SA20HE3/54

Transient Voltage Suppression (TVS) diodes are popularly known as surge protectors, which protect electronic circuits from voltage spikes. The SA20HE3/54 is one such device that is specially used in communication applications like Ethernet, USB, and HDMI, among others. It is a bi-directional surge protector with dual elements, an epoxy case, and a plastic secondary sleeve.

This component is composed of two silicon diodes connected in reverse between two separate beams in a ceramic housing. It is generally used to protect two separate circuits or devices from malfunction or damage from transient surges, spikes or electrostatic discharge (ESD). The diodes are arranged with opposite polarities, so that when a voltage spike occurs, one diode conducts current while the other one remains reverse-biased, suppressing the surge.

The package of the SA20HE3/54 is hermetically sealed for surface mount devices, making it ideal for applications that require high reliability. It also has reverse stand-off voltage, which enables it to accurately identify what voltage value is to be regulated, even in severe environmental conditions. Moreover, the device has integrated protection against high frequency, electrostatic discharge (ESD), electrical fast transient (EFT), etc.

The SA20HE3/54 can support surge current up to 62A, pulse power up to 3000W, and peak pulse current up to 6A. In addition, it has a low capacitance value of 5pF, making it suitable for high speed data line protection applications. It also has very low clamping voltage, which avoids damage to the protected circuit during an over voltage condition.

In conclusion, SA20HE3/54 is a reliable transient voltage suppressor designed for communication applications. It is designed to suppress surge transients and ESD on high-speed data lines for overvoltage protection. This device has a low clamping voltage, high surge current capability, low capacitance, and reverse stand-off voltage, making it one of the most popularly used devices in the market.
