Working Principle

The working principle of PDTA123TU, 115 is based on the PN Junction. It consists of two semiconductor layers - an n-type layer and a p-type layer - doped with impurities to form a distinct n-type and p-type region respectively. Current flows through the device when a voltage is applied to the device, allowing a current to flow through the channel region.The device also acts as a current limiter, allowing the current to flow through the channel only if it meets the device’s threshold current limit. This prevents too much current from flowing through the load.

The device also acts as a protection device, protecting the load from over-voltage, over-current and other forms of electrical overload. The device protects the load by limiting the flow of current through the channel and by absorbing the extra voltage or current. This reduces the risk of damage to the load and helps maintain the safety of the surrounding components.

The device also consists of a Zener diode, which is used to monitor the voltage across the device. It allows small amounts of current to flow when the voltage exceeds the set value, protecting the device from excessive voltage fluctuations. This helps maintain safe operation of the device, even under extreme conditions. In addition, the device can also be used to provide electrical isolation between the load and the power source.

PDTA123TU, 115 is a reliable, cost effective solution for managing power in a variety of applications. It offers superior thermal characteristics, low voltage drop, and current limiting and protection capabilities, making it an ideal choice for demanding and space-constrained applications.
