BAV99W-AQ

Diode Arrays Overview

The BAV99W-AQ is an automotive-grade general-purpose diode array manufactured by Diotec Semiconductor. It features a series connection of one pair of standard switching diodes housed in a compact SOT-323 (SC-70) surface-mount package. The device supports a maximum repetitive reverse voltage of 75 V and an average rectified forward current of 150 mA per diode. Key electrical characteristics include a maximum forward voltage of 1.25 V at 150 mA, a reverse leakage current of 1 µA at 75 V, and a fast reverse recovery time of 4 ns. It operates within a junction temperature range of -55°C to 150°C and holds AEC-Q101 qualification.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration, such as tape and reel or cut tape. Confirm that the component meets the required AEC-Q101 grade specifications for your target automotive application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when an automotive-certified dual diode array is required for high-speed switching tasks. The SOT-323 package is suitable for designs with strict spatial constraints. Ensure the system voltage does not exceed the 75 V reverse voltage rating and that the forward current remains within the 150 mA limit per diode to maintain reliable operation under specified thermal conditions.

Diode Arrays Part Context

This component belongs to the BAV99 series of high-speed switching diodes produced by Diotec Semiconductor. The 'AQ' suffix typically denotes automotive-grade qualification, distinguishing it from standard commercial variants. The series is designed for small-signal applications requiring fast response times and low capacitance in compact surface-mount packages.
