1.5SMC120A-E3/57T

This article will discuss the application field and working principle of 1.5SMC120A-E3/57T, which is in the family of TVS - Diodes. A TVS - Diode, or Transient Voltage Suppressor Diode, is designed to protect sensitive electrical componentry from unexpected high voltage transients. This family of diodes is designed to protect circuits from destruction caused by electrical transients with high peak pulse power.

A 1.5SMC120A-E3/57T is a TVS- diode composed of three components -- two diodes and a thyristor device. It provides positive and negative overvoltage protection to a voltage range of -1.5V to +120V. The device prevents collateral damage to the circuit from destructive overvoltage levels and will clamp the voltage to prevent further damage. The diode, which is also in the family of TVS- diodes, has a surge rating of 57A and is capable of handling a peak pulse power of 1.5 kV.

The working principle behind 1.5SMC120A-E3/57T is fairly simple. During normal electrical events, the diode will remain open circuited. However, when a high voltage transient occurs, the diode will be triggered and will clamp the voltage. This is done by actuating the thyristor device, which in turn will supply a path of current to the circuit, thus bringing the voltage back to its initial states.

1.5SMC120A-E3/57T is commonly used in various electronic circuits, such as car charging systems, power supplies, and communication equipment. It is also commonly found in consumer consumer electronics devices, such as headphones, cell phones, and laptops. The diode\'s high surge rating and its capability to handle high peak pulse current make it a popular choice for such applications.

Overall, 1.5SMC120A-E3/57T is a popular choice for protecting sensitive electrical componentry from unexpected high voltage transients. It is composed of two diodes and a thyristor device which provides positive and negative overvoltage protection and can handle a peak pulse power of 1.5 kV. The diode is commonly found in car charging systems, power supplies, communication equipment, and consumer consumer electronics devices.
