Specification

Description

The 1N4746A is an 18V Zener diode, widely used in electronic circuits for voltage regulation and as a voltage reference. Zener diodes are designed to operate in the reverse breakdown region, providing a stable reference voltage. The 1N4746A is part of the well-known 1N47xx series, recognized for its reliability and precision.

Features :

Voltage Rating: The 1N4746A has a Zener voltage of 18V, ensuring a stable 18V across its terminals once the reverse breakdown voltage is reached.

Power Dissipation: This diode can dissipate up to 1 Watt of power, suitable for various medium power applications.

Tolerance: The Zener voltage tolerance is typically ±5%, which ensures precise voltage regulation.

Package: It comes in a DO-41 (axial leaded) package, facilitating easy mounting on printed circuit boards (PCBs).

Temperature Stability: The 1N4746A offers excellent stability over a wide temperature range, maintaining consistent performance under varying environmental conditions.

Low Leakage Current: It features a low leakage current in the reverse bias condition, minimizing power losses.

Applications:

Voltage Regulation: The primary use of the 1N4746A is to provide a stable reference voltage in power supplies, ensuring consistent output voltage despite variations in input voltage or load conditions.

Protection Circuits: It is employed in over-voltage protection circuits to safeguard sensitive electronic components by clamping the voltage to a safe level.
