1N4764A-T

The 1N4764A-T is a single Zener diode. It is a diode specially designed to allow reverse current to flow, when a voltage higher than the Zener voltage is applied to the diode. This kind of diode is designed to regulate the voltage across the diode at the Zener voltage. It is an efficient device to protect electronic systems from transient voltage peaks due to switching.

The 1N4764A-T has a wide range of applications. It can be used in a variety of circuit designs to provide protection against voltage spikes. These voltage spikes can be caused by lightning strikes, accidental short circuits, or by the over-voltage surge that occurs when an electronic system is shut down. The 1N4764A-T can protect logic circuits from those voltage spikes. It can also be used in power supplies, motor controls, relief relays, and other situations where it is necessary to protect a circuit from excessive voltages.

The working principle of the 1N4764A-T is simple. It consists of two electrodes; a cathode and an anode, and a thin sliver of Zener material between them. When the reverse voltage is higher than the Zener voltage, the Zener material breaks down, which allows reverse current to flow through the diode. This current is limited by the working resistance of the diode. The diode will remain in the breakdown state as long as the reverse voltage is higher than the Zener voltage.

This Zener diode also has a wide operating temperature range, from -55°C to +125°C. This makes it ideal for use in high-temperature environments. The 1N4764A-T has a reverse voltage of 5.1V and a power dissipation of 500mW. It also has a maximum peak reverse voltage of 7.2V and a peak forward surge current of 1A.

The 1N4764A-T is a versatile diode with many applications. It is reliable, efficient, and capable of providing excellent protection against sudden voltage spikes. Its wide temperature range makes it ideal for use in extreme conditions. The 1N4764A-T is a reliable and cost-effective choice for protecting electronic systems from voltage surges.
