Overview
The RB481YFJT2R is a Schottky Barrier Diode manufactured by Rohm Semiconductor, designed for surface mount applications. It features an EMD4 package (JEITA SC-107A) with four terminals and supports AEC-Q101 automotive standards. 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 input. The device exhibits a maximum reverse current of 0.03mA at 10V reverse bias and operates within a junction temperature range up to 125°C.
Feature Summary
- Ultra-small plastic molded 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 suffix 'JT' against official Rohm documentation, as standard listings often reference 'FH'. Confirm manufacturing status, as related variants like RB481YFH are marked as discontinued. Ensure the ordering part number matches the exact tape and reel quantity specifications required for production integration.
Selection Notes
Select this component for space-constrained designs requiring low forward voltage drop in small surface-mount packages. Verify that the 0.1A current rating and 30V reverse voltage meet circuit requirements. Consider the EMD4 footprint compatibility during PCB layout and confirm thermal management capabilities for the specified junction temperature limits.
Part Context
This component belongs to the RB481 series of Schottky Barrier Diodes from Rohm Semiconductor. The series is characterized by ultra-small packaging and high reliability, targeting applications where minimal footprint and efficient rectification are critical. It aligns with automotive grade standards for enhanced durability.
Replacement Considerations
Official documentation lists RB521SM-30 as a recommended replacement for similar specifications. Verify pinout compatibility and electrical parameter alignment before substitution.
