RN242CST2RA

RF Diode Overview

The RN242CST2RA is a PIN diode manufactured by ROHM Semiconductor, designed for high-frequency switching applications. It features a reverse voltage of 30 V and a maximum forward current of 100 mA. The device exhibits a low junction capacitance of 0.35 pF at 1 V reverse bias and a typical RF resistance of 3.0 Ohms at 100 MHz with 3 mA forward current. Operating within a temperature range of -55°C to +150°C, it utilizes an SOD-923 (VMN2) surface-mount package.

RF Diode Feature Summary

• Ultra-small mold type construction for compact circuit layouts
• Low high-frequency resistance and low capacitance characteristics
• Silicon epitaxial planer structure for reliable performance

RF Diode Applications

• High frequency switching circuits
• RF signal routing and attenuation
• Microwave communication systems

RF Diode Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm the tape-and-reel packaging format. Ensure compatibility with existing PCB footprints designated for the SOD-923 package. Confirm supply status as this component may be subject to production lifecycle changes.

RF Diode Selection Notes

Select this component when a small footprint and low parasitic capacitance are required for RF switching. Compare specifications against the RN242SMT2R if a larger SOD-523 package is acceptable for easier handling. Verify that the 30 V reverse voltage rating meets the peak inverse voltage requirements of the target application.

RF Diode Part Context

This part belongs to the RN242 series of PIN diodes from ROHM Semiconductor. It shares similar electrical characteristics with the RN242CS but differs in packaging. The series is engineered for high-speed switching operations where low insertion loss and fast recovery times are critical parameters.

RF Diode Replacement Considerations

The RN242SMT2R is listed as a recommended replacement with similar specifications. Both parts share identical electrical ratings but utilize different packages: SOD-923 for the RN242CST2RA and SOD-523 for the RN242SMT2R. Footprint adaptation is required for substitution.
