A TVS (Transient Voltage Suppressors) diode is a device used to protect electronic systems from voltage transients like voltage spikes and lightning induced surge events. TVS diodes are semiconductors with a zener diode connected in parallel with a parasitic pn diode. To better understand the application field and working principle of 3KASMC43HE3_A/H, one needs to understand the theory behind TVS diodes.

In simple terms, TVS diodes work by providing a path for current to flow in one direction, namely away from the protected device, if a voltage spike occurs. The key to understanding how TVS diodes work is to first understand what a parasitic pn diode is. A diode is a two-terminal electronic component, made of a semiconductor material, that allows current to flow in only one direction. A parasitic pn diode is essentially two pn junctions, one connected in forward bias (positive current) and one connected in reverse bias (negative current). Depending on the type of material used, the parasitic pn diode can be designed to activate at a certain voltage, allowing current to pass through the device.

The 3KASMC43HE3_A/H is a TVS diode with a parasitic pn junction designed to activate at a breakdown voltage of 33 Volts in order to provide protection for sensitive electronic systems. It also has a peak pulse power rating of 1500 Watts and a standoff voltage of 19 Volts. The TVS diode is designed to provide protection in a wide range of applications, such as telecommunications, consumer electronics, automotive, instrumentation and industrial electronics. It is also rated for an operating temperature range of -55°C to +150°C, making it suitable for a variety of applications.

When the voltage across the 3KASMC43HE3_A/H exceeds its breakdown voltage, the diode begins to conduct current, providing a path for the current to be diverted away from the protected device. The diode then remains in a low impedance state until the voltage drops back below the breakdown voltage. This provides maximum protection from spikes in voltage of short duration, ensuring that the system is not damaged by any overvoltage conditions.

In summary, the 3KASMC43HE3_A/H is an efficient TVS diode designed to provide protection for sensitive electronic systems from voltage transients such as voltage spikes and surge events. It is suitable for a variety of applications, from consumer electronics to automotive and industrial use. Its ability to provide a low impedance path for current allows it to provide maximum protection from overvoltage conditions of short duration.
