A transient voltage suppressor diode, also known as a TVS diode, is a type of diode designed to protect electronics by absorbing short-term, high-intensity surges in voltage. In particular, the 1.5KE62AE3/TR13, a unidirectional TVS diode, is used to protect against voltage transients caused by externally or internally induced events such as lightning, inductive switching operations, and even the switching of multiple components on the same circuit.

The 1.5KE62AE3/TR13 is a designed specifically for industrial and professional electronics, in fields such as medical, telecommunications, automotive, and control systems. Its features include a 5.2V maximum peak pulse power and a 10W peak pulse power dissipation, making it capable of suppressing voltage surges of up to 400 volts. It is also known for its clamping capabilities, which provide protection against over-voltage, while its low on-state resistance (typically 0.9Ω) ensures low power dissipation.

The working principle of the 1.5KE62AE3/TR13 is based on the reverse biased nature of the diode. When a surge is encountered, the diode conducts and the voltage is dropped across the diode. This voltage protection prevents the component from exceeding its operational voltage and causing damage or failure. The device also has a positive temperature coefficient (PTC) that helps protect the device from thermal runaway caused by excessive currents. In this case, the PTC rapidly increases the resistance in the diode to dissipate the current.

Aside from the 1.5KE62AE3/TR13, some of the other TVS diodes available to protect electronics include the 1.5KE120A, 1.5KE150A, and ESD2T470WC parts. Each of these parts has specific features that make it suitable for different applications. For example, the 1.5KE120A is able to handle a maximum pulse power of 6.8V and is designed for industrial, medical, and automotive applications. The 1.5KE150A is designed for telecommunications applications and can handle a maximum pulse power of 8.8V.

The 1.5KE62AE3/TR13 and other TVS diodes offer industrial and professional electronics with effective protection from voltage transients caused by high-voltage surge events. With their ability to absorb short-term, high-intensity voltage surges, these parts can save equipment from damage, extend component life, and improve system reliability.
