BAT54CDW-TP

Overview

The BAT54CDW-TP is a surface-mount Schottky barrier diode array manufactured by Micro Commercial Components. It features four silicon diodes arranged in two banks with common cathode configuration within a compact SOT-363 package. The device supports a maximum repetitive reverse voltage of 30 V and an average forward current of 200 mA per diode. Key electrical characteristics include a typical low forward voltage of 0.347 V at 10 mA and a maximum reverse leakage current of 2 µA at 25 V. It operates reliably across a junction temperature range of -55 °C to +125 °C.

Feature Summary

• Dual dual series configuration providing isolated diode arrays for significant board space savings
• Extremely fast switching speed suitable for high-frequency applications
• Very low forward voltage drop characteristic reducing power loss
• Surface mount design ideally suited for automatic insertion processes

Applications

• High-speed signal rectification in consumer electronics
• Clamping and protection circuits in communication equipment
• Power management systems requiring low voltage drop
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm exact pinout and electrical tolerances, as variations may exist within the BAT54 family. Ensure compatibility with RoHS 2002/95/EC directives if required by your manufacturing standards. Cross-reference the datasheet for precise thermal resistance values and recommended soldering profiles to prevent component damage during assembly.

Selection Notes

Select this component when space constraints require multiple diodes in a single small outline package. It is appropriate for designs needing fast recovery times and low forward voltage drops compared to standard PN junctions. Consider the 30 V reverse voltage rating to ensure adequate margin for peak inverse voltages in the target circuit application.
