BAW156HMFHT116

Overview

The BAW156HMFHT116 is a low-leakage switching diode manufactured by ROHM Semiconductor, designed for automotive applications in compliance with AEC-Q101 standards. It features a dual anode common configuration housed in an SOT-23 (SSD3) surface-mount package. Key electrical specifications include a maximum reverse voltage of 80V and a peak repetitive reverse voltage of 100V. The device supports an average forward current of 215mA with a surge current capability of 4A. It exhibits a low reverse leakage current of 5nA at 75V and a forward voltage drop of 1.25V at 150mA. The typical reverse recovery time is 3 microseconds, making it suitable for general-purpose switching tasks.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Low reverse leakage current for efficient signal handling
• Dual anode common configuration for versatile circuit integration

Applications

• General-purpose switching circuits in automotive electronics
• Signal processing applications requiring low leakage
• Protection circuits within vehicle control modules

Procurement Notes

Verify the specific suffix HMFHT116 against official ROHM documentation to confirm packaging and tape-and-reel specifications. Confirm supply status as this variant may be designated as not recommended for new designs. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified in the datasheet before procurement.

Selection Notes

Select this component when automotive qualification is required alongside low leakage performance. Compare the 80V reverse voltage rating and 3us recovery time against circuit requirements. Consider the dual anode common topology for space-constrained designs. Verify that the SOT-23 package size fits the mechanical constraints of the target assembly.

Part Context

This part belongs to ROHM's BAW156 series of low-leakage switching diodes. The series is engineered for high reliability in harsh environments. The HMFHT116 designation indicates a specific taping and reel configuration for automated assembly. It shares core electrical characteristics with other variants in the family but differs in packaging and ordering suffixes.

Replacement Considerations

The BAS116HYFH is listed as a similar level replacement with the same pinout and package. Verify electrical parameter equivalence, particularly reverse voltage and leakage current, before substitution. Check if the alternative part maintains the required AEC-Q101 automotive qualification.
