DATA SHEET SMP1321 Series: Low Capacitance, Plastic Packaged PIN Diodes Features ● ● ● ● Designed for high-performance wireless switch applications 0.25 pF capacitance specified Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 Available in tape and reel packaging Description The SMP1321 series of plastic packaged, surface mountable PIN diodes is designed for high-volume switch applications from 10 MHz to beyond 2 GHz. The low capacitance of these diodes, (0.25 pF) combined with its low resistance (2.0 Ω maximum at 10 mA) makes the SMP1321 series particularly suited to highisolation, series connected PIN diode switches in battery operated circuits. Available in a selection of plastic packages and in a variety of configurations including a low inductance (0.4 nH) SOT-23 (SMP1321-007), the small footprint SC-79 and the miniature SC-70. The SMP1321-508 has been specifically designed for WLAN 802.11 a, b, and g applications. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging. Absolute Maximum Ratings Characteristic Reverse voltage (VR) Power dissipation @ 25 °C lead temperature (PD) Value 100 V 250 mW Storage temperature (TST) -65 °C to +150 °C Operating temperature (TOP) -65 °C to +150 °C ESD human body model Class 1B Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) 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 must be employed at all times. Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 200048 Rev.

This lower inductance will be particularly beneficial when the diodes are used as shunt connected switches at frequencies higher than 500 MHz, where 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 the figure. Because of the polarity of the diode junction, this low Gap inductance feature is realizable only with the cathode connected to ground.
