BAV99/LF1R

Overview

The BAV99/LF1R is a dual switch diode manufactured by Nexperia, housed in an SOT-23 surface-mount package. It features a peak reverse repetitive voltage (Vrrm) of 100 V and a maximum continuous forward current (If) of 215 mA. The device exhibits a peak reverse recovery time (trr) of 4 ns and a peak non-repetitive forward surge current (Ifsm) of 4 A. Operating temperatures range from -65°C to 150°C, with a maximum forward voltage (Vf) of 1.25 V and a peak reverse current (Ir) of 500 nA.

Feature Summary

• Dual configuration within a compact three-pin SOT-23 surface-mount package
• High-speed switching capability characterized by a 4 ns peak reverse recovery time
• Automotive-grade reliability certified under the AEC-Q101 standard

Applications

• General-purpose high-speed switching circuits
• Clamping applications in signal processing paths
• Protection stages for automotive electronic systems

Procurement Notes

Verify the manufacturer designation carefully, as the BAV99 component is primarily produced by Nexperia rather than NXP USA Inc. Confirm that the specific suffix LF1R corresponds to the intended tape-and-reel packaging format. Ensure the part meets the required AEC-Q101 automotive qualification standards if deployed in vehicle electronics. Cross-reference the datasheet specifications against the actual component markings to prevent substitution errors during assembly.

Selection Notes

Select this component when a dual-diode solution is required in a minimal footprint SOT-23 package. The 100 V reverse voltage rating suits general low-voltage switching tasks. The 4 ns recovery time makes it suitable for high-frequency applications. Verify thermal limits for the specific operating environment, as the junction temperature range extends up to 150°C. Consider the 215 mA continuous current limit for load handling requirements.

Part Context

This component belongs to the BAV99 series of dual switch diodes. It utilizes a common cathode configuration within a single SOT-23 housing. The device is designed for surface-mount technology (SMT) assembly processes. It serves as a compact alternative to discrete dual-diode arrangements, saving board space in dense circuit designs.
