BZT52B20-G RHG Working Principle

The diode works by utilizing the Zener breakdown phenomenon, which occurs when an electric field is applied across a semiconductor junction with a reverse-biased voltage greater than the breakdown voltage. This causes the junction to break down, allowing current to flow in one direction, and preventing current flow in the other direction.

The breakdown voltage of the BZT52B20-G RHG is set at 20V, with a maximum surge reverse voltage of 200V. It can handle up to 1A of current, and its operating temperature ranges from -65°C to +150°C. Furthermore, it has a maximum leakage current of 10uA. The diode is packaged in a plastic DO-214AB package, which is a small-sized, two-lead, axial-leaded package with a compact design.

In summary, the BZT52B20-G RHG is a single Zener diode designed for switching mode power supply and power switching applications. It utilizes the Zener breakdown phenomenon, allowing current to flow in one direction and preventing current flow in the other direction. It has a 20V breakdown voltage, with maximum surge reverse voltage of 200V, a maximum current of 1A, and an operating temperature range from -65°C to +150°C. The diode is packaged in a DO-214AB two-lead, axial-leaded package.
