MMBZ4623-E3-18

Diodes - Zener - Single

The MMBZ4623-E3-18 is a single Zener diode which is widely used in applications as a low power, low voltage clamping device. It consists of a semiconductor diode connected in a reverse voltage polarity. This makes the MMBZ4623-E3-18 to have exceptional impulse power and energy outcomes compared to its predecessor models. The maximum reverse voltage rating of MMBZ4623-E3-18 is 18 V and the power rating varies from 0.5 W to 1 W.

Working Principle of the MMBZ4623-E3-18

MMBZ4623-E3-18 operates in accordance with a reverse voltage polarity where current flows from the cathode to the anode. When the forward current reaches the Zener breakdown voltage, it remains less than the actual value. The voltage at which this breakdown occurs is known as the Zener voltage. This breakdown voltage is marked on the label of the package. When the applied voltage exceeds the Zener voltage, the Zener diode turns and passes the reverse current.

Applications of the MMBZ4623-E3-18

The MMBZ4623-E3-18 is used in a variety of applications due to its outstanding features. It is mainly used in voltage regulation, voltage clamping, voltage reference, and in surge and switching protection. Furthermore, the Zener diode is also used in combination with BJTs and FETs for voltage regulator and shunt regulator applications. Due to its excellent performance, many automotive and microcontroller applications use the MMBZ4623-E3-18 diode.
