Diodes – Zener – Single
The 1N5221B-TP is a single Zener diode composed of two semiconductor materials. It’s designed to prevent voltage from exceeding a level known as the “zener voltage”. When the voltage rises beyond this level, the diode contains the voltage within this level, protecting further components.
Application Field
The 1N5221B-TP diode can be used for different applications. It can be used in telecom systems, such as modems, to protect against voltage spikes. With its wide range of power ratings and a wide variety of features, the 1N5221B-TP can be used in LEDs and LED drivers, such as LED street lights or household lighting. In security systems, the device can be used to control voltage or used as a sensing device. Additionally, it can be used as a switch in systems such as radar detection and unmanned aerial vehicles.
Working Principle
The Zener diode operates utilizing the reverse breakdown voltage of a semiconducor diode. It also acts as a voltage regulator by providing a constant voltage over a wide range of power. The principle of the 1N5221B-Tp device (as with other Zener diodes) is that when the forward-bias voltage is increased to a value that exceeds the Zener voltage, the diode is said to breakdown in the reverse-bias direction. This is where the device derives its name.
The diode is forward biased until the Zener voltage is reached, at which point the diode will switch to the reverse-biased state. This Zener voltage is determined by the materials/construction of the diode, and is set when the device is manufactured. It is worth noting that the Zener diodes’ characteristics differ from those of a regular diode. In the forward direction the voltage increases to its breakdown voltage level, while in the reverse-biased direction it decreases to 0 V.
When the diode is in the reverse-biased state, it becomes a voltage regulator and will be able to maintain that voltage. The current of the diode can be adjusted via the control of the reverse-biased voltage. In essence, the reverse voltage is adjusted according to the current passing through the diode.
In a high voltage application, 1N5221B-TP can allow the control of a given voltage level as well as other equipment, such as in the application of power converters, power regulators, and of course surge protection.
