RB481Y-40FHT2R

Overview

The RB481Y-40FHT2R is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for automotive applications with AEC-Q101 support. It features a dual line configuration in an EMD4 (SOT-543) surface-mount package. Key electrical parameters include a reverse voltage of 30V, an average rectified forward current of 0.1A, and a maximum forward voltage of 0.43V at 0.1A. The device supports a junction temperature up to 125°C and operates within a storage temperature range of -40°C to 125°C.

Feature Summary

Ultra-small plastic mold type construction for compact circuit designs.
Low forward voltage characteristics for improved efficiency.
High reliability suitable for automotive grade environments.

Applications

Low current rectification circuits
Automotive electronic systems requiring AEC-Q101 compliance

Procurement Notes

Verify the specific ordering suffix and package code against official documentation, as variations exist within the RB481 series. Confirm availability status, as certain variants may be discontinued or not recommended for new designs. Ensure the selected part matches the required reverse voltage and current specifications for the target application.

Selection Notes

Select this component when a dual Schottky diode in a small SOT-543 package is required for automotive use. Compare the 30V rating and 0.1A current limit against system requirements. Consider thermal management capabilities given the 125°C junction temperature limit and low forward voltage drop benefits.

Part Context

This component belongs to the RB481 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by ultra-small packages and high reliability, specifically targeting automotive electronics. The RB481Y variant utilizes the EMD4 package format, distinguishing it from other series members with different pin counts or configurations.
