SMV2023-011LF

Overview

The SMV2023-011LF is a silicon hyperabrupt junction tuning varactor diode from the SMV2019 to SMV2023 series, manufactured by Skyworks Solutions. It utilizes an SOD-323 package with a typical series inductance of 1.5 nH and features a common cathode configuration. The device operates within a reverse voltage range up to 22 V and supports forward currents up to 20 mA. Electrical specifications at 25 °C include a capacitance range of 4.40 pF to 5.40 pF at 4 V reverse bias, and 0.90 pF to 1.20 pF at 20 V reverse bias. The typical capacitance ratio (CT @ 4 V / CT @ 20 V) is 4.20, with a minimum quality factor of 500 at 4 V and 50 MHz.
