DATA SHEET SMV1247–SMV1255: Hyperabrupt Tuning Varactors Features Designed for high volume commercial applications High capacitance ratio, C0.3 V/C4.7 V = 12 typ. ● Multiple packages SOT-23, SOD-323, SC-70 and SC-79 ● Available lead (Pb)-free MSL-1 @ 250 °C per JEDEC J-STD-020 ● SPICE models are available ● Available in tape and reel packaging ● ● Description The SMV1247–SMV1255 series of silicon hyperabrupt junction varactor diodes are designed for use in VCOs with low tuning voltage operation. This family of varactors is characterized for capacitance and resistance over temperature. SPICE models are provided. NEW Skyworks offers lead (Pb)-free “environmentally friendly” packaging that is RoHS compliant (European Parliament for the Restriction of Hazardous Substances). Absolute Maximum Ratings Characteristic Reverse voltage (VR) Forward current (IF) Power dissipation (PD) Value 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 0 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, 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 must be employed at all times. Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 200061 Rev.
