SMP1334-084LF

RF Diode Overview

The SMP1334-084LF is a surface-mountable, low-capacitance silicon PIN diode designed for high-power applications from 10 MHz to beyond 6 GHz. It features a nominal 50 μm I-region width and operates with a forward current of up to 200 mA and reverse voltage of 200 V. The device dissipates 1 W at 85 °C and handles 100 W CW in series-connected transmit/receive switches. Electrical specifications include a maximum total capacitance of 0.45 pF at 30 V and typical series resistance values of 16.5 Ω at 1 mA, 2.0 Ω at 10 mA, and 0.45 Ω at 100 mA (100 MHz). It utilizes a small QFN (2 x 2 mm) package.

RF Diode Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to ensure correct packaging and compliance status. Confirm that the component meets Moisture Sensitivity Level 1 (MSL1) requirements for lead-free soldering processes. Review absolute maximum ratings carefully to prevent permanent damage during assembly or operation.

RF Diode Selection Notes

Select this component when designing circuits requiring high power handling and low parasitic capacitance above 10 MHz. Ensure the design accommodates the 200 mA forward current limit and 200 V reverse voltage rating. Evaluate the 1 W dissipation power rating relative to the operating ambient temperature to maintain safe junction temperatures.
