BAV74

Overview

The onsemi BAV74 is a small signal switching diode featuring a dual common anode configuration housed in a surface-mount SOT-23 package. It supports a maximum continuous forward current of 200 mA and withstands a peak reverse repetitive voltage of 50 V. The device exhibits a fast recovery time of 4 ns with a typical forward voltage drop of 1 V. It operates within a temperature range of -55°C to +150°C and can handle a peak non-repetitive forward surge current of 2 A.

Feature Summary

• Dual common anode structure for efficient circuit design
• Fast switching capability with 4 ns recovery time
• High thermal stability operating up to 150°C

Applications

• General purpose signal switching
• Protection circuits
• Logic level shifting

Procurement Notes

Verify the specific ordering suffix, such as _NL, against official datasheets to confirm exact manufacturing lot details. Confirm RoHS compliance status through the manufacturer's material composition documents. Ensure the SOT-23 footprint matches the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact dual diode solution is required for low-voltage signal paths. The common anode topology simplifies wiring compared to discrete single diodes. Verify that the 200 mA current rating meets the application's peak load requirements without exceeding thermal limits.

Part Context

This part belongs to onsemi's general-purpose switching diode portfolio. It serves as a compact alternative to discrete diode arrangements in space-constrained designs. The SOT-23 package allows for automated surface-mount assembly processes.
