TVS (Transient Voltage Suppressor) diodes, such as the 5KP120AHE3/73 diode, are designed to protect sensitive electronic equipment from electrical surges, most notably those caused by lightning strikes, electrostatic discharge (ESD), and other transient voltage events.

The 5KP120AHE3/73 diode is specifically designed to safeguard equipment from transient voltage-induced damage; this makes it suitable for a wide range of applications. It has the capacity to clamp voltages up to a peak current of 12kA, making it suitable for protecting equipment from large transient events such as lightning strikes. It has a response time of 1 nanosecond, meaning it can quickly clamp transient events and protect sensitive equipment. Additionally, it can be used to protect equipment from ESD events, which is essential for any electronic equipment being used in high-temperature environments.

The working principle of the 5KP120AHE3/73 diode is based on a standard diode rectifier. A diode is a one-way valve that only allows current to pass through in one direction, while blocking current in the opposite direction. When an incoming voltage exceeds the breakdown voltage of the diode, the diode will begin to conduct current. This causes a change in the voltage level, known as the breakdown voltage, which sets the start of the clamping action.

When the breakdown voltage is reached, the diode begins to conduct current and the voltage across the diode drops. When the transient voltage reaches the peak, the voltage across the diode drops to the maximum holding voltage. When the transient voltage falls below the breakdown voltage the diode resumes its non-conducting, non-latching, behavior. This allows it to clamp transient surges and protect sensitive electronic equipment from voltage-induced damage.

The 5KP120AHE3/73 diode is an ideal choice for protecting sensitive equipment from transient surge events, ESD, and other transient voltage events. It has the capacity to clamp voltages up to a peak current of 12kA, a response time of 1 nanosecond, and a maximum holding voltage of 1200V. It can be used to protect a wide range of equipment, from consumer electronics to industrial equipment, in environments with high temperatures and high risk of ESD events.
