DATA SHEET SMV1206-079LF Hyperabrupt Junction Tuning Varactor Applications Wideband RF and microwave VCOs Features High tuning ratio Low series resistance Description Designed for high volume, low-cost applications The SMV1206-079LF is a surface mount varactor diode designed Ultra-small SC-79 package (MSL1, 260 C per for very low series resistance applications such as RF and JEDEC J-STD-020) microwave VCOs. The SC-79 packaging option is defined in Table 1. The absolute maximum ratings of the SMV1206-079LF varactor are provided in Table 2. Electrical specifications are specified in Table 3. Figure 1 shows the typical performance of capacitance versus reverse voltage. The SPICE model for the SMV1206-079LF is shown in Figure 2 and the associated model parameters are provided in Table 4. The relationship between voltage and capacitance for the SMV1206-079LF is shown in Table 5. Table 1. Packaging and Marking Single SC-79 Green SMV1206-079LF Marking: Cathode 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. Skyworks Solutions, Inc.

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. The SMV1206-079LF varactor is a Class 0 Human Body Model (HBM) ESD device. Table 3.
