RB715WMFHTL

Overview

The RB715WMFHTL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-speed switching applications in automotive environments. It features a dual anode common cathode configuration within a compact SOT-416FL (SC-89) surface-mount package. The device supports a maximum repetitive reverse voltage of 40V and an average rectified forward current of 30mA. Key electrical characteristics include a maximum forward voltage of 370mV at 1mA and a low reverse current of 1µA at 10V. It is qualified under the AEC-Q101 standard, ensuring reliability for automotive grade usage, with an operating junction temperature range up to +125°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for harsh environment durability
• Low forward voltage characteristic enables efficient power conversion and reduced heat generation
• Compact SOT-416FL surface-mount package facilitates automated assembly and space-constrained designs

Applications

• High-speed switching circuits in automotive electronic control units
• Power supply rectification in vehicle infotainment systems
• Protection diodes in automotive sensor interfaces

Procurement Notes

Verify the specific suffix HTL confirms the tape-and-reel packaging format required for automated placement equipment. Confirm that the AEC-Q101 qualification status meets the specific reliability class requirements of the target automotive application. Ensure the SOT-416FL footprint matches the PCB land pattern design to prevent soldering defects during reflow processes.

Selection Notes

Select this component when a small-form-factor Schottky diode with automotive certification is required. The 40V rating suits low-voltage automotive bus architectures. The dual anode common cathode structure allows for bridge rectifier or logic gate configurations within a single package, reducing component count compared to discrete alternatives.

Part Context

This part belongs to ROHM's RB715 series of Schottky barrier diodes, specifically engineered for automotive electronics. The 'WM' designation typically indicates the specific internal die and packaging variant optimized for low leakage and fast recovery. It is distinct from the standard commercial RB715F series, which lacks the rigorous automotive qualification testing.

Replacement Considerations

The RB715WMFH is the non-tape version of the same device. For cross-brand replacements, verify that any substitute also holds AEC-Q101 certification and matches the 40V/30mA ratings within the SOT-416FL package dimensions.
