BAV170HYT116

Overview

The BAV170HYT116 is a low-leakage 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 reverse voltage of 80V and a maximum repetitive reverse voltage of 90V. The device supports an average rectified forward current of 0.215A and a peak forward surge current of 4.0A. Forward voltage is specified at 1.25V at 150mA, while reverse current is limited to 0.005µA at 75V. The junction temperature rating reaches 150°C, with a storage range from -65°C to 150°C.

Feature Summary

• Low leakage current characteristics suitable for general switching applications
• Common cathode dual diode configuration within a compact SOT-23 package
• High thermal stability with a maximum junction temperature of 150°C

Applications

• General purpose signal switching circuits
• Low leakage current requirements in electronic designs
• Surface mount assembly for compact consumer electronics

Procurement Notes

Verify the supply status carefully before procurement, as the BAV170HM variant is explicitly marked as not recommended for new designs. Confirm that the specific HY suffix version meets current project requirements. Ensure compatibility with standard SOT-23 footprint dimensions during PCB layout. Check RoHS compliance documentation for regulatory adherence. Validate that the component's thermal ratings align with the intended operating environment.

Selection Notes

Select this component when low reverse leakage is critical for circuit performance. The SOT-23 package offers space efficiency for dense layouts. Consider the 80V reverse voltage rating against peak circuit voltages. Evaluate the 0.215A continuous current limit for load requirements. Compare the 150°C junction temperature capability against ambient conditions. Ensure the common cathode topology matches the schematic design needs.

Part Context

This part belongs to ROHM's series of small-signal switching diodes designed for general-purpose applications. The BAV170HYT116 specifically addresses needs for low leakage in compact surface-mount designs. It shares the physical SSD3 package form factor with other variants in the family, facilitating standardized manufacturing processes. The product line focuses on reliability and performance in consumer and industrial electronics.

Replacement Considerations

The BAV170HY is listed as a similar level replacement with the same pinout and package. Verify that the HY variant maintains identical electrical parameters if substituting for the T116 tape-and-reel version. Confirm package dimensions remain consistent for board compatibility.
