TVS diodes are essential components in modern circuit design. A TVS diode, also known as a transient voltage suppressor, is an active device used to suppress transient overvoltage and redirect electricity. The 5KP100-E3/73 is one of a series of bidirectional unidirectional TVS diodes manufactured by Diodes Incorporated. This series offers excellent electrical characteristics, providing high transient voltage protection performance in various topographies.

The key feature of the 5KP100-E3/73 is its bidirectional unidirectional technology. Bidirectional TVS diodes block large-amplitude differential voltage surges and protect circuits by maintaining circuit integrity in both the positive and negative polarity directions. The unidirectional technology also allows the diode to withstand low-amplitude noise transients in either direction. It is a prime choice for protection in low capacitance applications.

The 5KP100-E3/73 is designed for applications where very low let-through voltages are required. It has a peak pulse power rating of 600W and an energy rating of 200J. It is available in an 8-lead, surface-mount SOD-723 package, which allows for superior thermal performance and easier board mounting, ultimately allowing the device to provide protection from large-amplitude surge pulses. The 5KP100-E3/73 is suitable for low-capacitance ESD protection applications.

In terms of its working principle, the 5KP100-E3/73 operates in two stages: the breakover circuit and the Clamping Circuit. The breakover circuit of the device acts as a voltage trigger, sensing large voltage transients, such as ESD events, load dumping, or circuit mis-operation. When the voltage reaches a certain threshold, the breakover circuit triggers onto the Clamping Circuit, which redirects the energy from the transient back into the supply rails. This minimizes the overvoltage induced by the transient and reduces the amount of let-through energy in the system.

The 5KP100-E3/73 is an ideal transient voltage suppressor for use in products such as charging adapters, LED lighting systems, industrial power supplies, automotive electronics, medical equipment, and more. With its bidirectional unidirectional capability, low let-through voltages, and high thermal performance, the 5KP100-E3/73 provides superior protection for sensitive circuit components.
