BAT54SHYT116

Overview

The BAT54SHYT116 is a Schottky barrier diode manufactured by ROHM Semiconductor, housed in an SSD3 (SOT-23) surface-mount package. It features a dual series connection configuration with three terminals. Key electrical specifications include a maximum repetitive reverse voltage of 30 V and an average rectified forward current of 0.2 A. The device supports a forward surge current of 0.6 A and exhibits a maximum forward voltage of 0.8 V at 0.1 A. Reverse current is limited to 0.002 mA at 25 V reverse bias. It operates within a junction temperature range up to 150 °C and is supplied in tape-and-reel packaging.

Feature Summary

• Ultra-small mold type construction utilizing the SOT-23 package for compact circuit board integration.
• Low forward voltage characteristic designed to minimize power loss during small current rectification applications.
• High reliability structure suitable for general-purpose electronic circuits.

Applications

• Small current rectification circuits
• General-purpose switching applications
• Signal processing stages requiring low voltage drop

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions remain within specified limits to maintain device integrity. Check for obsolescence notices as this family may have replacement recommendations. Validate package dimensions against PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring a compact Schottky diode with low forward voltage characteristics. The SOT-23 package suits space-constrained layouts. Verify that the 30 V reverse voltage rating meets circuit peak inverse voltage requirements. Consider the 0.2 A average current limit for load compatibility. Ensure thermal management aligns with the 150 °C maximum junction temperature specification.

Part Context

This part belongs to ROHM's Schottky barrier diode lineup, specifically optimized for low-voltage, high-efficiency rectification. The BAT54SH series utilizes silicon technology to achieve fast switching speeds and minimal power dissipation. The T116 suffix indicates specific tape-and-reel packaging parameters for automated assembly processes.

Replacement Considerations

BAT54SHY is listed as the active replacement for the discontinued BAT54SHM variant. Both share identical pinouts, packages, and electrical specifications. Designers transitioning from older batches should verify that the active version meets all original design constraints without modification.
