TVS (transient voltage suppressors), also known as transient voltage surge suppressors, are components used to protect circuits from potentially damaging overvoltage transients. The P4SMA100CA is a unidirectional unidirectional TVS belonging to the Lightly Loaded Series (LLS) family. It was designed to protect sensitive circuitry from electrostatic discharge (ESD) and other voltage transient events.

The P4SMA100CA device has a breakdown voltage- clamped voltage of ±100V and an available energy of 4.5kJ. It offers an excellent line of protection from short voltage spikes as a result of lightning strikes, static discharges, and high frequency interference. It is ideal for the protection of low voltage, AC line operated equipment such as TVs, computers, radios, washers, and dryers.

The P4SMA100CA is encapsulated in a low-profile, surface-mount DO-214AC package. The package includes two reverse diode stacks, a main diode, and an ESD diode. Its low capacitance minimizes signal degradation while its masking guard ring helps reduce the proliferation of ESD. It is RoHS-compliant and has a response time of less than 1ns and a -200V peak pulse current capability of 2A.

The P4SMA100CA is designed to suppress voltage transients caused by high energy events such as ESD, which can cause damage to connected components. Its internal Zener elements are also designed to limit the circuit between two levels, minimizing the impact on equipment operations.

The P4SMA100CA working principle is based on the principle of reversed biased suppression. When the transient voltage exceeds the device\'s breakdown voltage, the excess energy is dissipated in the device\'s two internal Zeners. When the voltage returns to normal, the active device returns to its typical, low leakage state. In this mode, the P4SMA100CA is able to provide a high degree of protection from transient voltage events.

The P4SMA100CA is a reliable and cost-effective protection solution for low voltage systems and is an excellent option for a wide range of applications requiring overvoltage protection. Its small form factor makes it ideal for use in consumer electronics, automotive, industrial, and networking systems. Its robust construction and fast switching speed enable it to reliably protect equipment against ESD and other voltage transients. This robust performance makes it a suitable component for use in a wide range of applications.
