Overview
The RB205T-90 is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications. It features a common cathode configuration within a TO-220FN (3-pin) package. The device supports an average rectified forward current of 20A and withstands a reverse voltage of 90V. Key electrical characteristics include a maximum forward voltage of 0.75V at 10A and a maximum reverse current of 0.4mA at 90V. The component operates with a junction temperature up to 150°C and complies with RoHS standards.
Feature Summary
- Common cathode dual-anode configuration in a leaded TO-220 package
- Low reverse current design ensuring high reliability
- Automotive-grade qualification under AEC-Q101 standard
Applications
- Automotive power supply circuits requiring AEC-Q101 compliance
- High-current DC-DC converter output rectification
- Free-wheeling diodes in motor drive systems
Procurement Notes
This component is designated as Not Recommended for New Designs (NRND). Production is limited to supporting existing customers only; new design introductions are not accepted. Verify current availability status directly with the manufacturer or authorized distributors before initiating procurement processes for legacy projects.
Selection Notes
Select this part for applications requiring a robust 20A Schottky rectifier with low forward voltage drop in a through-hole package. Ensure the design accommodates the NRND status if long-term supply continuity is critical. Compare thermal management requirements against the 150°C junction limit and verify that the 90V reverse voltage rating exceeds peak circuit voltages.
Part Context
The RB205T-90 belongs to ROHM's RB2xxT series of silicon Schottky barrier diodes. This series is characterized by low forward voltage and high surge current capability. The specific model utilizes a TO-220FN package to handle significant power dissipation while maintaining a compact footprint suitable for industrial and automotive chassis mounting.
Replacement Considerations
Verify pinout compatibility with TO-220FN packages when substituting. Check equivalent reverse voltage and forward current ratings. Note that alternative parts may lack AEC-Q101 certification unless explicitly specified.
