BAW156HYFHT116

Overview

The BAW156HYFHT116 is a low-leakage switching diode manufactured by ROHM Semiconductor, housed in an SOT-23 (SSD3) surface-mount package. It features a dual common-anode configuration with a maximum repetitive peak reverse voltage of 80V and an average forward current rating of 215mA. The device exhibits a maximum reverse current of 5nA at 75V and a typical reverse recovery time of 3µs. Operating within a junction temperature range up to +150°C, it dissipates up to 250mW of power. This component is designed for general-purpose switching applications requiring high reliability.

Feature Summary

• Low leakage current characteristics suitable for sensitive signal paths
• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact SOT-23 surface-mount footprint for space-constrained designs

Applications

• General-purpose signal switching circuits
• Automotive electronic systems requiring AEC-Q101 compliance
• High-reliability consumer electronics protection

Procurement Notes

Verify the specific suffix 'T116' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 80V reverse voltage rating aligns with your circuit's peak inverse voltage requirements. Ensure compatibility with standard SOT-23 pick-and-place equipment. Check for any obsolescence notices or lifecycle status updates directly from ROHM before finalizing procurement plans.

Selection Notes

Select this component when low reverse leakage is critical to maintain signal integrity in switching applications. The common-anode configuration simplifies circuit topology for dual-diode needs. Consider the 3µs recovery time against faster alternatives if operating at significantly higher frequencies. The AEC-Q101 qualification makes it suitable for automotive environments where long-term stability under thermal stress is mandatory.

Part Context

This part belongs to ROHM's HY series of low-leakage switching diodes, which are engineered for enhanced performance over standard silicon rectifiers. The series is widely used in automotive and industrial sectors due to its robustness and small form factor. The BAW156 variant specifically offers a balanced trade-off between speed and leakage, distinguishing it from ultra-fast or high-current counterparts in the broader diode portfolio.

Replacement Considerations

The BAW156HYFH is listed as a similar level part with the same pinout and package. Verify if the non-T116 suffix meets your packaging requirements. No other direct substitutes are confirmed in the provided documentation.
