TVS - Diodes: PTVS10-170C Application Field and Working Principle

TVS (Transient Voltage Suppression) diodes are widely used components that provide ESD (electrostatic discharge) protection, surge protection, and transients suppression. The PTVS10-170C is one of the most commonly used TVS diodes, and is often used in the telecommunications industry for telecommunications lines, power supply, terminal protection, and decoder protection. Its features include high ESD protection level, wide operating temperature range, low leakage current, and low clamping voltage.

The primary application of the PTVS10-170C is ESD protection. Its clamping mechanism works by clamping the voltage increase of a transient event to an allowable voltage level. It works by providing a path for the current generated by the transient to flow through, and thus dissipates the energy and prevents the surge from damaging the sensitive devices connected in the circuit. The PTVS10-170C is ideal for use in sensitive electronic systems, and can protect against transients with up to 8kV ESD, which is beyond the standard requirements of most ESD protection systems. This makes it suitable for use in the most demanding applications.

The way in which the PTVS10-170C works in providing ESD protection is based on the principle of a voltage limiter. It consists of a diode string composed of two or more widely spaced reverse-biased zener diodes connected in parallel, forming a 3 junction barrier. When a transient event occurs, it causes a voltage increase in the circuit. This voltage increase is detected by the TVS diode, which then activates the diode’s clamping mechanism. The voltage increase is limited to the specified diode break-down voltage by shunt regulation, preventing any further current from flowing through the circuit and damaging sensitive components. The diode will then be reset after the transient has passed, and it will be ready to provide protection against a new transient event.

The PTVS10-170C is a good choice for use in applications that require the highest level of ESD protection. It is also a good choice for applications that require fast response times, as it is designed to ensure a fast response time to transients. Additionally, the PTVS10-170C is designed to have a very low clamping voltage, which makes it suitable for use in low voltage applications. As with all TVS diodes, the PTVS10-170C provides excellent protection from ESD and other transient events.
