RB481Y-40T2R

Overview

The RB481Y-40T2R is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a dual line configuration within an EMD4 package (JEITA SC-107A). The device supports AEC-Q101 automotive standards and operates with a maximum reverse voltage of 30V and an average rectified forward current of 0.1A. Key electrical parameters include a maximum forward voltage of 0.43V at 0.1A input current and a maximum reverse current of 0.03mA at 10V reverse bias. The junction temperature rating reaches 125°C, with a storage temperature range from -40°C to 125°C.

Feature Summary

Ultra-small plastic mold type construction
Low forward voltage characteristic
High reliability design

Applications

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

Procurement Notes

Verify the specific ordering suffix T2R against official documentation to confirm taping specifications and packaging quantity. Confirm availability status as manufacturing discontinuance may affect supply chain continuity. Ensure component authenticity through authorized channels and validate RoHS compliance markings on received units.

Selection Notes

Select this component for designs requiring compact dual-line Schottky rectification in automotive or high-reliability environments. The EMD4 package suits space-constrained surface-mount layouts. Evaluate thermal management requirements against the 125°C junction limit and ensure circuit voltages remain within the 30V reverse voltage specification.

Part Context

This part belongs to ROHM's RB481 series of Schottky barrier diodes. The series emphasizes miniaturization and low power loss characteristics suitable for modern electronics. The RB481Y variant specifically denotes the dual line configuration housed in the EMD4 package, distinguishing it from single-line counterparts in the same family.
