BAV99-HE3_A-18

Overview

The Vishay BAV99-HE3_A-18 is a small signal switching diode featuring dual diodes connected in series within an SOT-23 surface-mount package. It is AEC-Q101 qualified and RoHS-compliant. Key electrical parameters include a maximum repetitive peak reverse voltage of 70 V, a forward current of 350 mA, and a power dissipation of 270 mW on FR-4. The device exhibits a maximum reverse recovery time of 6 ns and a diode capacitance of 1.5 pF at 1 MHz.

Feature Summary

Dual diodes configured in series for high-speed switching applications
AEC-Q101 qualified for automotive reliability standards
RoHS-compliant construction with UL 94 V-0 flammability rating
Moisture sensitivity level 1 (MSL 1) for robust handling

Applications

High-speed switching circuits
Reverse polarity protection
General-purpose switching tasks

Procurement Notes

Verify the specific HE3_A suffix to confirm AEC-Q101 qualification status, as standard E3 variants lack this automotive certification. Ensure the -18 packaging code matches the required reel size for automated insertion processes. Cross-reference the datasheet revision date to validate current thermal resistance values against design requirements.

Selection Notes

Select this component when automotive-grade reliability is mandatory alongside fast switching performance. The series configuration allows for efficient voltage clamping or logic level shifting in compact layouts. Evaluate the 70 V reverse voltage limit against circuit peaks to ensure adequate safety margins during operation.

Part Context

This part belongs to the BAV99 series of small signal switching diodes manufactured by Vishay Semiconductors. It utilizes the SOT-23 plastic package, which is optimized for automatic insertion. The HE3_A designation indicates compliance with automotive quality standards, distinguishing it from commercial grade equivalents.
