Transient Voltage Suppressor (TVS) diodes are a type of electrical circuit component that are used to protect electrical components, such as a computer, from voltage surges caused by electrostatic discharge (ESD) or electrical spikes from other sources. The TVS diode is designed to shunt any excessive voltages away from other components in the system providing a fast, and reliable voltage protection.

Within the category of TVS diodes, the TPD1E1B04DPYR is a 4-terminal, uni-directional, high voltage and high current protection device. It is designed to protect sensitive components in automotive, industrial, telecommunications, and consumer applications from over-voltage transients such as load dump, ESD, and lightning-induced surges.

The TPD1E1B04DPYR offers a wide range of features and benefits that make it valuable in many applications such as ECU automotive protection, industrial shunts, abrasion protection, protected end equipment, and for protection in systems subjected to high voltage and ESD strikes. In addition, it provides an ideal solution for high-speed signal applications, such as Ethernet/USB/HDMI cables, Ethernet switches, and high-speed data communication interfaces.

The TPD1E1B04DPYR consists of two distinct parts: the clamping circuitry and the protection circuitry. The clamping circuitry is a two-stage structure that offers high clamping voltage, fast response time and low capacitance. It also provides at least 25A peak pulse current capability and an 8kV ESD protection. The protection circuit consists of a P-N diode connected in reverse parallel to the two-stage ESD clamping circuit, providing protection against voltage transients.

When an over-voltage transient occurs, the TPD1E1B04DPYR clamps the voltage to a safe level by preventing further increase. This is accomplished by utilizing a combination of capacitors and the reverse-biased diode. Depending on the magnitude and speed of the voltage transient, the capacitors will discharge it along with the reverse-biased diode and the clamping circuit will then clamp the remaining voltage. The resultant clamping voltage will then be maintained until the transient has passed.

Overall, the TPD1E1B04DPYT is a versatile and reliable protection device that is used in many applications. Its superior features and benefits make it an ideal solution for a variety of applications including ECU automotive protection, abrasion protection, protected end equipment, and electrical systems subjected to high voltage and ESD strikes.
