Overview
The RB480Y-90T2R is a dual Schottky barrier diode manufactured by ROHM Semiconductor. It features a reverse voltage of 90 V and an average rectified forward current of 100 mA per element. The device utilizes a SOT-543 (EMD4) surface-mount package with four terminals. Key electrical characteristics include a maximum forward voltage of 0.61 V at 100 mA and a maximum reverse leakage current of 0.1 µA at 90 V. It supports a junction temperature up to 125 °C and complies with AEC-Q101 automotive standards.
Feature Summary
- Dual configuration integrating two independent Schottky barriers in a compact surface-mount footprint.
- Automotive-grade reliability compliant with AEC-Q101 qualification standards for harsh environments.
- Low forward voltage design optimized for high efficiency and reduced power dissipation.
- High-reliability construction utilizing ultra-small plastic encapsulation technology.
Applications
- Automotive general-purpose rectification circuits
- DC-DC converter freewheeling applications
- Power supply output rectification
Procurement Notes
Verify the specific suffix T2R against the official datasheet to confirm the taping reel quantity and packaging format. Ensure the component meets the required AEC-Q101 grade if used in automotive designs. Cross-reference the EMD4 package code with PCB footprint libraries to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a dual Schottky configuration is required within a minimal board area constraint. The 90 V rating suits low-voltage DC systems, while the 100 mA current capacity supports moderate load applications. Consider the 125 °C junction limit for thermal management in enclosed automotive enclosures where ambient temperatures may fluctuate significantly.
Part Context
This part belongs to the RB480Y series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by its small plastic package and high reliability, specifically designed for automotive electronics. The RB480Y-90 variant provides a 90 V reverse voltage rating, distinguishing it from lower or higher voltage counterparts within the same product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications before considering any alternative components from other manufacturers.
