SMP1302-011LF

RF Diode Overview

The SMP1302-011LF is a single, plastic-packaged silicon PIN diode from the Skyworks SMP1302 series. It utilizes an SOD-323 package with a specified parasitic inductance of 1.5 nH. The device features a nominal 50 μm I-region width and supports a maximum reverse voltage of 200 V. Electrical characteristics include a capacitance of 0.3 pF at 30 V reverse bias and a forward voltage of 0.8 V at 10 mA drive current. Series resistance varies from 15 Ω at 1 mA to 1.5 Ω at 100 mA at 100 MHz. The component operates within a temperature range of -65 °C to +150 °C.

RF Diode Feature Summary

• Low-distortion design optimized for high-volume switch and attenuator applications
• Suitable for low-drive TEE attenuators and large-signal switching circuits
• Rated for lead-free soldering with Moisture Sensitivity Level 1 (MSL1) classification

RF Diode Applications

• Cellular base stations
• High-volume RF switches
• TEE attenuators

RF Diode Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm package type and marking codes. Confirm RoHS compliance status via the manufacturer's Certificate of Conformance prior to procurement. Ensure ESD handling precautions are strictly followed during storage and assembly to prevent damage to the semiconductor junction.

RF Diode Selection Notes

Select this component when a single-diode configuration in an SOD-323 package is required. The 1.5 nH inductance specification makes it suitable for frequencies extending beyond 10 GHz. Evaluate the 50 μm I-region width for compatibility with large-signal switching requirements compared to lower-resistance variants.

RF Diode Part Context

This part belongs to the SMP1302 series, which encompasses single, dual, and quad configurations across multiple packages including SOT-23, SC-79, SC-88, and SOD-882. The SMP1302-011LF specifically denotes the single common-anode variant housed in the SOD-323 footprint.
