RB751S40

Single Diodes Overview

The RB751S40 is a Schottky barrier diode manufactured by onsemi, housed in the SOD-523 surface-mount package. It features a maximum repetitive peak reverse voltage of 40 V and an average forward current rating of 30 mA. The device exhibits an extremely low typical forward voltage of 0.28 V at 1.0 mA DC, which minimizes conduction losses during operation. Designed for high-speed switching applications, it offers fast switching speeds and low reverse current characteristics suitable for circuit protection and voltage clamping tasks.

Single Diodes Feature Summary

• Designed for high-speed switching applications
• Miniature surface mount package suitable for space-limited designs

Single Diodes Applications

• High speed switching applications
• Circuit protection
• Voltage clamping
• Hand held and portable applications

Single Diodes Procurement Notes

Verify the specific ordering suffix (e.g., T1G, T5G) required for your manufacturing process, as the base model number RB751S40 refers to the component family rather than a single purchasable SKU. Confirm AEC-Q101 automotive qualification status if applicable, as this depends on the suffix. Ensure the SOD-523 footprint matches your PCB layout constraints before finalizing procurement.

Single Diodes Selection Notes

Select this component when minimizing forward voltage drop is critical for efficiency in low-current circuits. The SOD-523 package is ideal for compact consumer electronics where board space is restricted. Consider the 40 V reverse voltage rating to ensure adequate headroom for the target application's operating voltage. Verify thermal dissipation requirements against the 200 mW power dissipation limit.

Single Diodes Part Context

This component belongs to the RB751S series of Schottky barrier diodes from onsemi, originally developed under the Fairchild Semiconductor legacy. The series is characterized by its small form factor and low forward voltage profile. It serves as a discrete solution for rectification and protection in modern electronic systems requiring efficient power management in small packages.

Single Diodes Replacement Considerations

Check for equivalents with identical SOD-523 packaging and matching electrical parameters such as 40 V reverse voltage and similar forward voltage characteristics. Ensure any substitute maintains the same switching speed and reverse leakage current specifications to guarantee circuit compatibility.
