• Dual common cathode configuration for efficient circuit design
• Super low reverse leakage current to minimize power loss
• High thermal stability with a maximum junction temperature of 150°C

Applications

• Automotive power supply circuits
• DC-DC converter modules
• High-efficiency rectification in switching power supplies

Procurement Notes

Verify the specific suffix FHTL against the official ROHM datasheet to confirm the tape-and-reel packaging format and quantity. Ensure the procurement channel provides documentation confirming AEC-Q101 compliance. Cross-reference the part number with the manufacturer's latest release notes to confirm active status for new designs, as some variants may be designated for existing customers only.

Selection Notes

Select this component when designing automotive systems requiring robust Schottky rectification with high current handling capabilities. The TO-263-3 package offers superior thermal dissipation compared to smaller surface-mount options. Consider the 60 V rating relative to system voltage spikes and ensure the 40 A current capacity aligns with peak load requirements without exceeding thermal limits.

Part Context

This device belongs to the RB238 series of Schottky barrier diodes from ROHM, specifically engineered for automotive electronics. The series emphasizes high reliability and low forward voltage drop to enhance energy efficiency. The RB238NS-60FHTL variant utilizes a D²Pak package to balance current capacity with compact board space, serving as a critical component in modern vehicle power management architectures.

Replacement Considerations

Direct substitutes within the same series include RB238NS-60FH and RB238NS-60TL. Verify pinout compatibility and thermal resistance values before substitution. Alternative packages such as TO-220FN variants like RB238T-60HZ offer similar electrical specifications but require different mounting considerations.
