Overview
The RB228NS-40FHTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications including automotive electronics. It features a Dual Anode Common Cathode configuration within a TO-263S (D2PAK) surface-mount package. Key electrical specifications include a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 30 A. The device exhibits a low forward voltage of 0.77 V at 15 A and a maximum reverse current of 10 mA at 40 V. It supports a forward surge current of 100 A and operates at junction temperatures up to +150 °C. The component is qualified under the AEC-Q101 standard.
Feature Summary
- AEC-Q101 qualified for automotive-grade reliability
- Low forward voltage characteristics for efficiency
- Dual Anode Common Cathode configuration
- High thermal stability with +150 °C max operating temperature
Applications
- Automotive power supply circuits
- Switching power supplies
- DC-DC converter freewheeling paths
Procurement Notes
Verify the specific suffix 'TL' against the manufacturer's datasheet to confirm tape-and-reel packaging details. Ensure the ordering part number matches the exact RoHS compliance status and binning requirements specified in the official documentation. Cross-reference the AEC-Q101 qualification status directly with the source data to confirm automotive suitability.
Selection Notes
Select this component when a dual common cathode Schottky diode is required for synchronous rectification or freewheeling in low-voltage, high-current environments. The TO-263S package provides robust thermal performance suitable for board-level mounting. Consider the 40 V rating and 30 A continuous current capacity to ensure adequate headroom for the target application's peak loads.
Part Context
This component belongs to ROHM's line of Schottky barrier diodes optimized for low forward voltage and low reverse leakage current. The RB228NS series is specifically engineered for use in switching power supplies and automotive systems where high reliability and compact surface-mount footprints are critical design constraints.
Replacement Considerations
Consult official substitution lists for equivalent ROHM parts such as the RB228NS-40FH. Verify that any alternative maintains the same TO-263S footprint, AEC-Q101 qualification, and electrical parameters like Vf and Ir.
