TFZVTR6.2B is a single zener diode which is mainly used in the application of reverse-voltage and over-voltage protection. The device has a cathode band for easy identification, and its baseline reverse voltage is 6.2V. It is widely used in automotive, industrial and consumer electronics applications.

The working principle of TFZVTR6.2B can be described as follows. When subjected to a forward voltage of less than 6.2V, current passes through it, however when an excessive voltage is applied, it starts clamping the voltage to a certain level, thus avoiding the equipment from damage. The breakdown voltage of the diode is 6.2V and the Zener knee voltage (ZKV) around 6.045V. At ZKV the device offers a very low leakage current (< 5mA @ 30°C).

The device’s Zener impedance is around 0.4Ω, which helps it achieve excellent stability and low capacitance, therefore making it suitable for a wide range of applications such as reverse battery, load dump and transients protection, overvoltage clamping, circuit stabilization, and hot plugging protection. It is also used in automotive ECU and data-signal line protection.

In summary, TFZVTR6.2B is an ideal single zener diode for reverse-voltage and over-voltage protection. It has a 6.2V breakdown voltage and very low leakage current (< 5mA @ 30°C). It offers excellent stability and low capacitance, and is suitable for a wide range of applications such as reverse battery, load dump and transients protection, overvoltage clamping, circuit stabilization, and hot plugging protection.
