Description
The SMP1302 series of plastic packaged, surface mountable, low
capacitance (0.3 pF) silicon PIN diodes is designed for high-
volume switch and attenuator applications from 10 MHz to
beyond 2 GHz.
These diodes are designed for use in low- distortion PI and 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 and dual diodes in a
selection of plastic packages including SOT-23, SOD-323, small
footprint SC-79, an ultralow inductance (0.2 nH) SOT-143
(SMP1302-017), and miniature SC-70.
A four-diode array is available in an SOT-5 package (SMP1302-
027) designed for insertion in the commonly used four-diode PI
attenuator circuits.
Table 1 describes the various packages and marking of the
SMP1302 series.

SMP1302-017: Low Inductance PIN Diode in
SOT-143 Package
The SMP1302-017 uses the SMP1302 PIN diode in a customized
SOT-143 plastic package designed for high performance in high-
frequency applications. Its effective inductance, based on the
3 GHz isolation, is <0.2 nH. The SOT-143 package is diagrammed
in Figure 1.

Typical performance characteristics of the SMP1302 series are
illustrated in Figures 2 to 5. Package dimensions are shown in
Figures 6 to 11.
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.

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.
CAUTION:
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. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. The
SMP1302 series PIN diodes are Class 1C ESD devices.
