1PMT5922AE3/TR7

The 1PMT5922AE3/TR7 diode is a single Zener diode, which is used to provide protection from voltage spikes and ESD.

Application Field

The 1PMT5922AE3/TR7 is generally used as a voltage regulator or a surge protection device. When connected in reverse polarity, this diode works as a Zener diode and clamps the voltage to its rated breakdown voltage (Vz). This feature makes it useful in surge protection, voltage stabilization, current limiter, and many other fields. It has a wide operating voltage range of 3.3 to 200 volts, making it well-suited for use in a variety of applications.

Working Principle

The 1PMT5922AE3/TR7 operates on the Zener breakdown principle. At normal conditions, the anode-cathode junction works as an open circuit and does not allow current to pass through. However, when the applied voltage is more than the breakdown voltage (Vz), the electrons move from cathode to anode, allowing current to pass through. This effect is called the reverse bias Zener breakdown and it is used in the diode to clamp the voltage to its rated breakdown voltage.

For greater convenience, the 1PMT5922AE3/TR7 is also available in the SMD or surface mount package. This type of diode can be soldered directly onto a Printed Circuit Board (PCB). This makes it ideal for applications where a high component count is necessary.

Conclusion

The 1PMT5922AE3/TR7 is a single Zener diode typically used in applications requiring a voltage clamp or surge protection. It operates on the Zener breakdown principle to limit the voltage to its rated breakdown voltage. Its wide operating voltage range makes it suitable for use in a variety of applications ranging from voltage regulation to surge protection. Furthermore, the SMD version of the diode can be soldered directly to the PCB for greater convenience.
