Introduction:

1PMT4114C/TR13 is an ultra low power Zener diode that is commonly used in many common electronic applications. This diode will protect an oscillator or pulse generator from damage by providing a controlled current to the junction with the resistor. It is available in an SC-70 package and has an internal temperature coefficient of -3.3mV/OC. The 1PMT4114C/TR13 is a widely used diode for protecting high-precision devices from over-voltage conditions, and is suitable for general applications.

Applications:

1PMT4114C/TR13 is mainly used in applications where voltage protection is desired. It is commonly used in automotive electronics, computers, and telecommunications equipment, where it can be used to prevent damage to the components, usually due to a power surge. The 1PMT4114C/TR13 can also be used in power supplies, where it can provide a controlled current to help stabilize the output voltage and current. Additionally, it can also be used in high-precision applications, such as scientific instruments, where its low power consumption helps ensure accuracy and reliability.

Working Principle:

The 1PMT4114C/TR13 operates on the principle of Zener breakdown. Zener breakdown is the phenomenon in which a reverse bias diode experiences a sharp increase in current flow when the applied voltage reaches a certain level. This level is called the Zener voltage, which for the 1PMT4114C/TR13 is 4.1V. When the reverse bias voltage reaches the Zener voltage, the electron-hole pairs that have been created in the junction will rapidly move to the opposite sides and a large current will flow from the anode to the cathode. This current will then be limited by the power resistor connected to the diode, as it is designed to reduce the current to a safe level.

Conclusion:

The 1PMT4114C/TR13 is a popular diode for voltage protection applications, as it can provide protection while consuming low power. It is suitable for a wide range of uses, including automotive electronics, scientific instruments, and power supplies. Furthermore, it operates on the principle of Zener breakdown, where a sharp increase in current flow occurs when the applied voltage reaches the diode\'s Zener voltage.
