Working Principle

The BZT52B12-G RHG is a single Zener diode designed with a low capacitance. The capacitance is achieved through a process during the manufacturing of the device that reduces the space between the cathode and anode. This helps reduce the capacitance and increase the switching speed.

The working principle of the BZT52B12-G RHG is based on the voltage-dependent breakdown of a PN junction diode. A PN junction diode is a semiconductor device consisting of a P-type semiconductor material adjacent to an N-type semiconductor material. When a voltage is applied across the PN junction, the electrons and holes on either side increase in mobility and tunnel through the junction. This increases current flow through the diode, resulting in a voltage drop across the diode.

The BZT52B12-G RHG is designed for low voltage and high speed. The voltage rating is 12V ± 5% and the operating temperature range is -55°C to +125°C. The maximum current rating is 0.5mA and the maximum surge forward current rating is 4.2A. The switching speed of the diode is 500ns. The diode is also designed to have a reasonably low capacitance of 1.2pF.
