The 3KASMC16AHE3/57T provides excellent reliable surge protection from over-voltage transients, reverse polarity, and ESD. Its compact size makes it very suitable for the protection of low-voltage applications, including industrial and consumer electronics as well as automotive electronics.

Working Principle

3KASMC16AHE3/57T is a TVS diode, which uses a Zener diode in order to protect circuits from excessive voltage. The diode is constructed from a silicon substrate, and the voltage breakdown process requires a Zener diode. The Zener diode will start to conduct electric current when the voltage across the diode exceeds a certain value, known as the breakdown voltage (Vz). The operating voltage of 3KASMC16AHE3/57T is 18V, and it has a maximum current running through it of 400mA. Its high surge capability allows it to protect against a wide range of over-voltage and transients, making it suitable for a wide variety of industrial and consumer applications.In order to ensure a safe and reliable operation, the circuit of 3KASMC16AHE3/57T must be designed to maintain the breakdown voltage (Vz) under the maximum allowed operating voltage (Vmax). This can be done by reducing the resistance in the circuit, which will limit the current passing through the diode. Additionally, the voltage across the diode must not exceed Vmax by more than 5%, otherwise the diode may be damaged.

In summary, 3KASMC16AHE3/57T is an ideal TVS diode for a variety of applications that require surge protection. Its compact size and high surge capability make it suitable for low-voltage applications, providing reliable protection from over-voltage and transients. When designing a circuit with 3KASMC16AHE3/57T, it is important to ensure that the circuit is designed to maintain the breakdown voltage at or below the maximum operating voltage in order to ensure a safe and reliable operation.
