BAV70HYT116

Overview

The BAV70HYT116 is a high-speed switching diode manufactured by ROHM Semiconductor, housed in an SSD3 (SOT-23) surface-mount package. It features a common cathode configuration with three terminals. Key electrical specifications include a maximum reverse voltage of 80V and a peak repetitive reverse voltage of 90V. The device supports an average rectified forward current of 0.215A and a maximum forward surge current of 4A. It exhibits a low reverse current of 0.5µA at 80V and a typical reverse recovery time of 4ns at 10mA. The forward voltage is 1.25V at 150mA, with a junction temperature rating up to 150°C.

Feature Summary

• High-speed switching capability with a typical reverse recovery time of 4ns for efficient signal processing.
• Low reverse leakage current design suitable for applications requiring minimal power loss in off-states.
• Compact SOT-23 surface-mount package optimized for automated assembly and space-constrained PCB layouts.

Applications

• Ultra-high speed switching circuits
• General-purpose signal rectification
• Clamping and protection diodes in digital logic interfaces

Procurement Notes

Verify the specific ordering suffix T116 to confirm tape-and-reel packaging containing 3000 units per reel. Ensure the component meets RoHS compliance requirements for your manufacturing process. Confirm that the application does not involve automotive equipment, as this standard-grade product is explicitly not recommended for such use cases.

Selection Notes

Select this component when a common cathode dual-diode configuration is required within a small SOT-23 footprint. It is appropriate for designs prioritizing fast reverse recovery characteristics over high current handling. Consider thermal dissipation limits if operating near the maximum junction temperature or continuous current ratings.

Part Context

This part belongs to ROHM's BAV70 series of switching diodes, which are designed for general-purpose high-speed applications. The HY variant specifically denotes optimized performance characteristics compared to standard versions. It serves as a direct replacement for legacy parts like the BAV70HM, maintaining pinout compatibility while offering updated manufacturing standards.

Replacement Considerations

The BAV70HY is listed as a similar level part with the same pinout and package as the BAV70HM. Designers replacing the BAV70HM should verify that the active status of the BAV70HY aligns with long-term supply needs, as the HM variant is not recommended for new designs.
