Diodes - Zener - Single

MZP4735ARL is a single 5.6V 500mW Zener diode from Diodes Incorporated. It is an economical SMD package that is used in applications where better stability and lower forward voltage drop is required.

Application Field

MZP4735ARL is used in many different applications, including:

• Power Supply Regulators – The MZP4735ARL is used to regulate the voltage of power supplies to ensure a consistent voltage under any load.
• MOSFET Gate Drive – The MZP4735ARL is used to drive high current MOSFETs with low voltage losses.
• Clamping Circuits – The MZP4735ARL is used to protect circuit components from high transient voltages and reverse current spikes.
• Signal Conditioning – The MZP4735ARL can be used to attenuate signals such as AC signals.

Working Principle

The MZP4735ARL is a regulated Zener diode, meaning it has a relatively fixed, or "regulated", reverse breakdown voltage. This is achieved by adjusting the doping of the semiconductor material of the diode to achieve a specific voltage. When a voltage less than the breakdown voltage is applied in reverse, the current is very low and the diode acts as an open circuit. When a voltage greater than the breakdown voltage is applied in either forward or reverse, the diode begins to conduct and can act as a rectifier.

When a voltage greater than or equal to the breakdown voltage is applied in reverse, the diode abruptly conducts current, limiting the voltage to the Zener voltage of the diode. This mechanism is what gives it its voltage regulation characteristic, allowing it to be used in applications such as power supply regulation and transient protection.

The MZP4735ARL also has a wide range of other characteristics that help to make it suitable for different applications. These include its low reverse leakage current and its low forward voltage drop.
