Overview
The RB481Y-90FHT2R is a silicon 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), measuring 1.6x1.6 mm with a thickness of 0.55 mm. The device supports AEC-Q101 automotive standards and offers a reverse voltage of 90 V and an average rectified forward current of 0.1 A. Key electrical parameters include a maximum forward voltage of 0.61 V at 0.1 A, a maximum reverse current of 0.1 mA at 90 V, and a junction temperature rating of 125 °C.
Feature Summary
- Ultra-small plastic molded type construction for compact circuit designs.
- Low forward voltage characteristic to enhance efficiency in low-current applications.
- High reliability structure suitable for demanding environments.
- Compliance with AEC-Q101 automotive grade standards.
Applications
- Low current rectification circuits
- Automotive electronic systems requiring AEC-Q101 compliance
- Surface-mount assembly for space-constrained PCBs
Procurement Notes
Verify the specific ordering suffix T2R to confirm taping specifications and quantity per reel. Confirm that the component status remains as discontinued or not recommended for new designs before finalizing procurement plans. Ensure compatibility with existing inventory strategies due to potential supply constraints associated with end-of-life products.
Selection Notes
Select this component when a dual-line Schottky diode with high reverse voltage capability is required in a minimal footprint. Consider the 0.1 A current limit and 125 °C junction temperature against system thermal requirements. Evaluate the EMD4 package dimensions against available land pattern constraints on the target printed circuit board layout.
Part Context
This part belongs to the RB481Y series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by small size and low forward voltage drop. The RB481Y-90FHT2R specifically denotes the 90 V reverse voltage variant packaged in tape and reel format for automated surface-mount processing.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source data. Verify alternative components based on matching electrical ratings and package dimensions if replacement is necessary.
