Overview
The RR274EA-400TR is a dual-line rectifier diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a peak reverse voltage of 400V and an average forward current rating of 500mA. The device exhibits a maximum forward voltage drop of 1.1V at the rated current and a reverse leakage current of 10µA. It supports a maximum surge current of 8A and operates within a junction temperature range up to +150°C. Packaged in a TSMD-5 (SOT-25) housing with five terminals, it is supplied in reel format.
Feature Summary
- Dual-line configuration providing two independent rectifying paths within a single compact package.
- High thermal stability supporting operation at junction temperatures up to +150°C.
- Automotive-grade reliability compliant with AEC-Q101 standards.
Applications
- Automotive electronic circuits requiring high-reliability rectification.
- General-purpose power supply rectification stages.
- Surface-mount assembly processes for compact consumer electronics.
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the specific order matches the RR274EA-400TR designation, as variants may exist. Check for RoHS compliance documentation if environmental regulations apply. Ensure storage conditions align with semiconductor handling guidelines to prevent moisture sensitivity issues prior to reflow soldering.
Selection Notes
Select this component when a dual-channel rectifier solution is required in a small surface-mount footprint. The 400V rating suits medium-voltage applications, while the 500mA current capacity fits low-to-medium power circuits. Consider the TSMD-5 package dimensions for PCB layout constraints. Verify thermal management requirements given the 150°C junction limit.
Part Context
This part belongs to ROHM's RR274 series of standard rectifier diodes. The series is characterized by its automotive qualification and compact plastic molding design. The RR274EA-400TR specifically denotes the dual-line variant with a 400V reverse voltage rating, distinguishing it from single-line or different voltage variants within the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult official ROHM documentation for qualified alternatives or cross-reference similar dual-line 400V rectifiers ensuring matching electrical parameters and package compatibility.
