3KASMC12HE3/57T

The TVS - Diodes designation 3KASMC12HE3/57T is a low capacitance bi-directional ESD protection device commonly used in communication and A/V systems. It is consists of two transient voltage suppressors (TVS) or Zener diodes, which act as surge arresters to protect data lines from transients, ESD, and other over-voltage conditions potentially encountered in the operating environment.

The 3KASMC12HE3/57T is a surface-mount device (SMD) that offers extra line-to-line and line-to-ground overvoltage protection. The ability of the 3KASMC12HE3/57T to protect data lines from spikes and surges ensures that the system or devices maintain the performance specifications and remain in safe operation. These devices with a wide variety of automotive environment applications also feature low capacitance, which extends their range of protection to signals up to 10MHz.

Application field of 3KASMC12HE3/57T

The 3KASMC12HE3/57T are widely used in communication and A/V systems for low capacitance and robust protection from overvoltage, ESD, and other transients. The 3KASMC12HE3/57T provide two lines of protection for communication systems, including: Ethernet, fiber optics, PCMCIA, USART, UART, and many other synchronization, data, and signal lines of industrial standards RS-232, RS-485, and I2C.

The 3KASMC12HE3/57T can also be used in other applications such as consumer electronics, medical systems, military systems and automotive applications. With their low capacitance and high ESD and EFT rating, these devices are suited for a variety of automotive environment applications, including ESLR (Electrostatic Sensitive Load Resistance) protection for Automotive Network or CAN bus lines, as well as protection for interior light power lines.

Working principle of 3KASMC12HE3/57T

The TVS - Diodes 3KASMC12HE3/57T use a low capacitance bi-directional ESD protection device, which consists of two diode structures. When an ESD, EFT or other transient voltage spike occurs, the two diodes perform like a valve opening between two lines. This opens the circuit and diverts the surge, thus providing protection to the device or system. The mix of two diodes enables this system to protect one line from the other, eliminating cross-talk and disturbances.

The 3KASMC12HE3/57T is designed to provide a low impedance path during a transient event, so it can absorb high surge current without sacrificing its protective attributes. To ensure robust protection even in extreme temperature or environmental conditions, the 3KASMC12HE3/57T also features a wide operating temperature range (from -55°C to 130°C).

TVS - Diodes 3KASMC12HE3/57T are a high-performance solution, and their ability to provide efficient protection from common transients, ESD, and other over voltage conditions protect the system or devices from a variety of environmental conditions.
