Overview
The RBR40NS30ATL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, designed for use in switching power supplies. It features a dual anode common cathode configuration housed in a TO-263S (D2PAK) surface-mount package. The device supports a repetitive peak reverse voltage of 30V and an average rectified forward current of 40A. Key electrical characteristics include a maximum forward voltage of 0.52V at 20A and a peak forward surge current capability of 100A. The component operates within a junction temperature range up to +150°C and complies with RoHS standards.
Feature Summary
- Low forward voltage design optimized for high efficiency in switching applications
- High reliability construction using silicon epitaxial plane technology
- Power mold type packaging suitable for surface mount assembly
- Capable of handling high peak forward surge currents
Applications
- Switching power supply circuits
- Freewheeling diode applications
- DC-DC converter output rectification
Procurement Notes
Verify the specific suffix 'TL' against the manufacturer's official datasheet to confirm tape and reel packaging specifications. Ensure the selected variant matches the required 30V rating and 40A current capacity for the target application. Confirm compliance with AEC-Q101 if automotive qualification is required, as standard versions may differ from automotive-grade counterparts.
Selection Notes
Select this component when a low forward voltage drop is critical for minimizing conduction losses in 30V systems. The TO-263S package provides adequate thermal performance for 40A continuous current applications. Compare the 0.52V forward voltage specification against alternative devices to ensure optimal efficiency. Verify that the common cathode configuration aligns with the circuit topology requirements.
Part Context
This part belongs to the RBR40NS series of Schottky barrier diodes from ROHM Semiconductor. The series includes variants with different reverse voltage ratings, such as 40V and 60V options, all sharing similar current handling capabilities and package styles. These diodes are engineered to balance low forward voltage with low reverse leakage current, making them suitable for general-purpose rectification in power electronics.
Replacement Considerations
Direct substitutes include other RBR40NS series parts with matching voltage ratings, such as RBR40NS40AFHTL or RBR40NS60AFHTL, provided the reverse voltage margin is sufficient. Cross-brand replacements must match the 40A current rating, TO-263S package, and low VF characteristics. Verify pinout compatibility and thermal resistance values before substitution.
