Diodes are devices that allow currents to flow in one direction and inhibit currents from flowing in the opposite direction. Zener diodes, also known as spike diodes, are special types of diodes that allow currents to flow in the backward direction when the voltage reaches a certain level. This means that when positive voltages are applied, the diode will allow current to flow in the reverse direction, eventually causing the current to saturate. The TFZVTR9.1B is a single Zener diode, which has an optimized design to meet the stringent requirements of noise immunity and offer improved reliability.

Application Field

The TFZVTR9.1B Zener diode is designed to be used in low voltage applications, so it is most often used in electronic equipment such as televisions, computers, and mobile phones. It is especially useful for providing noise immunity in communication systems, as it quickly absorbs any interference or noise that affects the signal. It is also used in power electronics applications such as power supplies and driver circuits, where noise immunity and filtering are critical.

Working Principle

The TFZVTR9.1B is an unidirectional Zener diode, meaning that it allows current to flow in the forward direction and prevents it from passing in the opposite direction. When a constant voltage is applied to the diode, it causes a change in its electrical resistance, forcing current from the positive side of the diode to the negative side. This results in a voltage drop, which is referred to as “Zener voltage”. This voltage drop is what allows for noise immunity and filtering in communication systems and power electronics.

When the reverse voltage of the diode becomes too high, it triggers a breakdown and creates a large surge of current. This sudden current then causes the voltage in the diode to become stable, which in turn results in the noise or interference being effectively blocked.

The TFZVTR9.1B is designed to operate at low voltages (5V to 30V), while providing excellent noise immunity and improved reliability. It features an optimized design that makes it suitable for use in a wide range of applications.
