Specification

Description

The 1N4728A is a Zener diode designed for voltage regulation applications. Zener diodes are a special type of diode that allows current to flow not only from anode to cathode, like a regular diode but also in the reverse direction when the voltage is above a certain value known as the Zener breakdown voltage. The 1N4728A has a breakdown voltage of 3.3V and can dissipate up to 1 watts of power. This makes it suitable for use in various electronic circuits where precise voltage regulation is required.

Key Features:

Zener Voltage: 3.3V The diode stabilizes the voltage at 3.3V, making it ideal for low-voltage regulation applications.

Power Dissipation: 1 Watt Capable of dissipating 1 watts of power, suitable for moderate power regulation tasks.

Tolerance: ±5% The Zener voltage has a tolerance of ±5%, ensuring reliable performance within this range.

Operating Temperature Range: -65°C to +200°C The wide temperature range allows the diode to operate in various environmental conditions.

DO-41 Package The diode comes in a DO-41 plastic package, which is a standard axial leaded package for through-hole mounting.

Low Leakage Current The 1N4728A has a low leakage current, ensuring minimal current loss when reverse-biased below the Zener voltage.

Applications:

Voltage Regulation Used in power supplies to maintain a constant output voltage of 3.3V, protecting sensitive electronic components from voltage fluctuations.

Reference Voltage Acts as a stable reference voltage source in precision circuitry, such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).
