TVS – Diodes are a type of semiconductor protection device that works to protect a system from overvoltage conditions, such as electrostatic discharges and lightning. This article will take a look at the 5KASMC36AHM3_A/I application field and working principle.

The 5KASMC36AHM3_A/I is a low-capacitance unidirectional transil designed to protect sensitive components from overvoltage transients. It is specifically designed for applications such as high-speed video interfaces (HDMI, DVI, or Card Readers) and Ethernet ports in which high data rates need to be maintained while providing maximum protection. The 5KASMC36AHM3_A/I is also capable of handling peak currents up to 5 A.

This component offers superior protection compared to other transil solutions due to its use of advanced breakdown technology, tight voltage distribution, and low capacitance, which reduces ringing or signal integrity issues. Furthermore, this device features an integrated resistor network that provides minimal output capacitance (0.6 pF typical), a low clamping voltage (13.5 V typical), and low leakage current (1 µA typical).

The 5KASMC36AHM3_A/I is composed of two monolithic integrated circuits that work together to provide complete protection against overvoltage transients. The first part of the circuit is the active element, which is composed of a voltage clamp and an ionization (avalanche) diode. This element works by clamping the surge voltage when it exceeds a certain level, and then redirecting the current to ground. The other element is a bypass diode, which allows for a low voltage path to ground for any remaining surge current.

When subjected to a surge voltage, the active element of the 5KASMC36AHM3_A/I will clamp the voltage and redirect the current to ground. This protects the circuit from being damaged by overvoltage transients. The bypass diode ensures that any residual current is directed safely away from the circuit, allowing it to remain protected from damage.

The 5KASMC36AHM3_A/I is designed to provide effective protection for a variety of applications. It is suitable for use in high-speed data interfaces and Ethernet ports, as well as in automotive and avionics applications. It is also designed to provide superior protection from electrostatic discharge (ESD) and lightning. This makes it ideal for use in sensitive areas, such as medical or military applications.

In summary, the 5KASMC36AHM3_A/I is a low capacitance unidirectional transil designed for use in applications which require high levels of protection against overvoltage transients, such as ESD and lightning. It works by clamping the surge voltage and redirecting the current to ground, while a bypass diode ensures that any residual current is safely directed away from the circuit. This makes it suitable for use in a variety of applications, from high-speed data interfaces to automotive and avionics.
