The 1PMT4101/TR7 is a single zener diode. It is designed to provide low voltage regulation and can protect sensitive components from high voltage transient events. It features a low forward voltage drop and a fast reverse recovery time. The 1PMT4101/TR7 can be used in a variety of applications such as power suppression, over-voltage protection and circuit protection.The 1PMT4101/TR7 is a Silicon Epitaxial Zener Diode. When used in zener breakdown mode, its peak inverse voltage rating is -6V to -81V with a reverse current range from 1mA to 95mA. Its power dissipation is 300mW up to a maximum of 400mW. It has a maximum forward current of 2A and a maximum forward voltage drop of 1.1V. It has a capacitance range of 1.4 pF to 8.2 pF. It has a thermal resistance of 0.072 °C/W and a maximum junction temperature of 125 °C.The characteristics of the 1PMT4101/TR7 make it suitable for many applications in both AC and DC circuits. It is particularly suited for applications where an unidirectional voltage trigger is required, such as in overvoltage protection circuits. The device can provide protection against electrical transients, including those generated in switch-mode power supplies, power factor correction circuits and motor drives.The working principle of the 1PMT4101/TR7 is quite simple. When the voltage across the device rises above its zener voltage, it starts to conduct and prevents the voltage from rising further. This can protect sensitive components from high voltage transients. Likewise, when the voltage across the device falls below its zener voltage, it stops conducting and the voltage can fall no further. This can prevent damage caused by low voltage events.In conclusion, the 1PMT4101/TR7 is a single zener diode, designed for use in applications such as power suppression and over-voltage protection. It has a low forward voltage drop, fast reverse recovery time and low power dissipation, making it suitable for many AC and DC applications. The working principle of the device is quite simple and it can provide reliable protection against electrical transients.
