BAV99L

Overview

The BAV99L is a small signal switching diode manufactured by Diotec Semiconductor, housed in an SOT-23 (TO-236) surface-mount package. It features a dual series-connected configuration with a maximum repetitive peak reverse voltage of 100 V and a maximum average forward current of 215 mA per diode. The device exhibits a reverse recovery time of less than 4 ns and a junction capacitance of less than 2 pF at 1 MHz. Operating temperatures range from -55°C to +150°C, with a power dissipation rating of 350 mW.

Feature Summary

• High-speed switching capability with extremely low reverse recovery time
• Low leakage current for efficient signal processing
• Enhanced reverse voltage tolerance up to 100 V

Applications

• High-speed signal processing circuits
• Reverse polarity protection
• General-purpose rectifying applications

Procurement Notes

Verify the specific ordering suffix to confirm the quality grade. The absence of a suffix indicates industrial grade, while the -AQ suffix denotes AEC-Q101 qualification. Confirm compliance requirements such as RoHS and REACH status directly with the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when a high reverse voltage rating of 100 V is required alongside fast switching speeds. It serves as a suitable alternative to standard BAV99 variants where higher breakdown voltage is necessary. Ensure the thermal resistance and power dissipation limits are compatible with the intended ambient temperature conditions.

Part Context

This part belongs to the BAV99 series of SMD small signal diodes produced by Diotec Semiconductor. The series includes variants like the BAV99 and BAV199, differentiated primarily by their reverse voltage ratings and leakage characteristics. All share similar packaging and basic switching performance profiles.
