Diodes - Zener - Arrays: BZX84C36TS-7-F application field and working principle

BZX84C36TS-7-F is a type of Zener Array produced by ON Semiconductor. It contains two serial interconnected Zener diodes, both of which are manufactured with a protective glass passivation process, which helps to ensure reliable operation over time. It also offers protection against transient surges, with a peak pulse power of up to 400 W atts and a surge current of 20 amperes. Additionally, it has an operating temperature range from -55 °C to +175 °C.

The BZX84C36TS-7-F Zener Array is designed for use in a wide range of applications. It can be used in circuits that require voltage regulation, such as DC-DC converters, voltage regulator modules (VRM) or AC/DC switching mode power supplies (SMPS). Additionally, its use in high frequency switching, such as in switch mode power supplies, class-D amplifiers and automotive applications, is also very common. It can also be used as a fast recovery regulator clamp in circuits with high transient voltages.

In terms of its working principle, the BZX84C36TS-7-F Zener Array is simply two Zener diodes wired in series. The Zener diode is a silicon-based semiconductor device which has a characteristic that allows current to flow in one direction, in a similar way to a normal diode. However, when the voltage applied exceeds the threshold value, known as the Zener voltage, the device begins to conduct in the opposite direction. This means that it can regulate voltage by allowing excess current to flow in the reverse direction, thus limiting the voltage.

The Zener diodes allow for the device to maintain its set voltage by ensuring the two diodes have the same Zener voltage. If one diode is exposed to a higher voltage, it will begin to conduct and the voltage across both diodes will equalize. This ensures that the output voltage remains constant, irrespective of external fluctuations or ripple current.

Furthermore, the BZX84C36TS-7-F Zener Array can be used in order to protect sensitive circuits from overvoltages. When an overvoltage is applied to the device, the Zener diodes will regulate the voltage and limit current flow, thus protecting the circuit. Furthermore, the Zener array can protect against transient surges, as it is designed to dissipate the energy by regulating the voltage.

In conclusion, the BZX84C36TS-7-F Zener Array is a versatile and reliable device that can be used in a wide range of circuits and applications. Its two series-connected Zener diodes regulate voltage by allowing excess current to flow in the reverse direction, thus providing accurate voltage regulation and protection against overvoltages and transient surges.
