RB481YFHT2R

Overview

The RB481YFHT2R is a Schottky Barrier Diode manufactured by ROHM Semiconductor, designed for surface mount applications. It features a dual line configuration within an EMD4 (SOT-543) package. 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 spanning from -40°C to 125°C.

Feature Summary

Ultra-small plastic mold type construction for compact circuit designs
Low forward voltage characteristic for improved efficiency
High reliability performance suitable for demanding environments

Applications

Low current rectification circuits
Automotive electronic systems requiring AEC-Q101 compliance
General purpose signal diode applications

Procurement Notes

Verify the manufacturing status before procurement as this component may be discontinued or not recommended for new designs. Confirm the specific ordering suffix matches the required tape and reel quantity. Ensure compatibility with existing PCB land patterns for the EMD4 package. Check for alternative replacement parts if long-term supply stability is required for production cycles.

Selection Notes

Select this component when a dual-line Schottky diode in a minimal footprint is required for low-current applications. The AEC-Q101 qualification makes it suitable for automotive integration where high reliability is mandatory. Consider the 30V reverse voltage limit and 0.1A current capacity against circuit demands. Evaluate the thermal management requirements given the 125°C junction temperature specification.

Part Context

This part belongs to ROHM's RB481 series of Schottky Barrier Diodes, which are characterized by their small size and low forward voltage drop. The series is widely used in consumer electronics and automotive equipment due to its high reliability and compact EMD4 packaging. The RB481YFHT2R specifically denotes the taping version of the standard RB481YF device.
