TVS diodes (transzorb, transient voltage suppressor) are a type of surge protection semiconductor device that protects sensitive electronic circuits from excessive voltage transients overvoltage. Varistors, MOVs, or TVS diodes consist of a diode or the junction of diode-connected transistors, usually connected in parallel with a resistor and capacitor, to provide a low impedance path for high voltage spikes, electrostatic discharges, or electrical transients above the TVS clamping voltage. The V120ZT6P device is a radial-leaded, bi-directional, transient voltage suppressor (TVS) diode designed to protect electronic components and equipment from harmful electrical transients.

The V120ZT6P provides superior surge capability of 120 volts, and at a wide range of operating temperatures from - 55°C to 150°C. A common application of the V120ZT6P is in industrial machinery, electric equipment, and automotive electronics, where high voltage transients must be prevented from damaging delicate electronic components and circuits. In addition, the V120ZT6P is also suitable for applications in general consumer electronics and telecommunications.

Working principle of the V120ZT6P: as the device is connected into a circuit, it is configured to forward bias and provides a low impedance path for capacitively coupled transients across its terminals. In this mode, the device acts as a short circuit, dissipating the transient energy in the form of heat. Thus, the V120ZT6P quickly absorbs and then suppresses low-level transients and any residual voltage in the circuitry is limited to its clamping voltage.

The V120ZT6P also features an internal diode and resistor network which enables the device to absorb high energy transients without limiting peak current to its terminals. This means the V120ZT6P can absorb even large transient spikes and protect the downstream electronic components from damage. In addition, the internal diode enables the device to act as an ESD protection component, and the resistor network ensures that it does not damage sensitive devices during high power applications.

The combination of a fast transient response, wide operating temperature range, and high ESD protection makes the V120ZT6P ideally suited for applications that require maximum protection from high voltage transients, ESD, and other power-related events. It is well-suited for use in automotive, industrial, consumer electronics, and telecommunications applications, providing reliable circuit protection for sensitive components and circuits. The V120ZT6P is available in both TO-220 and SMD packaging for easy integration into high-density circuit boards.
