PTZTE256.2A is a single series of Zener diodes that are designed to provide a variety of electrostatic protection solutions. The devices are available in a wide range of voltages that can be used to provide a consistent voltage level in presence of airborne surges and transient peak voltages.

The PTZTE256.2A features an integrated pre-terminated ITO (Insulated Termination Make) electrode that offers a self-protecting design. Its P (zener) anode feature helps in providing an integrated electrostatic surge protection without the need for external components. This makes PTZTE256.2A ideal for applications in computers, servers, peripherals and any kind of electronic device that needs protection against electrostatic discharge.

PTZTE256.2A features maximum power dissipation of 0.4 watts, maximum breakdown voltage of 25 volts, and maximum clamping voltage of 40 volts. It is capable of handling up to 200 mA of average current with a peak pulse current of 1000 mA.

When subjected to an electrostatic strike such as a spark, the P+ (zener) anode produces a reverse voltage that quickly clamps the voltage to an operational level to protect vulnerable components and circuits. The P+ also works in reverse bias, where it absorbs the surge power and effectively reduces its peak of the transient. In addition, the device is self-limiting, meaning that when subjected to shocks, the P+ will limit the current to the electrostatic discharge level, thereby preventing a large amount of energy from being passed to the circuit.

This Zener Diode is well suited for applications in noise suppression, overvoltage suppression, and grounding. The device can be used in a variety of applications where electrostatic surge protection is needed such as USB ports, AC/DC adapters, monitors, laptops and TV sets.

PTZTE256.2A is a robust solution that provides reliable protection for vulnerable electronics. The device is also cost effective, and its integration of pre-terminated ITO electrodes eliminate the need for the costly installation of external components.
