TVS - Diodes are semiconductor devices used in many different electrical and mechanical environments to protect circuits from high voltage transients. The P4KA36HE3/54 is one such device. It is a 500W, 5.0 kV bidirectional Transient Voltage Suppression Diode made by Littelfuse, suitable for various applications.

The P4KA36HE3/54 is a surface mount device, designed to fit a TO-220AB package. It is designed to dissipate a high level of energy, allowing for bidirectional applications, and includes a guard ring design which reduces leakage current and increases surge capability.

The TVS diode protects against negative transients ranging from -30 V to -5.0 kV, and positive transients ranging from 10 V to 5.0 kV. High surge current is also supported, with single discrete short-term pulses up to 1 kA peak for 10/1000 μs waves. The breakout voltage for the P4KA36HE3/54 is approximately 7 V.

Because of its wide range of ratings, the P4KA36HE3/54 is well-suited for many different applications. It can be used to protect automotive electrical systems from the high level of heat and current transients that occur during peak periods. It can also be used to protect industrial control systems and medical equipment and in power systems. In addition, it can be used to protect circuits in computers, servers, telecom systems, and other consumer electronics.

The working principle of the P4KA36HE3/54 is based on the concept of reverse conduction. In the presence of a transient voltage surge, the diode will pass current from anode to cathode in the reverse direction. This will cause the breakdown voltage of the diode to be exceeded and clamp the voltage at a safe level for the protected circuit. The amount of current that is passed will depend on the amplitude and duration of the surge. The diode will also act to limit peak current and reduce the peak voltage of the transient.

The P4KA36HE3/54 can be used in a variety of different applications to protect circuits from the damaging effects of high voltage transients. It can be used in automotive, industrial, power, and consumer electronics applications to protect circuits from damage. Additionally, its wide range of ratings makes it suitable for many different applications, including those in which there is a need to protect circuits from both positive and negative transient voltages.
