The P4KE160CHE3/73 TVS diode is a small signal transient voltage suppressor (TVS) that can effectively protect electronic equipment from damaging voltages. It is a unidirectional dual diode and is specifically designed to protect sensitive components against overvoltage transients such as spikes and voltage induced by electrostatic discharges (ESD).

The P4KE160CHE3/73 is a bidirectional, low-capacitance, low-clamping-voltage (VCL) TVS diode with a maximum reverse stand-off voltage of 160 volts, a reverse leakage current of 5 mA at a maximum voltage of 160V and a capacitance of 0.73pF. It is ideal for circuit-board protection, telecommunications and data applications that require superior protection and low capacitance. The combination of low capacitance and low-clamping voltage provide superior protection from high energy transients, lightning, ESD, and other potential threats.

This diode is employed within a wide variety of electronic equipment, including amplifiers and receivers, bypass capacitors, control panels, data processing systems, digital control circuits, distributed power supply circuits, fiber optics systems, large and small equipment, logic circuits, modems, networking systems, power supplies, signal conditioning systems, and switching applications. In addition to protecting devices against ElectroStatic Discharge (ESD), the P4KE160CHE3/73 can also be used to protect circuits from overvoltage and short-circuit events.

The P4KE160CHE3/73 operates by diverting any electrical current that exceeds the absolute maximum DC reverse breakdown voltage (VR) to a safe path to avoid damaging the protected circuit. The device works by clamping the input voltage to a predetermined voltage level. The breakdown voltage or the clamping voltage is determined by the zener voltage and is specified as the maximum working voltage in the data sheet. The breakdown voltage is also known as headroom voltage and the TVS diode\'s VCL has to be greater than the maximum voltage of the waveform.

The unidirectional diode of the P4KE160CHE3/73 TVS provides superior protection from overvoltage transients by clamping the voltage to a safe level. While the bidirectional diode further improves protection against ESD and overvoltage transients, the low-capacitance (0.73pF) provides superior isolation of high-speed signals. Additionally, the P4KE160CHE3/73\'s wide operating temperature range (-55°C to 150°C) makes it ideal for use in extreme temperatures.

In conclusion, the P4KE160CHE3/73 is a unidirectional, low-capacitance, low-clamping-voltage TVS diode designed for superior circuit protection from overvoltage transients, such as spikes and ESD, ranging from 5mA to 160V. It offers superior protection over high-speed signals due to its low capacitance rating and wide operating temperature range. It is employed in various electronic equipment, including amplifiers and receivers, bypass capacitors, control panels, data processing systems, digital control circuits, distributed power circuits, fiber optics systems, large and small equipment, logic circuits, modems, and networking systems.
