RN142STE61

RF Diode Overview

The RN142STE61 is a PIN diode manufactured by ROHM Semiconductor, designed for RF switching and attenuation applications. It features a single configuration within an SOD-523 package (JEITA SC-79), measuring 1.6x0.8 mm with a thickness of 0.7 mm. Key electrical parameters include a reverse voltage (Vr) of 60 V, a forward current (If) of 100 mA, and a junction temperature (Tj) rating of 150 °C. The device exhibits a capacitance (Ct) of 0.45 pF at 1 V reverse bias and 1 MHz, with a series resistance (Rf) of 3.0 Ω at 100 mA forward current.

RF Diode Feature Summary

• Utilizes a compact SOD-523 surface-mount package to minimize board space requirements.
• Provides low capacitance characteristics suitable for high-frequency RF signal handling.

RF Diode Applications

• RF switching circuits
• Variable attenuators

RF Diode Procurement Notes

Verify the specific ordering suffix STE61 against official documentation to confirm tape-and-reel packaging details. Ensure compatibility with existing BOMs as this component may be subject to lifecycle changes or end-of-life status depending on regional availability.

RF Diode Selection Notes

Select this part when a small footprint PIN diode with 60 V reverse voltage capability is required. Confirm that the 0.45 pF capacitance meets the specific frequency response needs of the target RF application.

RF Diode Part Context

This component belongs to ROHM's PIN diode family, specifically engineered for radio frequency applications. The RN142S series offers a balance of low capacitance and moderate power handling in a miniature form factor.

RF Diode Replacement Considerations

The RN142SM is listed as a similar level replacement with the same pinout and package. Verify if the RN142SMT2R variant meets specific reel quantity requirements before substitution.
