BZT52C8V2T-7

The BZT52C8V2T-7 is an unidirectional zener diode provides consistent and reliable performance at a low-cost. This particular diode is specified for general-purpose use with a planar glass passivation technology. The diode is small in size with a lead pitch of 1.2 mm.

This zener diode device is a part of the range of low-voltage, precision, low-power zener diodes. Designed in a glass passivation based package, the typical application field of this diode is to provide a stable voltage at an established level. Other applications include clipper circuits, as well as many other general rectifier and switching circuit configurations.

The working principle of the BZT52C8V2T-7 is quite straightforward and can be described simply by understanding the difference between how a regular diode and a zener diode works. As with most other diodes, the BZT52C8V2T-7 also works by conducting current in one direction and preventing it from flowing in the opposite direction. This effect is due to the p-n junction and the resulting rectification current paths.

However, what sets a zener diode apart is that it serves a dual purpose - it can also be used to maintain a stable voltage level. This happens when the reverse bias given to the diode is sufficiently large that it causes it to break down and let current ‘leak’ through it. This reverse leakage current is proportional to the applied voltage, which therefore allows the zener diode to provide a regulated reference voltage.

The zener voltage of any zener diode is calculated using the equation VZ = VZ(min) + [Iz@max]. This equation states that the zener voltage of the diode is equal to its rated zener voltage plus a certain amount of current, known as the zener current, that must pass through the diode before its zener voltage is reached.

In the case of the BZT52C8V2T-7, the zener voltage is 8 volts and the maximum zener current is 2.0 mA. Hence, the zener voltage of the diode can be calculated as 8 + (2 x 0.002) = 8.004 volts. This is the voltage that will be maintained across the diode even if the voltage on either side is changed. This makes it possible to use the BZT52C8V2T-7 as a reference voltage source in many different circuit configurations.

Thus, the BZT52C8V2T-7 is a single unidirectional zener diode that offers consistent and reliable performance, making it suitable for a wide range of general-purpose electronic applications. Its working principle is based on the ability of the device to maintain a stable voltage level even when the input voltage changes, making it an excellent choice for use in circuits requiring a reference voltage.
