SMA5J17AHE3/5A is a kind of TVS - Diodes. It is also known as Transient Voltage Suppression Diodes which are a type of device meant to protect other semiconductor components from damage due to high voltage stepping. They can be used to protect the circuits from damage due to overvoltage pulses, static electricity, lightning and other strong electric shock.

The SMA5J17AHE3/5A TVS-Diodes have an ultra-low capacitance of 0.3pF. They are unidirectional diodes with breakdown voltages ranging from 17V to 23V. The SMA5J17AHE3/5A also feature up to a 1500W peak pulse power dissipation rate. The Vces breakdown voltage range from 17V to 23V. The Clamping Voltage range from 25V to 35V. It has a low power consumption of 250mW and a fast response time in the range of 45ns.

The SMA5J17AHE3/5A offers multiple benefits in terms of their application. For instance, these diodes can be used in industrial, automotive, IT, communications and consumer electronics applications. They provide protection against automobile electrical system and electrical power equipment failures. They can be used for protecting the Telecom system with TVS protection.

The SMA5J17AHE3/5A has a working principle that involves protecting the circuit from overvoltage on the input line. If the voltage level on the input exceeds the rated breakdown voltage, the device will start to conduct current, thus allowing the output voltage to drop to the clamping voltage level. The device will then absorb the energy, dissipate it to the ground, and protect the circuit.

In order to ensure the SMA5J17AHE3/5A’s effective working, it is important to observe certain usage and placement guidelines. While placing the TVS-Diodes in the circuit, the input and output voltage should be observed respectively. The component should be placed in close proximity to the power supply unit to ensure that the voltage is regulated correctly. The placement of the TVS Diodes should be optimized to minimize power dissipation. They should also be place as close as possible to the supply and load terminals.

Overall, TVS-Diodes are an essential part of any circuit in order to protect delicate components from surge and overvoltage. The SMA5J17AHE3/5A offers superior performance in terms of power dissipation, capacitance, breakdown voltage, clamping voltage and response times. The device provides reliable overvoltage protection and serves as a reliable component used in automotive, telecom, IT, industrial and other fields.
