TVS - Diodes

Transient Voltage Protection (TVS) diodes are a type of semiconductor device used to protect sensitive electronic circuits from over voltage surges and electrical transients. A TVS diode is a voltage-dependent nonlinear device which is designed to protect against electrical transients such as ESD, lightning, electrical noise, and other voltage spikes. As a class of voltage dependent diodes, TVS diodes can be used in different applications such as surge suppression, over-voltage suppression, power line protection, noise protection, and other applications where overvoltage protection is needed.

SMA6T33AY is a TVS diode specifically designed for protection against high-surge transients. This diode is specifically designed for applications requiring high surge protection such as those found in power line protection and over-voltage protection. This TVS diode features an ultra-high surge current capability with a high-clamping voltage of 6.3V and a low operating voltage of 5.0V, making it suitable for a wide range of applications.

The SMA6T33AY is designed with a ultra-high surge current of 40A and a maximum stand-off voltage of 25V. This diode has a low-capacitance of 2pF, and an operating temperature range of -40° to +85°C. The device has a small surface mounted profile, making it suitable for applications where space is limited. This diode meets UL ratings of 1449, 4th edition, and has a peak pulse power rating of 108W.

This TVS diode works by clamping the voltage above a specified level, thus preventing the voltage from damaging sensitive electronic components. The diode consists of two terminals; one is the cathode and one is the anode. The anode of the diode is connected to the source of the transient, while the cathode is connected to ground. When a transient or over-voltage surge is applied to the input, the diode begins to conduct and provide protection against the transient. The diode will not conduct unless the voltage exceeds its breakdown level. When a surge or transient occurs, the diode will become forward biased and conduct current, thus protecting the circuit.

The SMA6T33AY is an ideal diode for applications requiring over-voltage protection in high surge currents. It offers an instantaneous response to transients and has an operational temperature range of -40° to +85°C. This diode is an ideal choice for protecting sensitive electronics from damage due to transients and high-surge currents.
