TVS-Diodes, or Transient Voltage Suppression Diodes, are electronic devices designed to protect sensitive components and circuits from voltage and current transients. One of the most popular and commonly used models is the 3KASMC24AHM3_B/I, which is designed to protect circuits from over-voltage and over-current conditions. This article will discuss the application field and working principles of the 3KASMC24AHM3_B/I, and other related information.

Application Field

The 3KASMC24AHM3_B/I is designed for use in a wide range of applications. It can be used in consumer electronics such as multimedia devices, digital cameras, laptops, and other portable electronic devices. Additionally, it can be used in industrial applications such as automation equipment, and automotive components such as fuel pumps, ignition systems, and other voltage dependent device. It is also suitable for use in telecom and computer networks. In all of these applications, the 3KASMC24AHM3_B/I provides voltage and current transient protection.

Working Principle

The 3KASMC24AHM3_B/I works by providing a low resistive path from the power supply to the ground when the voltage exceeds a certain level or if the current exceeds a certain level. It consists of a pair of Silicon Avalanche Diodes (SAD) that are connected in series, providing a diode protection that can handle large overloads. When the design voltage of the TVS is exceeded, the SADs begin to conduct and allow the current to pass through to the ground, allowing the voltage to return to its normal level.

In addition to providing protection against voltage and current transients, the 3KASMC24AHM3_B/I also features over-voltage protection. This works by reducing the voltage in the circuit when it exceeds a certain level, providing protection against accidental damage to components or circuits.

Package Options

The 3KASMC24AHM3_B/I is available in two package styles, both of which are thermal-resistant and offer low thermal resistance. The first is the SMT (surface mount) package, which is designed to be easily integrated with surface mount equipment and can be adapted for use in reflow soldering or vapor phase soldering. The second is the through-hole package, which is designed to be mounted to a printed circuit board (PCB). Both packages are lead-free, providing better reliability and improved quality control.

Conclusion

The 3KASMC24AHM3_B/I is a popular and commonly used TVS diode that provides protection against voltage and current transients. This makes it suitable for use in a wide range of applications, from consumer electronics to industrial and automotive applications. It features over-voltage protection and comes in two package styles, surface mount and through-hole, providing design flexibility and reliability.
