BAT54ST-7

Overview

The BAT54ST-7 is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated. It features a dual series configuration within an SOT523 package. The device supports a peak repetitive reverse voltage of 30 V and a continuous forward current of 200 mA. Electrical characteristics include a maximum forward voltage of 1,000 mV at 100 mA and a reverse leakage current of 2.0 µA at 25 V. Power dissipation is rated at 220 mW with a thermal resistance of 570 °C/W. Operating temperatures range from -65 °C to +150 °C.

Feature Summary

Dual series configuration for compact circuit integration
PN junction guard ring provides transient and ESD protection
Ultra-small SOT523 surface-mount package design
Low forward voltage drop and fast switching performance

Applications

DC-DC converter rectification
Power supply input protection
General purpose signal rectification in consumer electronics

Procurement Notes

Verify the specific ordering suffix matches the required packaging quantity. Confirm RoHS compliance status and lead-free plating requirements against project specifications. Ensure the component source is authorized to guarantee datasheet accuracy and traceability. Check for automotive-grade variants if environmental standards require higher reliability ratings.

Selection Notes

Select this component when space constraints necessitate the SOT523 footprint. Choose based on the requirement for low forward voltage and high-speed switching capabilities. Consider the 30 V reverse voltage rating for appropriate circuit protection levels. Evaluate the dual series topology against single diode alternatives for system complexity reduction.

Part Context

This part belongs to the BAT54T/AT/CT/ST family of surface-mount Schottky barrier diodes. The series utilizes silicon technology optimized for low conduction losses. It serves as a standard solution for small-signal rectification applications requiring minimal physical size and efficient thermal management in portable devices.
