DATA SHEET SMV1771 Series: Hyperabrupt Junction Tuning Varactors Applications Low-noise and wideband UHF and VHF VCOs High-volume, low-cost battery-powered tuning circuits Features Low series resistance High capacitance ratio SC-79 and ultra-small SOD-882 packages (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 SMV1771 series are silicon hyperabrupt junction varactor diodes specifically designed for battery operation. The specified high capacitance ratio and low series resistance make these varactors appropriate for low phase noise Voltage-Controlled Oscillators (VCOs) used at frequencies in wireless systems up to and above 2.5 GHz. Table 1 describes the package and marking of the SMV1771 varactor series. Table 1. Packaging and Marking Single Single SC-79 Green™ SOD-882 Green™ SMV1771-079LF Marking: Cathode and YH SMV1771-040LF Marking: EL1 LS = 0.7 nH LS = 0.45 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 SMV1771 varactor series is shown in Figure 2 and the associated model parameters are provided in Table 5. The SMV1771 varactor series are rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. They 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 Figures 3 and 5, and tape and reel dimensions are provided in Figures 4 and 6. 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. SMV1771 Series 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 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.
