DATA SHEET SMVA1470-004LF: Hyperabrupt Junction Tuning Varactor Automotive Applications Low-noise VCOs and VCXOs in wireless systems Infotainment Navigation Telematics Garage door openers Wireless control systems Description Features AEC-Q101 qualified ISO/TS16949 certified facility High capacitance ratio SOT-23 package (MSL1, 260 C per JEDEC J-STD-020) The SMVA1470-004LF is a dual silicon, hyperabrupt junction varactor diode in a common cathode configuration. The specified high capacitance ratio and low series resistance make this varactor appropriate for low-noise voltage controlled oscillators (VCOs) and voltage-controlled crystal oscillators (VCXOs) in wireless systems for in-vehicle infotainment applications. Table 1 describes the SMVA1470-004LF package and marking. Skyworks Green™ products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of Green™, document number SQ04-0074. Table 1. Package and Marking Common Cathode SOT-23 SMVA1470-004LF Green™ Marking: ET3 LS = 1.4 nH The Pb-free symbol or “LF” in the part number denotes a lead-free, RoHScompliant package unless otherwise noted as Green™.

SMVA1470-004LF Absolute Maximum Ratings (Note 1) Parameter Symbol Minimum Maximum Units 20 mA Forward current IF Power dissipation PD 250 mW Storage temperature TSTG –55 +150 C Operating temperature TA –55 +125 C Electrostatic discharge: ESD 1000 500 50 V V V Charged Device Model (CDM), Class 3 Human Body Model (HBM), Class 1A Machine Model (MM), Class A 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. 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.
