Overview
The RB705DT146 is a Schottky barrier diode manufactured by ROHM Semiconductor, housed in an SOT-346-3 surface-mount package. It features a dual anode common cathode configuration with a maximum repetitive reverse voltage of 40 V and a forward current rating of 30 mA. The device exhibits a typical forward voltage of 370 mV at 1 mA and a maximum reverse leakage current of 1 uA at 30 V. It supports a forward surge current of 200 mA and operates within a junction temperature range up to +125 C.
Feature Summary
- Dual anode common cathode configuration for efficient space-saving circuit design
- Low forward voltage characteristic to minimize power loss during conduction
- High reliability construction suitable for automotive applications
Applications
- Automotive electronic systems requiring low-voltage rectification
- General-purpose signal switching circuits
- Power supply output rectification stages
Procurement Notes
Verify the specific ordering suffix matches the required packaging format, such as cut tape or reel quantities. Confirm RoHS compliance status through official documentation before integration. Ensure the component meets AEC-Q101 standards if deployed in automotive environments. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and authenticity.
Selection Notes
Select this component when a compact dual-diode solution is required for low-current applications. The SOT-346-3 package offers a small footprint ideal for dense PCB layouts. Consider the 40 V reverse voltage rating to ensure adequate margin against transient spikes. Evaluate the 30 mA forward current limit against peak load requirements to prevent thermal overstress.
Part Context
This component belongs to the RB705D series of Schottky diodes from ROHM Semiconductor. The series is designed for high-speed switching and low-power rectification tasks. The RB705DT146 variant specifically integrates two diodes in a single package to reduce board space. It targets markets demanding high reliability and compact form factors.
Replacement Considerations
The RB705D is listed as an alias for this part number. Verify pin compatibility and electrical parameters when substituting with other dual Schottky diodes in similar packages.
