BAT54S_G

Overview

The BAT54S_G is a surface-mount Schottky barrier diode manufactured by onsemi, housed in a SOT-23 package. It features a dual series-connected configuration with a center tap, providing two independent rectifying elements within a single three-terminal device. The component supports a maximum repetitive peak reverse voltage of 30 V and a continuous forward current of 200 mA per diode. Key electrical characteristics include a low forward voltage drop and a fast peak reverse recovery time of 5 ns. It operates reliably across a junction temperature range from -55°C to 150°C.

Feature Summary

Dual series-connected diode structure with a common center tap for flexible circuit integration
Schottky technology ensures minimal conduction losses and low forward voltage drop
Fast switching capability with ultra-low reverse recovery time suitable for high-speed applications
Automotive-grade reliability certified under AEC-Q101 standards

Applications

Ultra-high-speed switching circuits
Voltage clamping and protection applications
Blocking diodes in power management systems

Procurement Notes

Verify the specific suffix G against official onsemi documentation to confirm exact marking and compliance details. Ensure the selected variant matches the required automotive qualification status if applicable to the design. Cross-reference the datasheet for precise thermal resistance values and recommended soldering profiles to maintain component integrity during assembly.

Selection Notes

Select this component when a compact dual-diode solution with a shared terminal is required. The SOT-23 package offers space efficiency for dense PCB layouts. Consider the 30 V reverse voltage rating and 200 mA current capacity to ensure adequate margins for the target application's electrical stress conditions.

Part Context

This part belongs to the BAT54 family of small-signal Schottky diodes produced by onsemi. The family includes various configurations such as common anode and common cathode arrangements. The BAT54S variant specifically utilizes a series connection topology, distinguishing it from parallel or independent dual-diode options within the same product line.
