1N6297A-E3/73 Circuit Protection

The 1N6297A-E3/73 is a unidirectional “Zener” diode that is used predominantly in TVS (Transient Voltage Suppression) applications. It is particularly well-suited to provide transient over-voltage protection for sensitive electronic components.

A Zener diode is a special type of diode used in voltage regulators or in reverse polarity protection circuits. The 1N6297A-E3/73 combines the typical properties of a Zener diode with an additional protection against transients. It can shunt a surge of up to 73 volts and its clamped voltage is responsible for limiting the electric current during these surge events. This over-voltage protection feature makes it suitable for use in a variety of TVS applications where transient over voltages might otherwise damage or disrupt electronic systems, such as in automotive, industrial, and medical settings.

The 1N6297A-E3/73 is made of a semiconductor substrate material and is packaged as a standard SOD-123 (small outline diode) component. It has a maximum forward-voltage drop of 1.2 volts and a maximum reverse-currents rating of 5 mA. It has a maximum power dissipation rating of 1 W and is able to dissipate up to 900 mW of energy. It has a reverse breakdown voltage of 47 volts and a maximum forward voltage of 1.2 volts. It is also able to remain stable over a wide temperature range (−65 to + 175 °C).

The Zener diode is able to respond quickly in the event of a transient over-voltage due to its low inertia and fast response time. This is because the diode is able to switch its state from forward current to reverse current in a few nanoseconds in the event of an over-voltage surge. The 1N6297A-E3/73 is specially designed for these types of applications and is able to effectively absorb the over voltage and current resulting from the surge event without causing damage to the system.

The 1N6297A-E3/73 thus provides excellent over-voltage protection for sensitive electronic components such as microprocessors, memory devices, and other types of integrated circuits. It can be used in a variety of applications including automotive, industrial, and medical systems. Its compact packaging and fast response time make it a suitable choice for TVS applications.
