BZV85-C33,133 Discrete Semiconductor Products

The BZV85-C33, 133 is a single Zener diode designed for voltage regulation, clipping, and clamping applications. It is designed to conduct up to 3 amps of DC current, with a reverse breakdown voltage of 33.0 V ± 5%. It is equipped with a low reverse leakage current, low capacitance, and low forward voltage drop.

BZV85-C33, 133 is commonly used in electronics applications such as power supplies, motor controls, clocks, and diode-pumped solid state laser (DPSSL) systems. This diode is also suitable for over-voltage protection circuits, peak voltage clamping circuits, and pre-emphasis circuits. Its ability to handle up to 3 amps of current and its relatively low cost make it an excellent choice for consumer electronics and automotive applications.

Working Principle:The working principle of the BZV85-C33, 133 is the same as that of any other Zener diode. When the reverse voltage across the diode exceeds the breakdown voltage, it conducts current in the reverse direction, causing the voltage across the diode to remain constant. This is known as "Zener breakdown". The breakdown voltage of this diode is 33.0 V ± 5%.

The Zener diode is designed with an altered doping profile, which makes it capable of operating in the breakdown region. This altered doping profile enables the diode to maintain a more stable voltage when operating in this region. The current-voltage characteristics of the diode are such that the current is reverse proportional to the voltage drop, thus limiting the current passing through the device.

The BZV85-C33, 133 is designed with a low reverse leakage current of typically less than 3 mA, a low capacitance of typically less than 150 pF, and a low forward voltage drop of typically less than 0.53 V. This makes the diode suitable for high frequency applications, such as power supplies and motor controls. Additionally, the diode is able to withstand a maximum repetitive peak inverse voltage of 55 V and a maximum one-time applied peak inverse voltage of 100 V.

In conclusion, the BZV85-C33, 133 is a single Zener diode that is widely used in power supplies, motor controls, and clocks, as well as pre-emphasis circuits and peak voltage clamping circuits. Its ability to handle up to 3 amps of current, its low cost, and its stability in the breakdown region make it an excellent choice for many applications.
