Specification

Description

The 1N4743A is a Zener diode known for its voltage regulation capabilities, designed to provide a stable reference voltage. It is particularly useful in various electronic circuits to protect sensitive components from overvoltage conditions.

Features:

Zener Voltage (Vz): The 1N4743A has a nominal Zener voltage of 13V, which is the voltage at which it stabilizes.

Power Dissipation: It can dissipate up to 1 watt of power, making it suitable for moderate power applications. Voltage Tolerance: It typically has a voltage tolerance of ±5%, ensuring reliable performance in voltage regulation.

Thermal Stability: The diode operates effectively over a wide temperature range, with a specified maximum junction temperature of 200°C.

Low Leakage Current: At voltages below the Zener breakdown voltage, it exhibits minimal leakage current, which is essential for maintaining circuit stability.

Applications:

Voltage Regulation: Used in power supplies to maintain a constant output voltage despite variations in the input voltage or load conditions.

Overvoltage Protection: Protects sensitive electronic components by clamping the voltage to a safe level.
