Overview
The RB481Y-90T2R is a dual-line Schottky barrier diode manufactured by ROHM Semiconductor. It features a silicon epitaxial planar construction housed in an ultra-small EMD4 (SOT-543/SC-75A) surface-mount package with four terminals. The device supports AEC-Q101 automotive standards, ensuring high reliability for demanding environments. Key electrical parameters include a maximum repetitive reverse voltage of 90 V and an average rectified forward current of 0.1 A. The component exhibits a low forward voltage of 0.61 V at 0.1 A and a maximum reverse current of 0.1 mA at 90 V. It operates within a junction temperature range up to 125 °C.
Feature Summary
- Ultra-small power mold type for compact circuit board layouts
- Low forward voltage characteristic for improved efficiency
- High reliability compliant with AEC-Q101 automotive standards
Applications
- Automotive electronic circuits requiring robust signal rectification
- Low current rectification tasks in consumer electronics
- General-purpose signal processing applications
Procurement Notes
Verify the specific suffix 'T2R' against official documentation to confirm tape-and-reel packaging specifications. Confirm that the part meets current RoHS directives and lead-free requirements as stated in the datasheet. Ensure compatibility with existing PCB land patterns defined for the EMD4 package before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel configuration is required in a minimal footprint. The 90 V reverse voltage rating suits applications with moderate voltage spikes. Consider the 0.1 A current limit for low-power signal paths rather than high-current power delivery systems. Verify thermal management needs given the small package size and 125 °C junction temperature limit.
Part Context
This component belongs to ROHM's RB481 series of Schottky barrier diodes designed for general-purpose and automotive applications. The series emphasizes miniaturization through the EMD4 package while maintaining high reliability. It serves as a specialized solution for space-constrained designs requiring dual-diode functionality without sacrificing performance or durability.
Replacement Considerations
The RB481Y-90FH is documented as a related variant within the same product family. Note that the RB481Y-90FH status is listed as manufacturing discontinued. Verify pinout and electrical equivalence carefully if considering alternative dual Schottky diodes from other manufacturers.
