Overview
The Vishay BAV21W-HE3_A-08 is a high-voltage small signal switching diode housed in an SOD-123 case. It features a continuous reverse voltage of 200 V and a repetitive peak reverse voltage of 250 V. The device supports a DC forward current of 300 mA and a rectified average current of 200 mA. Electrical characteristics include a maximum reverse leakage current of 100 nA at 200 V, a typical reverse recovery time of 50 ns, and a diode capacitance of 0.5 pF at 0 V and 1 MHz. It operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Silicon epitaxial planar construction for general-purpose applications
- Qualified for automotive environments under AEC-Q101 standards
- 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 signal switching tasks
- High-voltage protection stages in consumer electronics
Procurement Notes
Verify the specific HE3_A suffix confirms AEC-Q101 qualification status during procurement. Confirm the -08 packaging code corresponds to the required 3,000 units per reel configuration on a 7-inch tape. Ensure the component version matches the Rev 1.1 datasheet specifications for electrical parameters.
Selection Notes
Select this component when automotive reliability and high-voltage handling are required in a compact surface-mount package. The BAV21W variant provides a 200 V reverse voltage rating, distinguishing it from lower-rated counterparts like the BAV19W or BAV20W. The HE3_A designation ensures compliance with automotive quality standards compared to commercial grade options.
Part Context
This part belongs to the Vishay BAV19W/BAV20W/BAV21W series of small signal switching diodes. These devices utilize silicon epitaxial planar technology and are designed for high-voltage applications. The series offers various packaging options and qualification levels to suit different industrial and automotive requirements.
Replacement Considerations
Direct substitutes within the same family include BAV21W-E3-08 (commercial grade) and BAV21W-HE3_A-18 (automotive grade, 13-inch reel). Cross-brand replacements require matching the 200 V reverse voltage, SOD-123 package, and 50 ns recovery time specifications.
