RN262CST2R

RF Diode Overview

The RN262CST2R is a silicon PIN diode manufactured by ROHM Semiconductor, designed for high-frequency switching applications. It features a reverse voltage rating of 30 V and supports a maximum forward current of 100 mA with a forward voltage of 1 V. The device exhibits a maximum junction capacitance of 400 fF and a series resistance ranging from 1.5 to 2.8 Ohms depending on the frequency conditions. With a power dissipation capacity of 100 mW and an operating temperature range up to +150 C, it is housed in a surface-mount SMD/SMT package within the RN262CS series.

RF Diode Feature Summary

• Ultra-small mold type construction suitable for compact designs
• Low high-frequency forward resistance and low capacitance characteristics

RF Diode Applications

• High frequency switching circuits

RF Diode Procurement Notes

Verify the current lifecycle status before procurement as this component is classified as NRND (Not Recommended for New Designs). Confirm that existing inventory or last-time-buy options align with long-term production requirements. Ensure compatibility with RoHS standards and verify the specific reel packaging quantity matches the manufacturing line needs.

RF Diode Selection Notes

Select this component when a small form factor PIN diode with low capacitance is required for RF switching. Compare the 30 V reverse voltage and 400 fF capacitance against circuit requirements. Consider the RN262G series if a different package size or slightly different electrical parameters are acceptable for the design.

RF Diode Part Context

This part belongs to the RN262CS series of silicon PIN diodes from ROHM Semiconductor. It utilizes a silicon epitaxial planar structure and is packaged in the VMN2 format. The series is specifically engineered for applications demanding ultra-small dimensions and efficient high-frequency performance.

RF Diode Replacement Considerations

The RN142SM (Ordering Part Number: RN142SMT2R) is documented as a replacement with similar specifications. Note that the RN142SM uses an EMD2 (SOD-523) package, which differs physically from the original VMN2 package.
