DATA SHEET 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 Skyworks GreenTM products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of GreenTM, document number SQ04–0074. 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 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.

Tin/lead (Sn/Pb) packaging is not recommended for new designs. SMP1321-007 Electrical and Mechanical Specifications 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. The part number and configuration for the SMP1321 series are provided in Table 1. The absolute maximum ratings of the SMP1321 series are provided in Table 2. Electrical specifications are provided in Table 3. Resistance versus temperature measurements are provided in Table 4. 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. Gap Typical performance characteristics of the SMP1321 series are illustrated in Figures 2 to 5. Package Dimensions Package dimensions are shown in Figures 6 to 10 (even numbers), and tape and reel dimensions are provided in Figures 7 to 11 (odd numbers). Package and Handling Information Ground S1650 Figure 1. SOT-23 Package Trace Gap 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.

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.
