BAT54C

Overview

The BAT54C is a dual Schottky barrier diode in an SOT-23 package with a common cathode configuration. It features a maximum repetitive reverse voltage of 30 V and an average rectified forward current of 200 mA. The device supports a non-repetitive peak forward surge current of 600 mA and dissipates up to 290 mW of power. Electrical characteristics include a maximum reverse leakage current of 2 µA at 25 V, a total capacitance of 10 pF at 1 MHz, and a reverse recovery time of 5.0 ns.

Feature Summary

Dual Schottky barrier diodes configured as common cathode for high-speed switching
Extremely low forward voltage reduces conduction loss
Miniature surface mount package suitable for space-limited applications

Applications

High speed switching circuits
Circuit protection
Voltage clamping

Procurement Notes

Verify the specific part number against ON Semiconductor's official ordering database due to historical Fairchild integration changes where underscores were replaced by dashes. Confirm that the component meets RoHS compliance requirements and verify the marking code L43 on the SOT-23 package to ensure authenticity and correct configuration.

Selection Notes

Select this component when a dual Schottky diode with a common cathode topology is required. The SOT-23 package provides a compact footprint ideal for portable electronics. Ensure the application voltage does not exceed the 30 V rating and consider the thermal resistance of 430 °C/W for heat dissipation planning.

Part Context

This component belongs to the BAT54 series, which includes variants like BAT54A (common anode) and BAT54S (series). The BAT54C specifically utilizes the L43 top mark for identification. Originally manufactured by Fairchild Semiconductor, the product line is now managed by ON Semiconductor following corporate integration.
