The SMV1235-011 from Alpha Components is a silicon hyperabrupt junction varactor diode. It is designed for use in Voltage Controlled Oscillators (VCOs) requiring low tuning voltage operation. The low series resistance of this varactor makes it suitable for high Q resonators in wireless system VCOs operating at frequencies beyond 2.5 GHz.
Key electrical specifications include a capacitance of 10.35 pF at 1V, 6.4 pF at 3V, and 3.6 pF at 6V. The capacitance ratio (C1V/C3V) is typically 1.8, and (C1V/C6V) is typically 3.1. It features a low series resistance of 0.6 Ω at 500 MHz and 3V, contributing to low phase noise. The typical quality factor (Q) at 50 MHz is 750.
This varactor diode has a maximum forward current of 20 mA and a maximum power dissipation of 250 mW. It operates within a temperature range of -55 °C to +125 °C and has a storage temperature range of -55 °C to +150 °C. The device is protected against electrostatic discharge with an ESD human body model rating of Class 1B.
The SMV1235-011 is supplied in a surface-mount SC-70 package. It is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
