BAV70T

Overview

The BAV70T is a small-signal switching diode manufactured by onsemi, housed in an SOT-23 surface-mount package. It features a dual common cathode configuration with a peak reverse voltage of 75 V and a maximum forward current of 215 mA. The device exhibits a fast recovery time of 6 ns and a low forward voltage of 1.25 V at 50 mA. Operating temperatures range from -55 °C to +150 °C, with a power dissipation rating of 300 mW.

Feature Summary

• Dual common cathode architecture for efficient signal routing
• Fast switching capability with 6 ns recovery time
• High thermal stability supporting extended temperature ranges

Applications

• General-purpose signal switching circuits
• Protection against reverse polarity in electronic systems

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as BAV70T1G or BAV70HY may indicate different electrical tolerances or packaging formats. Confirm RoHS compliance status and ensure the selected variant matches the required reverse voltage and current ratings for the target application environment.

Selection Notes

Select this component for designs requiring compact dual-diode solutions in limited board space. The SOT-23 package facilitates automated assembly processes. Ensure the circuit design accounts for the 75 V reverse voltage limit and the 215 mA average forward current constraint to maintain reliable operation under expected load conditions.
