Diodes - Zener - Single

2EZ12D5-TP is a kind of single Zener diode developed by a famous semiconductor and specialty components manufacturer. The diode is designed with low voltage and high current capacity and is used in reverse bias to provide the most reliable protection against power surges and other forms of overvoltage.

Application Field

It has plenty of applications, such as ESD protection in computers, TVs, CRT monitors, cell phones, cameras and other electronic equipment, automotive circuit protection, voltage regulation in switching power supplies and other power control circuits. 2EZ12D5-TP is also used for protecting against static discharge in telecommunications and military applications.

Working Principle

When the voltage across the diode exceeds its breakdown voltage (Vz), a steep increase in the current begins to flow. The diode can take thousands of amperes during a split second while it moves into this operating state, the power involved being dissipated as heat. This high current quickly drops back to very low levels, overtemperature protection limiting the current during the typical avalanche to a much lower value.

Due to its superior high-current handling capacity and fast switching time, this diode has been widely used in protection and control circuits to reduce overvoltage caused by ESD, lightning, power supply surges, brownouts and other voltage transients. In addition, its special ceramic zinc-oxide package won’t affect by-products that can corrode printed circuit board components or reduce lifetime of insulating materials.

Characteristics

2EZ12D5-TP has a breakdown voltage (Vz) of 12V, with a zero-voltage resistance of 800 ohms or greater. It has a total thermal resistance of 536K/W, a DC current capability of 750mA, and a maximum power rating of 800mW. It is capable of sustaining high power pulses up to 1 microsecond. It is constructed of ceramic material, with a maximum operating temperature of 150°C. It has an enhanced surge tolerance and fast response time, making it suitable for high speed, high density designs.

Conclusion

The 2EZ12D5-TP single Zener diode is a reliable and efficient device used to protect circuits from overvoltage events. Its high current capability, low thermal resistance, and fast response time, make it ideal for a variety of applications. It is a superior choice for protecting, controlling, and regulating circuits from lightning, ESD, and voltage transients.
