Introduction

The 1EZ140D/TR12 Diode is a single Zener diode manufactured by Panjit Semiconductors, one of the world\'s leading manufacturers of semiconductor technologies. Designed for a wide range of applications, the 1EZ140D/TR12 Diode has a high breakdown voltage rating and outstandingly low leakage. This makes it a suitable choice for power supply and voltage control applications.

Application Field

The 1EZ140D/TR12 Diode is suitable for use in high voltage DC-DC converter applications, in addition to other devices requiring voltage regulation or low-leakage performance. Its high breakdown voltage rating makes it an ideal choice for voltage switching and protection applications, as well as communications and information systems. It is also suitable for use in power supplies, such as PCs and servers.

Working Principle

The 1EZ140D/TR12 Diode works by using a reversed biased voltage across an ultra-high resistance junction. This junction allows small current to flow and ensures the diode maintains its constant voltage rating. When the voltage across the diode exceeds its rated breakdown voltage, it will switch off and present a near open-circuit condition. This helps protect the circuit from overvoltage conditions.By adjustment of the Zener voltage rating, the 1EZ140D/TR12 Diode can be used as a voltage regulator, allowing a voltage supply to be regulated to a predetermined voltage. The device can also be used to allow current to flow freely in one direction, and prevent it from flowing in the other direction, due to its diode characteristics.

Conclusion

The 1EZ140D/TR12 Diode is used in a wide range of applications, ranging from power supplies and communications to voltage regulation and protection. With its low leakage and high breakdown voltage rating, this diode is a suitable choice for any application requiring voltage regulation or low leakage performance. Its working principle is based on reversed biased voltage across an ultra-high resistance junction, which allows for small current to flow and permits the diode to maintain its constant voltage rating.
