1PMT5920/TR7

The 1PMT5920/TR7 is part of a wide family of diodes offered by NXP Semiconductors. It is a single Zener diode, meaning it is composed of a single p–n junction between two semiconductor layers. 1PMT5920/TR7 is a low-power diode, operating with a maximum average forward current of 297 mA and can handle a maximum reverse voltage (peak) of 65 V. As with all semiconductor components, the 1PMT5920/TR7 can be used to send signals, direct current, and generate power.

The most common application area of the 1PMT5920/TR7 is as a flyback diode, also known as a freewheeling diode, across an inductive load that is driven by a voltage source. When the voltage source is removed, the 1PMT5920/TR7 allows the current in the inductive load to discharge, which avoids the generation of high voltages due to the switch\'s inductance. With the help of the 1PMT5920/TR7, the reverse voltage generated while the inductive load is switched off is limited. The 1PMT5920/TR7 can also find its use in voltage regulators, providing steady production of power.

The 1PMT5920/TR7 has a Zener structure discussed above, which leads to a specific reaction as current is applied, in the form of a negative resistance. This decreases exponentially with the voltage across the diode, leading to the Zener-Knee characteristic which the 1PMT5920/TR7 follows. This phenomenon is the basis of its working principle.

The 1PMT5920/TR7 has a series of values associated with it, such as the maximum peak reverse voltage and the maximum zener current, which help give a better indication of its working limits. A maximum peak or surge current of 200 mA is also defined. It is designed to be used in ambient temperatures ranging from -55 °C to +150 °C with no fundamental differences in characteristics.

The 1PMT5920/TR7 is a low-power Zener diode, with a maximum average forward current of 297 mA and a maximum peak or surge current of 200 mA. It is most commonly used as a flyback diode across an inductive load driven by a voltage source, and also in voltage regulators. It has a Zener-Knee characteristic, giving it a negative resistance to a voltage across it, and can operate at temperatures from -55 °C to +150 °C.
