RB425D-TP

Overview

The RB425D-TP is a Schottky barrier rectifier diode array manufactured by Micro Commercial Components. It features a common cathode configuration with two independent diodes housed in a SOT-23 surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 40V and an average forward rectified current of 100mA. Designed for low-loss high-frequency applications, it utilizes a metal-semiconductor junction to minimize switching losses.

Feature Summary

• Schottky barrier construction ensures fast switching speeds and minimal reverse recovery charge
• Common cathode dual-diode topology allows efficient space-saving circuit designs
• Low forward voltage drop reduces power dissipation and improves system efficiency

Applications

• DC-DC converter output rectification
• Free-wheeling diode in inductive load circuits
• Protection against reverse polarity in battery-powered devices

Procurement Notes

Verify the component authenticity through official MCC channels or authorized distributors. Confirm that the received parts match the RB425D-TP marking and SOT-23 package specifications. Ensure compliance with RoHS directives if required for your specific manufacturing standards. Request batch-specific datasheets to validate electrical parameters against design requirements before integration.

Selection Notes

Select this component when a compact dual-diode solution is required for low-voltage, low-current applications. The SOT-23 package offers a small footprint suitable for dense PCB layouts. Consider the 40V reverse voltage rating and 100mA current limit to ensure adequate margin for the target operating conditions. Evaluate thermal performance based on the expected ambient temperature and heat dissipation capabilities of the substrate.

Part Context

This part belongs to the RB4xx series of Schottky diode arrays from Micro Commercial Components. These components are designed to replace standard PN junction rectifiers in applications where speed and efficiency are critical. The series provides various configurations including common cathode and common anode options within small outline packages.

Replacement Considerations

Direct replacements must maintain the 40V reverse voltage, 100mA current rating, and SOT-23 package form factor. Verify that substitute parts offer comparable forward voltage characteristics and switching speeds. Check pinout compatibility to ensure seamless integration without circuit modification.
