BAV70-G3-08

Overview

The BAV70-G3-08 is a small signal switching diode manufactured by Vishay Semiconductors. It features a dual common cathode configuration housed in an SOT-23 surface-mount package. The device has a peak reverse voltage of 70 V and a continuous forward current rating of 350 mA. Electrical characteristics include a maximum reverse leakage current of 100 nA at 70 V, a typical capacitance of 1.5 pF at 0 V and 1 MHz, and a reverse recovery time of 6 ns. Power dissipation reaches 270 mW on an FR-4 board.

Feature Summary

• Fast switching dual diode with common cathode configuration
• Silicon epitaxial planar construction
• Molding compound meets UL 94 V-0 flammability rating
• Moisture sensitivity level 1

Applications

• General purpose switching applications
• High-speed digital circuits
• Signal demodulation
• Logic level shifting

Procurement Notes

Verify the specific ordering code suffix to confirm packaging format. The -08 designation indicates units are supplied on a 7-inch reel containing 3,000 pieces per 8 mm tape. Confirm that the commercial grade material categorization aligns with project requirements. Ensure compliance with RoHS directives as indicated by the G3 suffix before finalizing procurement orders.

Selection Notes

Select this component for designs requiring fast switching speeds and low capacitance in a compact footprint. The common cathode arrangement allows for efficient use of board space compared to discrete single diodes. Verify thermal management needs against the specified power dissipation limits on standard PCB footprints. Consider the operating temperature range when designing for extreme environmental conditions.

Part Context

This part belongs to the Vishay BAV70-G series of small signal switching diodes. The series offers various packaging options including 7-inch and 13-inch reels. The G3 suffix denotes green, commercial grade materials compliant with environmental standards. The component is distinct from automotive qualified variants which require separate verification.

Replacement Considerations

BAV70-G3-18 serves as a direct functional substitute with identical electrical specifications but differs in packaging quantity and reel size.
