MMBZ4627-E3-18

The MMBZ4627-E3-18 is a single zener diode primarily used as voltage regulator and provides a stabilized, regulated output. The single zener diode helps in controlling the maximum voltage level available to a circuit. The device relies on a reverse breakdown phenomenon, where the current starting to flow in the reverse direction when the voltage is increased past a certain limit, known as crest breakdown voltage.

The MMBZ4627-E3-18 is designed for use in applications requiring a regulated voltage source of 18V or less. This diode has a low profile form factor, making it suitable for tight space applications. It is also rated for an operating temperature range of -55°C to +150°C, making it suitable for use in hostile environments.

When connected with a circuit, the device will be in a reverse bias. As the circuit is powered up, the electric current flowing through the diode will remain low until the diode reaches its zener voltage. At this point, a proportionally large increase of electric current will be noticed. The current will remain constant up to some point, after which it will drop to zero. Beyond this point, the device will not be able to perform its role as a voltage regulator and will allow more current to flow through the circuit than it can handle.

The device is made with a proprietary process and has a robust construction. The zener diode has a low leakage current, which helps keep the stable voltage output in control. Due to the low profile form factor, the device occupies lesser space on the printed circuit board (PCB). Also, the diode has a high reverse breakdown voltage of up to 22.5V.

The MMBZ4627-E3-18 is an enhancable, surface mount, single zener diode that is commonly used in voltage regulator circuits. It features low leakage current, a low profile form factor, and a high reverse breakdown voltage. The device is suited for use in applications with tight space requirements, hostile environments, and requires a regulated voltage source of 18V or less.
