RB495DT146

Overview

The RB495DT146 is a Schottky barrier diode array manufactured by ROHM Semiconductor. It features a dual configuration within an SOT-346 surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 25V and supports a continuous forward current of 200mA per element. Key electrical characteristics include a low forward voltage drop and fast switching capabilities typical of Schottky technology, designed for efficient rectification in compact electronic circuits.

Feature Summary

• Dual Schottky barrier diode configuration for space-saving designs
• Low forward voltage drop to minimize power loss
• Fast switching performance suitable for high-frequency applications

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Power supply input protection

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors or last-time buy channels. Ensure the ordering suffix matches the required tape-and-reel packaging specifications. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility before integration into new hardware.

Selection Notes

Select this component when a dual Schottky configuration is required in a minimal footprint. Compare the 25V rating and 200mA current limit against circuit requirements. Evaluate thermal management needs based on the SOT-346 package size. Consider alternative single-diode arrays if only one channel is utilized to optimize cost and board space.

Part Context

This part belongs to the RB495 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by silicon epitaxial planar structures offering high reliability and low reverse leakage current. The DT146 suffix indicates the specific dual configuration and SOT-346 packaging format used in modern consumer and industrial electronics.

Replacement Considerations

Check for direct replacements within the RB495 series that may have updated manufacturing statuses. Verify equivalent electrical parameters such as voltage rating, current capacity, and package dimensions. Consult ROHM documentation for recommended substitute parts if the NRND status limits long-term supply chain stability.
