DATA SHEET SMV1145-079LF: Hyperabrupt Junction Tuning Varactor Applications High volume commercial systems Features Frequency linear design Low series resistance Package is rated MSL1, 260 °C per JEDEC J-STD-020 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. Description The SMV1145-079LF silicon hyperabrupt junction varactor diode is specifically designed with an increasing gamma versus voltage characteristic. This results in improved voltage-controlled oscillator (VCO) frequency-voltage linearity compared to a conventional hyperabrupt junction varactor. The SMV1145-079LF varactor is characterized for capacitance and resistance over temperature. Table 1 describes the package and marking of the SMV1145-079LF varactor. Table 1. Packaging and Marking Single SC-79 Green™ SMV1145-079LF Marking: Cathode and 3H LS = 0.7 nH The Pb-free symbol or “LF” in the part number denotes a lead-free, RoHS-compliant package unless otherwise noted as Green™. Tin/lead (Sn/Pb) packaging is not recommended for new designs.

SMV1145-079LF Absolute Maximum Ratings (Note 1) Parameter Symbol Minimum Typical Maximum Units 12 V Reverse voltage VR Forward current IF 20 mA Power dissipation PDIS 250 mW Operating temperature TOP –55 +125 C Storage temperature TSTG –55 +150 C Electrostatic discharge: ESD < 250 V Human Body Model (HBM), Class 0 Note 1: 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.
