RB706W-40TL

Overview

The RB706W-40TL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for low forward voltage and low reverse current applications. It features a series-connected dual configuration within an EMD3 (SOT-416) surface-mount package. Key electrical specifications include a maximum repetitive peak reverse voltage of 45 V and an average rectified forward current rating of 30 mA. The device exhibits a maximum forward voltage of 0.37 V at a forward current of 1 mA and a maximum reverse current of 1 µA at 10 V. It supports a junction temperature up to 125 °C and operates within a storage temperature range of -40 °C to 125 °C.

Feature Summary

• Low forward voltage characteristic for improved efficiency in portable electronics
• High ESD strength suitable for sensitive consumer devices
• Ultra-small plastic package design for compact board layouts

Applications

• Computers
• Mobile phones
• Portable electronic products

Procurement Notes

Verify the specific suffix TL against the official datasheet to confirm tape-and-reel packaging details. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the application does not involve automotive equipment, as this standard-grade product is explicitly not recommended for such use cases. Cross-reference the EMD3 package code with JEITA SOT-416 standards during PCB footprint design.

Selection Notes

Select this component for low-power signal rectification or clamping in battery-operated devices where space is limited. The series connection configuration allows for handling higher voltages than single diodes while maintaining a small footprint. Consider the 30 mA current limit when designing power paths. The 125 °C junction temperature rating is sufficient for most consumer electronics environments but may require thermal analysis in densely packed assemblies.

Part Context

This part belongs to ROHM's Schottky Barrier Diode family, which emphasizes low VF and low IR characteristics. The RB706 series is specifically engineered for high reliability in small plastic packages. Unlike automotive-grade variants like the RB876WFH, this standard-grade diode focuses on cost-effective solutions for general consumer electronics rather than high-reliability automotive applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult ROHM technical support for direct replacements or evaluate similar SOT-416 Schottky diodes from other manufacturers based on matching electrical parameters.
