The RB088NS-40TL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for switching power supply applications. It features a dual anode common cathode configuration within a TO-263S (D2PAK) surface-mount package. The device supports an average rectified forward current of 10 A and withstands a repetitive peak reverse voltage of 45 V. Key electrical parameters include a maximum forward voltage of 0.77 V at 5 A and a maximum reverse current of 0.003 mA at 40 V. It operates with a junction temperature up to +150 °C and complies with AEC-Q101 automotive standards.
Verify the specific suffix 'TL' against the manufacturer's official datasheet to confirm tape-and-reel packaging details. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Cross-reference the exact part number with authorized distributors to confirm current availability status and lead times. Check RoHS compliance documentation for regulatory adherence.
Select this component when designing circuits requiring a dual-anode Schottky diode with automotive-grade reliability. The TO-263S package offers robust thermal performance for surface-mount applications. Consider the 0.77 V forward voltage drop for efficiency calculations. Verify that the 10 A current rating aligns with the load requirements of the target switching power supply design.
This component belongs to the RB088 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by low forward voltage and ultra-low reverse leakage current, making it suitable for high-efficiency power conversion. The RB088NS variant specifically targets automotive and industrial applications requiring high reliability under varying thermal conditions.
The RB088BM-40TL is listed as a similar level replacement with the same pinout and package. Verify compatibility before substitution.
