Description
The SMP1302 series of plastic packaged, surface mountable, low
capacitance (0.3 pF) silicon PIN diodes is designed for highvolume switch and attenuator applications from 10 MHz to
beyond 10 GHz.
These diodes are designed for use in low-distortion TEE
attenuators with low drive current (maximum resistance at 1 mA
is 10 Ω) commonly used in TV distribution and cellular base
station applications. The nominal 50 μm I region width, combined
with a maximum resistance of 3 Ω at 10 mA, makes these diodes
useful in large signal switch applications.
The SMP1302 series provides single, dual, and quad diodes in a
selection of plastic packages including SOT-23, SOD-323, SC-79,
SC-88, and a small footprint SOD-882.
Table 1 describes the various packages and marking of the
SMP1302 series.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.

Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMP1302 series is rated to Moisture Sensitivity Level 1
(MSL1) at 260 C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
