RN141CMT2R

RF Diode Overview

The RN141CMT2R is a single PIN diode manufactured by Rohm Semiconductor, designed for high-frequency switching applications. It features a reverse voltage of 50V and a forward current rating of 100mA. The device exhibits a low junction capacitance of 0.8pF at 1V reverse bias and a low forward resistance of 2.0Ω at 3mA forward current. It operates within a temperature range of -55°C to 150°C and is housed in an SOD-923 (VMN2M) surface-mount package with dimensions of 1.0x0.6mm.

RF Diode Feature Summary

• Low junction capacitance optimized for high-speed signal processing
• Compact surface-mount package suitable for space-constrained designs
• High thermal stability with elevated maximum junction temperature

RF Diode Applications

• RF switch circuits
• High-frequency signal modulation

RF Diode Procurement Notes

Verify the ordering part number RN141CMT2R against the specific datasheet revision required for your design. Confirm that the SOD-923 package dimensions align with your PCB footprint constraints. Ensure compliance with RoHS directives if applicable to your manufacturing region. Check for any specific handling requirements during assembly due to the small form factor.

RF Diode Selection Notes

Select this component when a low-capacitance PIN diode is needed for frequencies around 1MHz to 100MHz. Compare the 0.8pF capacitance and 2.0Ω resistance against alternative packages like SOD-723 to determine the best fit for impedance matching. Consider the 50V reverse voltage rating relative to the peak RF voltage levels in the intended circuit path.

RF Diode Part Context

This component belongs to Rohm's series of mold-type PIN diodes engineered for reliability in compact electronic devices. It serves as a modern replacement for older pin diode configurations, offering improved performance metrics in a smaller footprint compared to legacy SOD-723 variants while maintaining similar electrical characteristics.

RF Diode Replacement Considerations

The RN141G (SOD-723 package) is listed as a similar specification alternative. Designers should account for the physical size difference between the SOD-923 and SOD-723 packages when substituting components on existing PCB layouts.
