Overview
The RB225NS-40FHTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a dual common cathode configuration within a TO-263S (D2PAK) package. The device supports an average rectified forward current of 30 A and a repetitive reverse voltage of 40 V. Key electrical parameters include a maximum forward voltage of 0.77 V at 15 A and a maximum reverse current of 10 mA at 40 V. The component operates with a junction temperature up to +150°C and is supplied in tape-and-reel packaging.
Feature Summary
- Dual common cathode configuration for efficient power management
- Low forward voltage characteristics to minimize conduction losses
- High reliability suitable for automotive-grade switching power supplies
Applications
- Automotive switching power supply circuits
- DC/DC converter modules
- General-purpose rectification in portable electronic devices
Procurement Notes
Verify the specific suffix FHTL against the official datasheet to confirm the tape-and-reel packaging quantity and lead time requirements. Ensure the design accommodates the TO-263S footprint dimensions. Confirm RoHS compliance status for the specific batch. Check for any end-of-life or not-recommended-for-new-designations that may impact long-term availability.
Selection Notes
Select this component when a low-profile surface-mount Schottky diode with high current capacity is required. The 40V rating suits low-voltage DC-DC conversion stages. Compare thermal performance against through-hole alternatives if heatsinking is limited. Ensure the PCB layout supports the D2PAK thermal pad for optimal heat dissipation during continuous 30A operation.
Part Context
This part belongs to ROHM's RB225 series of Schottky barrier diodes, which are engineered for low forward voltage and high surge current handling. The series targets applications requiring compact form factors and high efficiency. The TO-263S package provides a balance between thermal performance and space constraints in modern electronics.
Replacement Considerations
Consult the official ROHM replacement guide for direct equivalents. Verify pin compatibility and thermal resistance values before substituting. Ensure the alternative part meets the same AEC-Q101 automotive qualification standards if used in vehicle systems.
