Description The SMV1275-079LF is a silicon hyperabrupt junction varactor diode specifically designed for battery operation. The specified high-capacitance ratio and low-series resistance make this varactor appropriate for low phase-noise Voltage-Controlled Oscillators (VCOs) used at frequencies in wireless systems up to and above 2.5 GHz. Applications for the SMV1275-079LF include low-noise and wideband UHF and VHF VCOs for GSM, PCS, CDMA, and analog phones. Table 1 describes the packaging and marking of the SMV1275-079LF varactor. Table 1. Packaging and Marking Single SC-79 Green™ SMV1275-079LF Marking: Cathode and Y6 LS = 0.7 nH The Pb-free symbol or “LF” in the part number denotes a lead-free, RoHScompliant package unless otherwise noted as Green™. Tin/lead (Sn/Pb) packaging is not recommended for new designs.

Electrical specifications are provided in Table 3. Typical capacitance values are listed in Table 4. The relationship between capacitance and reverse voltage is illustrated in Figure 1. 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 SPICE model for the SMV1275-079LF varactor is shown in Figure 2 and the associated model parameters are provided in Table 5. The SMV1275-079LF varactor 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. Package dimensions are shown in Figure 3, and tape and reel dimensions are provided in Figure 4. 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. Table 2. SMV1275-079LF Absolute Maximum Ratings (Note 1) Parameter Symbol Minimum Typical Maximum Units 10 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 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.
