Introduction to 1EZ120D5E3/TR8

1EZ120D5E3/TR8 is a type of diode (Zener Diode) which is widely used in various applications and provides electrical protection from transient voltages. 1EZ120D5E3/TR8 is a single, low-power Zener diode that offers good reverse voltage protection and low-cost solution for electronic device protection against overvoltage disruptions.

Application Field

1EZ120D5E3/TR8 is mainly used in automotive and industrial applications, such as Power Supply in Battery Chargers, Telecommunication Systems, Automotive Applications, and Industrial Controls. 1EZ120D5E3/TR8 also finds its application in LED lighting, LED driver circuits, and even laser diode driver circuits.

Working Principle

The principle at work in 1EZ120D5E3/TR8 is that it behaves like a normal diode when the applied reverse voltage is below its rated breakdown voltage. That is to say, when current passes through it, a small fraction of the current (called the Zener current) is diverted and passes through the Zener barrier and leaves the diode at the open-circuited node.However, when the applied reverse voltage increases above the rated breakdown voltage, the Zener current increases rapidly, thus resulting in a low impedance path between the cathode and anode. This forms a low-resistance channel between the cathode and anode and a constant voltage across the diode. This voltage is referred to as the Zener voltage. Therefore, when reverse voltage increases above the rated breakdown voltage (which is usually 6.8V, 7.5V, or 8.2V), 1EZ120D5E3/TR8 will establish a low-resistance path, thus diverting the majority of the current, thus protecting the electronic device under protection from further overvoltage disruptions.

Conclusion

1EZ120D5E3/TR8 is a single, low-power Zener Diode that, upon encountering a reverse voltage higher than the breakdown voltage, will dissipate very little power, thus offering a good and cost-effective solution for electronic device protection against overvoltage disruptions. 1EZ120D5E3/TR8 can be used in various automotive and industrial applications.
