RB715UMFHTL

Overview

The RB715UMFHTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-speed switching applications. It features a dual cathode common anode configuration within a compact SOT-323FL-3 (UMD3F) surface-mount package. The device operates with a maximum repetitive reverse voltage of 45V and supports an average rectified forward current of 30mA. Key electrical parameters include a maximum forward voltage of 370mV at 1mA, a peak forward surge current capability of 200mA, and a maximum reverse current of 1µA. It is qualified for automotive use under the AEC-Q101 standard and functions reliably within a junction temperature range up to +125°C.

Feature Summary

• Dual cathode common anode configuration for efficient circuit integration
• Automotive-grade reliability certified to AEC-Q101 standards
• Low forward voltage characteristic optimized for high-speed switching

Applications

• High-speed switching circuits in automotive electronics
• Power management systems requiring low-loss rectification
• Portable electronic devices utilizing surface-mount technology

Procurement Notes

Verify the specific suffix HTL confirms the reel packaging format required for automated assembly processes. Confirm that the AEC-Q101 qualification aligns with your target automotive application's reliability requirements. Ensure the SOT-323FL-3 footprint matches your PCB design constraints. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when a dual-diode solution with a common anode is required in a minimal footprint. The 45V rating provides sufficient headroom for low-voltage automotive and consumer applications. The AEC-Q101 certification makes it suitable for environments demanding higher reliability than standard industrial grades. Consider the 30mA current limit when designing load paths to avoid exceeding thermal limits.

Part Context

This part belongs to ROHM's RB715 series of Schottky barrier diodes, which are engineered for low forward voltage and fast recovery characteristics. The UMFHTL variant specifically denotes the surface-mount version in the UMD3F package with tape-and-reel delivery. This series is distinct from through-hole or higher-current variants, focusing on compactness and efficiency for signal and low-power rectification tasks.

Replacement Considerations

The RB715WMFHTL serves as a verified alternative within the same series, offering identical electrical performance but housed in the slightly larger SOT-416FL package. Designers must verify mechanical fitment before substitution due to the difference in package dimensions.
