TVS (transient voltage suppressor) diodes are designed to protect electronic and sensitive systems from Transient Voltage Spikes (TVS). The type P4SMA82A is a surface mount TVS diode especially designed for the protection of telephone lines. It enables the protection of sensitive ICs/MCU/DSP circuits from high voltage transients induced by lightning and other forms of electrical noise.

The P4SMA82A is capable of peak pulse power dissipation of 1.2 kW and a maximum peak pulse current of 8.2 A. It has an operating temperature ranging from -55ºC to 125ºC. With a breakdown voltage of 82V, it is a really robust TVS diode offering an impressive level of protection. Its lightning surge robustness is IEC 62757-2 Level 3 and its ESD robustness is IEC61000-4-2 Level 4, class C. The soldering temperature of the P4SMA82A should be a maximum of 260°C.

The main application field of P4SMA82A is the protection of Telephone Equipment. But it can be used in other applications where similar protection is needed. It is popularly used for protection from Electrostatic Discharge, Lightning, Electro-Magnetic Interference, Electrical Over-Stress, as well as for other voltage transients. It can be used on automotive and communications applications as well.

The functionality of the P4SMA82A diodes is relatively uncomplicated. In simple terms, during normal operation, the diodes remain non-conducting, allowing current to flow normally through the circuits as designed. If, however, a higher-than-normal voltage is introduced, the diode will conduct this excessive current away from the circuit. When the voltage returns to normal, the diode will stop conducting and the circuit will continue to operate as it was designed.

The P4SMA82A TVS diodes offer a reliable level of protection for circuits against transient spikes. It has a fast response time and low clamping voltage, thus providing excellent ESD and surge protection while maintaining signal integrity. Its design, small form factor and wide operating temperature make it a popular choice for many applications.
