1PMT5951C/TR7

Diodes - Zener - Single

The 1PMT5951C/TR7 is a single diode from the diode family called Zener. This diode is a three terminal device where its anode, cathode and gate are represented by the letters A, K and G respectively. An important property of this diode is its reverse break-down which results in current flowing under reverse bias.

What is 1PMT5951C/TR7?

1PMT5951C/TR7 is a type of semiconductor diode, also known as a Zener diode. This diode consists of two regions or diodes, the p region and the n region, both of which are connected with each other by a region of very high impedance. This is known as the Zener breakdown voltage, hence it is referred to as a Zener diode. After this breakdown voltage is reached, current begins to flow and the diode enters its breakdown mode.

Application Field of 1PMT5951C/TR7

The 1PMT5951C/TR7 is mainly used in circuits, where a constant current source needs to be created. It is a suitable for dealing with a wide range of devices and applications. It is used in voltage regulators, voltage clippers and voltage multipliers, audio amplifiers, and inductive loading applications like those seen in relay coils, motors, and transformers. It can also be used to act as protection against inductive arcing.

Working Principle of 1PMT5951C/TR7

The 1PMT5951C/TR7 works in the same way as other Zener diodes. As the voltage across this diode exceeds its breakdown voltage, a current controlling effect kicks in and gradually increases with voltage, making the diode act as a constant current source. The Zener diodes are allowed to operate in reverse bias and therefore act as voltage protection devices. This is due to the properties of the Zener breakdown, which results in current flow and regulates the excessive voltage.

Advantages of 1PMT5951C/TR7

1PMT5951C/TR7 is a beneficial element as it has a wide range of applications. It acts as an efficient current regulator and a reliable voltage protection device. Zener diodes are mostly unidirectional and therefore easier to integrate with the rest of the circuits. They are highly reliable and cost effective, making them ideal for bulk applications, especially in low to medium power applications.

Conclusion

To sum up, the 1PMT5951C/TR7 is a highly efficient diode that can play multiple roles in a wide range of circuits and applications. It acts as a constant current source or voltage protection device, depending upon the setup. It is cost effective, unidirectional, and highly reliable element that is mostly used in small and medium power applications.
