BAV99LT116

Overview

The BAV99LT116 is a dual series-connected switching diode manufactured by ROHM Semiconductor in an SOT-23 (SSD3) surface-mount package. It features a reverse voltage of 75V, an average rectified forward current of 215mA, and a maximum peak repetitive reverse voltage of 85V. The device exhibits a fast reverse recovery time of 4ns and a typical forward voltage drop of 1.25V at 150mA. With a power dissipation rating of 250mW and a junction temperature range up to 150°C, it is designed for high-speed signal processing applications.

Feature Summary

• Dual internal elements configured in a series connection within a compact three-terminal SOT-23 package.
• High-speed switching capability characterized by a 4ns reverse recovery time for efficient signal handling.
• Robust thermal performance supporting operation at junction temperatures up to 150°C with 250mW power dissipation.

Applications

• General-purpose signal switching circuits
• High-speed digital logic interface protection
• Clamping and steering applications in consumer electronics

Procurement Notes

Verify the specific suffix LT116 against official ROHM documentation to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design, as variations exist within the BAV99 family. Cross-reference the datasheet for any recent supply status changes or recommended new designations.

Selection Notes

Select this component when a dual series-connected diode configuration is required in a minimal footprint. The BAV99LT116 offers a balance of speed and current handling suitable for low-power signal paths. Consider the 75V reverse voltage limit and 215mA continuous current rating to ensure adequate margins for the target application's operating conditions.

Part Context

This part belongs to the standard BAV99 switching diode family, widely recognized for general-purpose high-speed applications. ROHM manufactures this variant using silicon planar technology, ensuring reliability and consistency with industry-standard JEDEC parameters. The SSD3 package allows for automated surface-mount assembly, facilitating integration into dense printed circuit board layouts.

Replacement Considerations

The BAV99HYT116 serves as a direct replacement with identical pinout and package but offers an increased reverse voltage rating of 80V. Verify that the higher voltage specification does not impact circuit compatibility before substitution.
