RB085BM-60FHTL

Overview

The RB085BM-60FHTL is a Schottky barrier diode manufactured by Rohm Semiconductor, designed for high-efficiency rectification in power supply circuits. It features a maximum repetitive peak reverse voltage of 60V and an average forward rectified current rating of 8A at a case temperature of 75°C. The device utilizes a surface-mount SMC (DO-214AB) package, providing robust mechanical stability and thermal performance. Key electrical characteristics include a low forward voltage drop of approximately 0.53V at rated current, ensuring minimal power loss during operation.

Feature Summary

• Schottky barrier construction for fast switching speeds and low reverse recovery charge
• Low forward voltage drop to enhance overall system efficiency
• Surface-mount SMC package design for automated assembly and compact board layouts

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Power supply input protection

Procurement Notes

Verify the specific suffix FHTL corresponds to the required tape-and-reel packaging quantity and marking configuration. Confirm that the 60V voltage rating aligns with the circuit's peak inverse voltage requirements. Ensure the SMC footprint matches the PCB design guidelines provided in the official datasheet to guarantee proper solder joint integrity and thermal dissipation.

Selection Notes

Select this component when applications require high current handling capabilities combined with low conduction losses. The 60V rating suits low-voltage DC systems where standard silicon diodes would incur excessive voltage drops. Consider the thermal resistance of the SMC package relative to the expected ambient temperature and heat sinking conditions to maintain junction temperatures within safe operating limits.

Part Context

This part belongs to Rohm's RB085BM series of Schottky barrier rectifiers. The series is engineered for general-purpose power conversion applications requiring reliable performance under moderate voltage stresses. The BM variant typically denotes specific internal structural optimizations for reduced leakage current and improved thermal stability compared to standard variants.

Replacement Considerations

Direct substitutes must match the 8A current rating, 60V reverse voltage, and SMC package outline. Verify equivalent forward voltage and reverse leakage specifications to ensure no degradation in circuit efficiency or reliability.
