MMSZ5238C-E3-08 is one of the many types of single zener diodes that are used as components in electronic circuits. It is an avalanche-breakdown diode. Zener diodes are frequently used to provide a voltage reference, voltage regulation, or as a switching device. The MMSZ5238C-E3-08 is manufactured by Diodes Inc. and is offered in a SOD-323 package.

A zener diode is a type of diode that allows conventional current (DC) to flow in one direction only, in the forward direction. When the diode is reverse-biased, it will not conduct. However, if a sufficiently large voltage is applied in the reverse direction, the electrons in the junction will have enough kinetic energy to create electron-hole pairs and start the flow of the current in the reverse direction. This is known as the Zener breakdown effect.

The Zener breakdown effect is used to control the voltage in some electronic circuits. The reverse-biased diode can be combined with a resistor in series, such that the resistor limits the current flow through the diode and the voltage across the diode will be constant, no matter how much the current increases. This set up is known as a zener diode voltage regulator.

The MMSZ5238C-E3-08 is a single zener diode with a nominal breakdown voltage of 8.2V and a maximum power dissipation of 200mW. It has a maximum reverse voltage of 6V and a maximum forward current of 200mA. It has a Zener voltage tolerance of ±5% and a maximum Zener impedance of 1.4Ω. These specifications make the MMSZ5238C-E3-08 ideal for applications such as voltage regulation in negative polarity output and reverse battery protection, supervisory circuits, audio gain and level control, and noise suppression.

The MMSZ5238C-E3-08 is housed in a SOD-323 package, which is a low-profile, Surface-Mount Device (SMD) package designed to offer higher density packaging and improved mounting flexibility in a wide variety of circuit applications. Other features of the MMSZ5238C-E3-08 include low-cost packaging, improved thermal properties, and superior electrical performance.

In summary, the MMSZ5238C-E3-08 is a single zener diode with a breakdown voltage of 8.2V and a temperature range of -55°C to +125°C. It is offered in a SOD-323 package and is ideal for applications such as voltage regulation, reverse battery protection, supervisory circuits, audio gain and level control, and noise suppression.
