ZMV933ATC

Diodes - Variable Capacitance (Varicaps, Varactors)

The ZMV933ATC is a type of Variable Capacitance (Varicap) Diode, an electronic component that utilises a voltage applied to its circuit to alter capacitance. Varicaps are most commonly available in an axial lead DO-7 package. It is a dual varactor diode that is used for tunable applications such asFM tuners and receivers, radio equipment, and audio applications.

Varicaps are based on the capacitance principles of conventional electronic diodes. When voltage is applied to the circuit, the PN junction alters its electrical characteristics and a negative resistance is observed. This effect then causes the two plates on either side of the PN junction to become more closely spaced, causing the effective capacitance of the varicap to increase. Conversely, when the applied voltage is removed, the plates retract, reducing the capacitance. This behaviour is of great use in certain electrical and electronic components and can be used to effectively control the size of capacitances in various circuits.

The ZMV933ATC model offers a wide setup range, with a default wide tuning range of 16.7 to 19.5 pF. It is designed with a maximum operating voltage of 30 Volts, and is intended for use in applications such as FM tuners, electronic oscillators, RF circuits, and in filter circuits, such as low pass and band stop filters. Thanks to its high linearity and low noise characteristics, it is most suitable for Impedance Tuning or Impedance Matching such as band-pass filters and high-quality radio receivers.

The ZMV933ATC has a good voltage coefficient, meaning that it can provide a stable capacitance value across a large voltage range. It is rated for a wide temperature range from -55°C to +125°C, which means that it is designed to work in extreme temperature conditions. The device is also rated to a maximum reverse bias of 10V, meaning that it can be used in high voltage and high current applications.

The ZMV933ATC is extremely useful in applications that require variable capacitance, such as FM tuners and receivers, radio equipment, and audio applications. It can also be used in filter circuits, as it provides excellent linearity and low noise characteristics. With its wide setup range, high linearity, low temperature coefficient, and wide operating temperature range, this Varicap diode offers the perfect balance between performance and reliability.

The ZMV933ATC Varicap diode is a valuable electronic component and its wide range of applications makes it a great choice for a wide variety of projects. With its stable capacitance value, low temperature coefficient, and wide operating temperature range, this Varicap diode is sure to be a valuable addition to any electronic circuit.
