A Transient Voltage Suppression diode, better known as a TVS diode, is a vital piece of today’s modern technology. While they are quite common, many are unaware of their many uses and the importance they serve in the global marketplace. The 1.5KE91ATR is one such diode, and it is important to understand the application fields and working principles of this important device.

TVS diodes are designed to protect a circuit from overvoltage conditions, such as a short event or transients caused by lightning or other sources. They are available in different forms, and the 1.5KE91ATR is a single-line unidirectional diode. It is designed to provide protection for communication systems, which have high voltage transients. This diode is designed to protect the system from overvoltage rise, and it will shunt the excess current away from the circuit, preventing damage to the system. The 1.5KE91ATR is designed to be compatible with surface mount technology, providing a minimum foot print.

A TVS diode has several important components. It is composed of a PN junction, which is the heart of the diode. A PN junction is a semiconductor which can be formed by combining a P-type and N-type semiconductor material. When the junction is forward biased, electrons and holes will move towards each other and create a current flow. This current flow will increase exponentially until it reaches a point known as the avalanche breakdown voltage. The 1.5KE91ATR is designed to withstand a peak reverse voltage of 600 volts, and its avalanche breakdown voltage is 55 volts.

The working principles of a TVS diode are relatively simple. When a voltage spike occurs, the PN junction will experience a very high voltage. This voltage will be much higher than the breakdown voltage, and the diode will begin to conduct current. This current will help to shunt the excess voltage away from the circuit, and protect it from any damage.

The 1.5KE91ATR is designed to be used in automotive, computer and communication systems. Its small size and surface mount technology makes it an ideal choice for applications where space is at a premium. Its ability to handle a peak reverse voltage of 600 volts, combined with its low leakage current and low capacitance makes it ideal for use in high voltage applications. The TVS diode is designed to protect the system from overvoltage transients, and its small form factor makes it a great choice for applications where space is a premium.

TVS diodes are a vital piece of modern day technology, and the 1.5KE91ATR is an important component in many applications. Its ability to protect a circuit from overvoltage transients makes it a valuable tool in any system. It is important to understand the application fields and working principles of this device in order to determine its best possible use. By understanding how these diodes work, engineers can ensure that their systems are well protected from dangerous overvoltages.
