Overview
The RBQ20NS100AFHTL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, housed in a TO-263S (D2PAK) surface-mount package. It features a dual anode common cathode configuration with a maximum repetitive reverse voltage of 100 V and an average forward current rating of 20 A. The device exhibits a maximum forward voltage of 770 mV at 10 A and a maximum reverse current of 140 uA at 100 V. It supports a forward surge current of 100 A and operates at junction temperatures up to +150 °C. This component meets the AEC-Q101 automotive reliability standard.
Feature Summary
- Dual anode common cathode configuration for efficient rectification
- Automotive-grade reliability compliant with AEC-Q101 standards
- Low leakage current characteristics for improved efficiency
- High thermal stability supporting operation up to 150 °C
Applications
- Automotive general rectification circuits
- DC-DC converter output stages
- Power supply freewheeling applications
Procurement Notes
Verify the specific suffix AFHTL against the official ROHM datasheet to confirm AEC-Q101 qualification and tape-and-reel packaging specifications. Ensure the ordering part number matches the required automotive grade and package variant. Cross-reference the manufacturer's latest documentation for any updates on lead-free plating or anti-whisker formation requirements relevant to this specific component revision.
Selection Notes
Select this component when designing circuits requiring a 100 V rated Schottky diode with a 20 A continuous current capacity in a D2PAK package. The dual anode common cathode structure allows for use in full-wave rectification or synchronous rectification topologies. Consider the 770 mV forward voltage drop for thermal management calculations and ensure the PCB layout supports the thermal dissipation capabilities of the TO-263S package for reliable high-temperature operation.
Part Context
This part belongs to the RBQ series of low reverse current Schottky barrier diodes from ROHM Semiconductor. The series is designed for high-efficiency power conversion applications. The RBQ20NS100AFHTL specifically targets automotive electronics due to its AEC-Q101 certification, distinguishing it from non-automotive variants within the same electrical specification family.
Replacement Considerations
The RBQ20NS100A is listed as an alias for this component. Verify if the 'FHTL' suffix denotes specific packaging or automotive qualification differences compared to the base part number before substitution.
