SMP1304 Series: Low-Distortion Attenuator Plastic
Packaged PIN Diodes
Applications
• TV distribution
• Attenuator circuits
Features
• Low-distortion design
• Frequency range from 5 MHz to >2 GHz
• Designed for base station applications
• Configured for PI and TEE attenuators
• Packages rated MSL1 @ 260 °C per JEDEC J-STD-020
Description
The SMP1304 series of plastic packaged, surface mountable, low
capacitance (0.3 pF) silicon PIN diodes is designed for attenuator
applications from 5 MHz to beyond 2 GHz.
The thick 100 μm I region of these PIN diodes makes them very
attractive for use in low-distortion PI and TEE attenuators
commonly found in TV distribution applications.
The 1 μs typical carrier lifetime of these diodes results in a
resistance of 20 Ω maximum at 1 mA and 7 Ω maximum at
10 mA.
The SMP1304 series is available in a selection of plastic
packages: as a single diode in small footprint SOD-323 and SC-79
packages, and in a variety of configurations in an SOT-23
package, including the low inductance (0.4 nH) SMP1304-007.
The SMP1304-019, a three-diode junction designed for insertion
in PI attenuators, is available in an SOT-143 package. The
SMP1304-027 is available in an SOT-5 package as a four-diode
array designed for insertion in commonly used four-diode PI
attenuator circuits.
Table 1 describes the various packages and marking of the
SMP1304 series.

SMP1304-007
The inductance of the SMP1304-007 is effectively reduced to
0.4 nH compared to the 1.5 nH of the standard configuration. The
lower inductance is particularly beneficial when the diodes are
used as shunt-connected switches at frequencies >500 MHz
where inductance is the primary limitation on maximum switch
isolation.
To achieve the effective 0.4 nH, the SMP1304-007 must be
inserted in the microstrip circuit board with a gap in the trace as
shown in Figure 1. Because of the polarity of the diode junction,
the low inductance can only be achieved with the cathode
connected to ground.

Figure 2. SMP1304-019 Package (PI)
SMP1304-019 PI Attenuator PIN Diodes
The SMP1304-019 uses three PIN diode junctions in an SOT-143
package (see Figure 2). The junctions are configured for ease of
insertion in PI attenuator circuits in common use from 10 MHz to
>1 GHz. The SMP1304-019 PIN diode junction was designed for
low capacitance, a wide resistance dynamic range, and low
distortion performance.

Note: 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
SMP1304 series PIN diodes are Class 1C ESD devices.
