qualified to the AEC-Q101 automotive reliability standard
- Molding compound meets UL 94 V-0 flammability rating
- Moisture sensitivity level rated as MSL 1
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- General-purpose high-voltage switching applications
- Signal processing and logic interface protection
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's document number 86372 and revision 1.1 against official Vishay records. Confirm that the specific ordering suffix matches the required packaging configuration and AEC-Q101 qualification status. Ensure all environmental compliance documentation aligns with project specifications before finalizing procurement.
Selection Notes
Select this component when a single-diode configuration with high-voltage blocking capabilities is required in a compact SOD-123 footprint. The HE3_A variant specifically addresses automotive reliability standards through its AEC-Q101 qualification. Evaluate thermal constraints carefully, as power dissipation ratings depend heavily on the available heatsinking and board layout conditions during operation.
Part Context
This part belongs to the BAV19W/BAV20W/BAV21W family of high-voltage small signal switching diodes manufactured by Vishay Semiconductors. All members share identical mechanical dimensions and packaging options but differ in their reverse voltage ratings. The BAV19W variant provides the lowest voltage threshold within this series, offering 100 V continuous reverse voltage.
Replacement Considerations
Direct substitutes within the same family include BAV20W-HE3_A-18 and BAV21W-HE3_A-18, which offer higher reverse voltage ratings while maintaining identical electrical and mechanical characteristics.
