BAV99T116

Overview

The BAV99T116 is a high-speed switching diode manufactured by ROHM Semiconductor, housed in an SSD3 (SOT-23) surface-mount package. It features two series-connected silicon elements with a center tap configuration. Key electrical specifications include a maximum DC reverse voltage of 75V and a peak repetitive reverse voltage of 85V. The device supports an average rectified forward current of 215mA and a non-repetitive peak forward surge current of 4A. It exhibits a typical reverse recovery time of 4ns and a maximum forward voltage drop of 1.25V at 150mA. The component operates within a junction temperature range up to 150°C and complies with RoHS standards.

Feature Summary

• High-speed switching capability with ultra-fast reverse recovery characteristics suitable for rapid signal processing.
• Dual-element internal structure configured as series-connected diodes with a common center tap terminal.
• Compact surface-mount design utilizing the SSD3 package format for efficient PCB space utilization.

Applications

• Ultra-high speed switching circuits
• Signal demodulation applications
• Clamping and protection circuits

Procurement Notes

Verify the specific ordering suffix T116 to confirm the reel packaging quantity and tape-and-reel format required for automated assembly processes. Ensure that the SSD3 package dimensions align with the designated footprint on the printed circuit board layout. Confirm compliance with relevant environmental directives such as RoHS if mandated by the final product regulations. Cross-reference the manufacturer's latest datasheet to validate any updates to mechanical drawings or marking codes before finalizing procurement orders.

Selection Notes

Select this component when a dual-diode configuration with a center tap is required in a minimal footprint. The BAV99T116 is appropriate for designs demanding fast switching speeds and low capacitance. Consider the 75V reverse voltage rating to ensure adequate margin for the operating environment. Compare against similar JEDEC standard variants like the BAV99HYT116 if higher reverse voltage ratings are necessary for the specific application constraints.

Part Context

This part belongs to the BAV99 family of small-signal switching diodes produced by ROHM Semiconductor. These devices are engineered for general-purpose high-speed switching tasks. The T116 suffix specifically denotes the taping format and packaging style. The family shares common electrical characteristics but may vary in reverse voltage ratings depending on the specific variant selected for the design.

Replacement Considerations

The BAV99HYT116 is documented as a similar level replacement with the same pinout and package. Verify that the increased reverse voltage rating of the HY variant does not conflict with existing design margins. Ensure that the physical dimensions remain identical to avoid rework during substitution.
