RB886CST2R

RF Diode Overview

The RB886CST2R is a detection Schottky diode manufactured by ROHM Semiconductor, supplied in the SOD-923 (VMN2M) surface-mount package. It features a single configuration with two terminals and supports a maximum reverse voltage of 5V and an average forward current of 10mA. The device exhibits a low forward voltage of 0.35V at 1mA and a junction capacitance of 0.8pF at 1V reverse bias. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

RF Diode Feature Summary

• Low junction capacitance for high-frequency detection applications
• Compact SOD-923 surface-mount package design
• High reliability construction suitable for consumer electronics

RF Diode Applications

• High-frequency signal detection circuits
• RF demodulation stages
• Consumer electronic device protection

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation, as variations such as T2R indicate tape-and-reel packaging quantities. Confirm supply status directly with the manufacturer or authorized distributors, as availability may vary based on production lifecycle stages. Ensure compatibility with existing PCB footprints designated for the SOD-923 package type.

RF Diode Selection Notes

Select this component when a low-capacitance Schottky barrier diode is required for small-signal detection rather than power rectification. The 5V reverse voltage rating limits its use to low-voltage signal paths. Compare the 0.8pF capacitance against alternative packages like SOD-723 if space constraints allow, noting that smaller packages may offer similar electrical performance in different form factors.

RF Diode Part Context

This part belongs to ROHM's RB886 series of detection Schottky diodes, designed specifically for high-speed switching and signal processing tasks. The series emphasizes low parasitic capacitance to maintain signal integrity at higher frequencies. It serves as a compact solution for modern miniaturized electronic designs requiring reliable semiconductor junctions.

RF Diode Replacement Considerations

The RB886CM is listed as a recommended replacement with similar specifications. Verify pinout compatibility and package dimensions before substitution. Other variants in the RB886 family may share electrical characteristics but differ in packaging or termination styles.
