SMV1800-079LF

DATA SHEET SMV1800-079LF: Hyperabrupt Junction Tuning Varactor Applications • Satellite tuners • VCOs • Tuneable couplings Features • Cross to NXP’s BB181 • Low series resistance • High capacitance ratio • Ultra-small SC-79 package (MSL1, 260 °C per JEDEC J-STD-020) Description The SMV1800-079LF 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 SMV1800-079LF include low-noise and wideband UHF and VHF VCOs for GSM, PCS, CDMA, and analog phones. Table 1 describes the package and marking of the SMV1800-079LF varactor. Table 1. Packaging and Marking Single SC-79 Green™ SMV1800-079LF Marking: Cathode 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.

SMV1800-079LF Absolute Maximum Ratings Parameter Symbol Minimum Typical Maximum Units 30 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: 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. Attention: Observe Precautions for Handling Electrostatic Sensitive Devices ESD Man-Machine (MM) Model = 400 V (ClassC) ESD Human Body Model (HBM) = 8 kV (Class 3B) ESD Charged Device Model (CDM) = 2 kV (Class 4) Electrostatic Discharge (ESD) can damage this device, which must be protected from ESD at all times. 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.
