Diodes - Zener - Single

The 2EZ150D/TR12 is a single zener diode commonly used for voltage regulation. It\'s small size makes it ideal for applications where space is at a premium. This diode has a breakdown voltage of 15V, making it suitable for most low voltage regulation needs.

Application Field

The 2EZ150D/TR12 is mostly used in low voltage electronic devices, such as microprocessors, RAM, and storage units. It is also commonly used in automotive applications, such as immobilisers, where a stable voltage is required for reliable operation. The positive temperature coefficient of this diode ensures its performance remains consistent even when faced with extreme temperatures.

Working Principle

The 2EZ150D/TR12 is a Zener diode, which means it is specifically designed to regulate voltages. It consists of a semiconductor material that has both N and P type regions, forming a structure known as a PN junction. When reverse biasing is applied to the diode, the electric field generated is strong enough to "break down" the PN junction, allowing current to flow.

When a voltage greater than the Zener voltage is applied to the diode, it starts to conduct, limiting the current to a level that is determined by the Zener voltage. This creates a stable voltage across the diode, allowing for reliable regulation.
