A Zener diode is a type of diode with a greatly increased reverse breakdown voltage so that it’s breakdown results in an avalanche across the entire depletion region rather than a single p-n junction. 1PMT5915B/TR13 is one such diode. It is a single Zener diode. This article will look into its application field and working principle.

Applications
The 1PMT5915B/TR13 Zener diode is widely used in a range of industry applications. It is most commonly used in power supply circuits. Its breakdown voltage is suitable for applications that require operating voltage regulation, so it is highly suitable for applications such as voltage reference, voltage stabilizer circuits, voltage limiting, voltage rectifying, overvoltage protection circuits etc. Its maximum breakdown voltage is 15V which makes it ideal for low-voltage AC-DC conversion especially in power supplies for embedded systems, computers, and other electronic devices.

Working Principle
A Zener diode is essentially a special type of diode with a very large-area p-n junction that is designed to breakdown at a certain voltage. It consists of a heavily doped p-type semiconductor material and a lightly doped n-type semiconductor material. When a reverse bias is applied to the diode, the built-in electric field overcomes the depletion region’s potential and causes a large number of electrons to migrate from the n-type to the p-type semiconductor material. This process is known as the Zener effect and it results in the diode breaking down at a certain voltage, known as the breakdown voltage, after which it conducts heavily. This breakdown voltage is slightly affected by the temperature, so a Zener diode can provide voltage stabilization over a wide temperature range.

The 1PMT5915B/TR13 Zener diode is a single Zener diode and its maximum breakdown voltage is 15V. It operates in reverse bias and has built-inclamps which provide protection from excess voltage. The breakdown voltage is temperature-stable so that it can provide consistent voltage regulation over a wide temperature range. Its maximum surge current is 250mA and the maximum forward current is 8mA.
