TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are a form of unidirectional protection that defends against transient voltage events. The SA30CA-T is an example of a TVS diode with a unique combination of features to protect circuit boards, components, and systems from overvoltage transients. A TVS diode can be used in critical applications such as appliances, automotive electronics, consumer electronics, data processing systems, industrial and telecom systems, instrumentation, and servers.

Application Field

The SA30CA-T is designed to protect against overvoltage and overcurrent transients in equipment exposed to harsh electrical environments. It can also provide surge protection with low clamping voltage from 1W to 3.5W. With an operating current range from 2 to 3 amps, the device can be used in a wide range of applications. It is ideal for protecting against lightning, electrostatic discharge (ESD), and otherelectrical transients and is compatible with soldering temperatures up to 260° Celsius.

Working Principle

The SA30CA-T is an avalanche diode designed with an integrated elements consisting of a small signal diode, a resistor, and a zener diode. When the device is exposed to a transient voltage, the voltage across the diode increases and the diode becomesconductive. This conducts the excess current through the series resistor, thus limiting the current across the diode. The current is then transferred to the zener diode, which then clamps the voltage across the device. When the voltage is removed, the device quickly returns to its normal state.

The SA30CA-T is designed to provide efficient protection against high-energy, high-current transients. It is designed to reduce the voltage clamping level required to protect against ESD and lightning surges, which helps to reduce power dissipation. Its ability to provide increased surge capability and flexibility in package configuration make it a great choice for easily protecting against surges and transients.
