TZM5222B-GS18 application field and working principle

The TZM5222B-GS18 is a single Zener diode developed by COMILOG CATV LTD. It is a semiconductor device composed of a single PN junction that operates in a reverse-biased state. It uses a highly doped p-type silicon as the Anode and an n-type silicon layer as the Cathode, allowing current to pass in both forward and reverse bias direction. By utilizing a reverse bias electrical field, it is designed to conduct current in the reverse direction, causing the free carriers on both sides of the diode to be pushed away from the depletion region, thereby allowing the diode to continue to carry current in the reverse direction.

The TZM5222B-GS18 has a maximum forward current rating of 250 mA, a maximum reverse voltage of 5.6V, and a maximum power dissipation of 1 watt. Its Zener voltage is 2.2 volts, with a standard tolerance of +/- 5%. It has a forward voltage of 0.7V at a bias current of 10mA. At high current, the diode has a temperature coefficient value of -0.05%. It can handle high surge currents and has a wide temperature range of -40oC to +125oC.

The TZM5222B-GS18 is designed primarily for use as a voltage regulator in a wide range of applications, including DC/DC converters, power supplies, and medical devices. It can also be used in signal processing and signal control systems, where it is used to protect other semiconductor components from over-voltage stress due to voltage transients and electrical switching. In addition, the diode can be used in the stabilisation of voltages in oscillators, other analog and digital circuitries, and in series-regulating circuits.

The TZM5222B-GS18 works by regulating the output voltage at a predetermined Zener voltage value. A Zener breakdown occurs when the voltage across the diode exceeds the Zener voltage rating. This breakdown causes current to flow from anodeto cathode of the diode. The diode then acts as a flywheel tending to absorb the excess voltage and regulating the output voltage to a steady voltage value. The diode has a built-in voltage stand-off capability that resists the application of higher voltages to the diode, thus maintaining the predetermined Zener voltage value.

In summary, the TZM5222B-GS18 is a single Zener diode developed by COMILOG CATV LTD designed for many electrical applications. This diode can handle up to 250 mA of forward current and with a voltage rating of 5.6V and its Zener voltage being 2.2V. It is a foolproof diode used to maintain a steady voltage in oscillators, circuitries, and in series-regulating circuits, among many other applications.
