SMCJ1.5KE27A-TP Circuit Protection

TVS - Diodes are specialized, high-voltage diodes designed for the protection of sensitive electronic components and systems.

The SMCJ1.5KE27A-TP is one such, high performance unidirectional and bidirectional transil device used mainly in an array of telecommunications networks and communication equipment. This device is designed to withstand a high surge current to provide superior over-voltage protection for sensitive components from exposure to over-voltage transients that may originate from a variety of sources such as lightning, electrostatic discharge, automotive load dump and inductive transients.

Application Field:

The SMCJ1.5KE27A-TP devices are ideally suited for a wide range of applications, where they provide circuit protection for safety isolation components, power supplies, and telecommunications equipment, computer systems, automotive electronics and industrial control systems. These end-use applications are commonly found in the automotive, medical, military, consumer and telecommunications field.

Working Principle:

In operation, the SMCJ1.5KE27A-TP device is designed to bridge a threshold voltage between the input and output terminals, and trigger a voltage clamping action when the trigger voltage exceeds the level set by the design. When a surge of excessive voltage is applied to the device, the typically low internal capacitance allows the device to act like an open switch, protecting the circuit from the surge. The device then acts as a low impedance path, diverting excessive energy to ground.

In addition, these devices are rated to protect existing equipment from a variety of transient voltage events, including exceeding the rated peak pulse voltage, exceeding the rated breakdown voltage and over-loading current ratings. The device also features a low clamping voltage and low clamping energy. This reduces the amount of additional heat generated due to the transient surge and allows the system to be operational as soon as the transient has been shorted.

Therefore, the SMCJ1.5KE27A-TP can provide superior protection from over-voltage transient events and help to protect both sensitive electronic components and systems from possible damage.
