TVS - Diodes represent a class of electronics components specifically designed to provide a reliable level of protection from electrostatic discharge (ESD) and other transients. The SA100A-E3/54 is a unidirectional bi-directional diode in a SMT package, rated for 5.4 Volt ESD and 10 Kiloamp surge. It is designed for a broad range of application fields that require strong protection against damaging transients.

Application Fields

The SA100A-E3/54 is capable of withstanding ESD levels up to 10 KV in accordance with the IEC 61000-4-2 standard. As a result, it is ideal for applications such as mobile equipment, IT systems, industrial automation, medical device equipment, automotive power systems, and military electronics. Wherever protection from ESD and other transients is essential, the SA100A-E3/54 can provide an ideal level of protection.

Working Principle

The SA100A-E3/54 utilizes a diode-based design to protect against transients and ESD. It is built using two back-to-back Zener diodes with a small-series resistance. This combination allows the device to react quickly to incoming surges and helps control its maximum voltage rating. The device is designed to diode-clamp in order to suppress transients and reduce the peak voltage to a predetermined level.

As the current passes through the Zener diodes, the resistive element reduces the total clamping voltage. This helps to reduce the peak voltage to a more manageable level. The combination of these elements allows the device to react quickly to surges and spikes and protect the device it is protecting.

In addition to providing protection from transients and ESD, the device also features a low stand-by current and short recovery times. This helps to reduce the effects of false triggering and enables the device to recover quickly from a surge. This helps to protect against any subsequent surges that may occur due to the over-voltage condition.

Summary

The SA100A-E3/54 is a bi-directional diode designed to provide reliable protection against electrostatic discharge (ESD) and other transients. It is rated for up to 5.4 Volt ESD and 10 Kiloamp surge, making it suitable for a wide range of applications. The device utilizes a diode-based design to clamp down on transient voltage and reduce the peak voltage to a predetermined level. It also features a low stand-by current and short recovery times, making it capable of quickly and reliably protecting the device it is protecting.
