1N4762CE3/TR13

1N4762CE3/TR13 is a diode classified as a single Zener type. It is designed to be used in a wide range of applications, such as reverse voltage protection against ESD, as a reference source, or in power supplies.

Application field

1N4762CE3/TR13 is a 5.1V Zener diode, with a Zener voltage tolerance of 5% and a nominal power dissipation of 500 mW. It is suitable for use in applications requiring relatively low voltage levels. It is also suitable for use in a wide range of applications, including reverse-voltage protection against ESD, reference sources, and power supplies. Additionally, it can be used as a shunt regulator, as a voltage regulator in switching-mode power supplies, or as a voltage clipper.

Working Principle

1N4762CE3/TR13 operates on the principle of Zener breakdown, where the reverse breakdown occurs when the reverse bias voltage exceeds the Zener breakdown voltage. When the device is reverse-biased, the P-N junction carries a voltage known as the Zener voltage, which is primarily determined by the P-N junction characteristics. The device then begins to conduct when the voltage reaches the Zener Breakdown Voltage (VZ as marked on the product), and the steady-state current passes through the diode.

As more current is passed, the voltage drop across the diode continues to increase until the diode reaches a certain current density, where the diode quickly saturates and a large amount of current will pass through. The Zener breakdown voltage for 1N4762CE3/TR13 is 5.1V. Additionally, the breakdown voltage is maintained during temperature variations, ensuring high accuracy for the stated applications.
