DATA SHEET SMV1231–SMV1237: Hyperabrupt Tuning Varactors Features High capacitance ratio Low series resistance for low phase noise ● Multiple packages SOT-23, SOD-323, SC-70 and SC-79 ● Designed for high-volume commercial applications ● Full characterization with SPICE models ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 ● ● Description The SMV1231–SMV1237 series of silicon hyperabrupt junction varactor diodes is designed for use in VCOs with low tuning voltage operation. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz. The SMV1231–SMV1237 series is fully characterized for capacitance and resistance over temperature. SPICE model is provided. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging. Absolute Maximum Ratings Characteristic Value Reverse voltage (VR) Forward current (IF) Power dissipation (PD) 15 V 20 mA 250 mW Storage temperature (TST) -55 °C to +150 °C Operating temperature (TOP) -55 °C to +125 °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 200058 Rev.
