Variable Capacitance (Varicaps, Varactors) diodes are a type of semiconductor device that has a reverse biased voltage across two electrode terminals. Due to the junction capacitance of the two electrodes, the device exhibits a variation in capacitance when its reverse bias voltage is varied. This is known as the capacitance-voltage (C-V) curve. The ZMV934ATC is a Varicap which features high Q and stable performance, which makes it well suited for a variety of applications.

The ZMV934ATC is a three lead variable N-channel MOSFET-P type Varicap diode with a built-in reverse bias regulator. This Varicap features a low forward voltage drop and a low reverse leakage current. The ZMV934ATC is available in a variety of capacitance values, ranging from 0.15pF to 50pF.

The ZMV934ATC is primarily used in applications where a variable capacitance is required. These applications include filters, passive audio crossover networks, AM and FM tuners, oscillators, and amplifiers. The device can also be used in systems requiring low phase and amplitude noise.

To understand the working principle of the ZMV934ATC, we must first understand the concept of junction capacitance. When a reverse bias voltage is applied across two excessively doped regions, the charge carriers form a depletion layer that is capable of storing charge. This stored charge forms the junction capacitance, which is the ratio of the stored electric charge to the applied reverse bias voltage.

The capacitance of the diode is dependent on the voltage applied across the two regions, as well as the doping level used in the manufacture of the semiconductor material. The ZMV934ATC features a built-in regulator which alters the reverse bias voltage of the diode, and hence its capacitance. By varying the reverse bias voltage, the capacitance of the diode can be accurately adjusted within the range specified by the manufacturer.

The ZMV934ATC is well suited to a wide range of applications due to its low forward voltage drop, low reverse leakage current, and stable capacitance. It can be used in a variety of filters, passive audio crossover networks, AM and FM tuners, oscillators, and amplifiers, making it a versatile and efficient device.
