RB715UMTL

Overview

The RB715UMTL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-speed switching applications in surface-mount technology. It features a dual anode common cathode configuration within a compact SOT-323FL-3 package. The device operates with a maximum repetitive reverse voltage of 40 V and supports an average forward current of 30 mA. Key electrical characteristics include a forward voltage of 370 mV at 1 mA and a low reverse current of 1 uA at 10 V. It withstands a forward surge current of 200 mA and functions reliably up to a maximum junction temperature of +125 C.

Feature Summary

• Dual anode common cathode configuration enables flexible circuit design for signal processing and logic level shifting.
• Low forward voltage drop minimizes power loss during conduction phases.
• Ultra-low reverse leakage current ensures minimal standby power consumption.
• High-speed switching capability reduces recovery time losses in high-frequency circuits.

Applications

• High-speed switching circuits in portable electronic devices
• Signal rectification in mobile phone power management systems
• Logic level translation in computer peripheral interfaces

Procurement Notes

Verify the specific suffix 'UMTL' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status aligns with current environmental regulations for the target market. Ensure the ordering quantity matches the standard factory pack size of 3000 units to avoid partial reel handling issues during production integration.

Selection Notes

Select this component when a dual-diode arrangement is necessary within a minimal footprint constraint. The SOT-323FL-3 package offers space efficiency compared to larger discrete packages. Consider the 40 V rating for low-voltage DC-DC converter outputs or battery-powered systems where higher voltage ratings are unnecessary. Evaluate the 30 mA current limit against peak load requirements to ensure adequate thermal headroom.

Part Context

This part belongs to ROHM's RB715 series of Schottky barrier diodes, which are optimized for low voltage and high-speed performance. The series is widely used in consumer electronics due to its balance of electrical performance and physical size. The UM suffix indicates the specific UMD3F (SOT-323FL) package variant, distinguishing it from other pin-compatible or electrically similar parts in the broader diode portfolio.

Replacement Considerations

The RB715ZMTL is documented as a recommended replacement with the same pinout and package. Verify electrical parameter equivalence before substitution. Other variants like RB715WMFHTL offer automotive qualification but differ in package type.
