TVS - Diodes

A TVS diode is a transient voltage suppressor, which is a form of semiconductor device that is designed to protect circuits from high voltage transients. Its purpose is to absorb and clamps high voltage transients that could damage other components of a system.

The D1213A-01WS-7 is a unidirectional TVS diode specifically designed for electrostatic discharge (ESD) protection. It is designed to protect sensitive electronics such as microprocessors and integrated circuits from static electricity, electrostatic discharge, and high-energy electrical transients.

Application Field

The D1213A-01WS-7 is suitable for applications that require reliable ESD protection. It can be used in many environments including automotive, telecommunications, medical, industrial, and consumer electronics, among others. It is also compatible with most standard ESD test methods.

It has a low capacitance, which is ideal for data and signal line protection. The diode also has a low leakage current, making it ideal for circuits working at low voltage, such as microprocessors and other low power devices.

Working Principle

The D1213A-01WS-7 diode is designed to protect sensitive circuits from ESD and other electrical surges. It is composed of two distinct chips, and each performs a specific role. The first chip is a Zener diode, which clamps the voltage to a predetermined level. The second chip is an avalanche diode, which breaks down the voltage to a much lower level.

When an ESD or other transient surge occurs, the Zener diode clamps the voltage to a predetermined level, allowing the avalanche diode to break down the remainder of the voltage. This prevents further damage to sensitive circuit components. As the surge passes, the voltage is clamped to a level that is safe for the device.

The D1213A-01WS-7 is designed to withstand up to 8 kV, with a low leakage current and a low capacitance of 0.03 pF. It is able to provide reliable ESD protection, and is compatible with most ESD test methods.

In summary, the D1213A-01WS-7 is a unidirectional TVS diode designed for ESD protection. It is designed to protect sensitive components from ESD and other transient surges, and has a low leakage current and capacitance. It is suitable for applications requiring reliable ESD protection, and is compatible with most ESD test methods.
