3KASMC18AHM3_B/I

The 3KASMC18AHM3_B/I belongs to the TVS-Diodes, which are designed to aid in the protection of sensitive electronics. TVS-Diodes are semiconductor devices most commonly used to protect devices from electrostatic discharge, or ESD. It also helps in slowing down transient voltages and assisting “varistors” in limiting peak voltage in a circuit application.

Overview

The 3KASMC18AHM3_B/I is a two-line protection TVS-Diode which is designed to protect against ESD to IEC 61000-4-2 Level 4 ±8kV / ±15kV (air/contact discharge) or Transient Voltage Surge according to IEC 61000-4-5 / 10/700µs and voltage peaks up to 1500V. It provides superior protection for general industrial electronics, consumer electronics, automotive electronics, medical electronics, telecom/datacom applications. It is multiline and multimode protection device suitable for high speed data lines and working with very low leakage current at high peak power.

Application Field and Working Principle

Most commonly used applications are in power switching equipment, computer and telecommunication systems, and also power supply lines, automotive systems, medical devices, and consumer electronics. The 3KASMC18AHM3_B/I allows designers to effectively reduce preventable equipment losses due to transient surges and ESD. This driver line diode offers protection at the most common voltage levels up to 1500V and also work across higher frequencies. It utilizes series connected semiconductor devices such as ultra low capacitance varistors, SCRs, diodes, thyristors, and transzorbs to control the current in a circuit.

In terms of working principle, the 3KASMC18AHM3_B/I utilizes a series of semiconductor devices to use the power of its capacitance to control the transient voltage. In a circuit, these devices form a bridge between the local power line and the protected line. When a transient voltage or ESD occurs, the voltage is regulated by the power of the capacitances and limited to a safe level. Without the use of TVS-Diodes, the transient voltage would not be limited in this way and could damage the circuits.

The 3KASMC18AHM3_B/I is designed to provide an extremely fast and reliable line of defense against the damages that can be caused by transients and ESD. The device also utilizes a full coverage of protection modes with a broad range of operating frequencies, allowing designers to optimize the performance to a wide variety of applications. The combination of both transient protection and ESD protection helps to ensure that the sensitive electronics continue to function properly.

Conclusion

The 3KASMC18AHM3_B/I is an effective way to protect sensitive electronics from ESD and transient voltages. The device utilizes a series of semiconductor devices to limit the voltage to a safe level and ensure that the circuit is protected from any potential issues. Its wide range of operating frequencies and protection modes allows designers to optimize the performance for their particular applications. By utilizing this protection device, designers can be sure that their electronics will be safe in the long run.
