SMP1321 Series: Low Capacitance, Plastic Packaged PIN

Diodes

Applications

• High-performance wireless switches

Features

• Capacitance: 0.18 pF typical @ 30 V

• Series resistance: 1.05 Ω typical @ 10 mA

• Packages rated MSL1, 260 °C per JEDEC J-STD-020

Description

The SMP1321 series of plastic packaged, surface mountable PIN

diodes is designed for use in high volume switch applications from

10 MHz to more than 10 GHz. The low capacitance of these

diodes (0.25 pF), combined with a low resistance (2.0 Ω

maximum at 10 mA), makes the SMP1321 series particularly

suited to high isolation, series-connected PIN diode switches in

battery operated circuits.

The SMP1321 series is available in a selection of plastic packages

and a variety of configurations that include an SC-70, a small

footprint SC-79, a low inductance SOT-23, and a miniature

SOD-882.

Table 1 describes the various packages and marking of the

SMP1321 series.

SMP1321-007

For the -007 configuration of the SOT-23 package, the package

inductance is effectively reduced to 0.4 nH compared to the

1.5 nH value of the standard configuration. This lower inductance

is particularly beneficial when the diodes are used as shunt

connected switches at frequencies higher than 500 MHz in which

inductance is the primary limitation on maximum switch isolation.

To achieve the effective 0.4 nH, the SOT-23 package 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,

this low inductance feature is realizable only with the cathode

connected to ground.

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 SMP1321 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.

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

SMP1321 series PIN diodes are Class 1A ESD devices.
