BAV70T-7-F

Overview

The BAV70T-7-F is a dual surface-mount switching diode in an SOT523 package. It features a peak repetitive reverse voltage of 85 V and a forward continuous current rating of 75 mA for the double diode configuration. The device exhibits a maximum reverse recovery time of 4.0 ns and a typical total capacitance of 0.81 pF at 1.0 MHz. Power dissipation is rated at 150 mW with a thermal resistance junction-to-ambient of 833 °C/W. Operating and storage temperatures range from -55°C to +150°C.

Feature Summary

• Ultra-small surface-mount package designed for automatic insertion
• Fast switching speed suitable for general-purpose applications
• High conductance characteristics

Applications

• General-purpose switching circuits
• Signal processing applications requiring fast response
• Automotive electronics (specifically BAV99TQ variant)

Procurement Notes

Verify component authenticity by checking the marking code 'JJ' on the SOT523 package against official Diodes Incorporated documentation. Confirm RoHS compliance and lead-free status through supplier certificates. Ensure the ordering suffix '-7-F' corresponds to the standard 3000-unit tape and reel carrier format specified in the datasheet.

Selection Notes

Select this component when space constraints require an ultra-small SOT523 footprint. Choose based on the 85 V reverse voltage limit and 75 mA continuous current capability. Consider the 4.0 ns reverse recovery time for high-speed signal applications. Verify thermal management requirements against the 150 mW power dissipation rating.

Part Context

This part belongs to the BAS16T/BAW56T/BAV70T/BAV99T family of surface-mount fast switching diodes manufactured by Diodes Incorporated. All members share the same SOT523 mechanical outline but differ in electrical specifications such as breakdown voltage and forward current ratings.

Replacement Considerations

Datasheets list BAV70DW-7-F, BAV99T-7-F, and MMBD7000HS-7-F as similar components within the manufacturer's portfolio. Verify pinout compatibility and specific electrical limits before substitution.
