How to maintain and maintain the 3P4MH Thyristor?
3P4MH Thyristor is a semiconductor device that consists of two P-type semiconductor layers and two N-type semiconductor layers, with three electrodes: anode (A), cathode (K), and control electrode (G). When a forward voltage is applied to the control electrode, the internal PN junction turns on, allowing current to flow from the anode to the cathode. This process is called "triggering" or "turning on." Once triggered, the current can continue to flow from the anode to the cathode until the voltage on the control electrode is removed or reduced to a certain level, and the PN junction will return to the blocking state.
As a high-performance, high-power semiconductor device, 3P4MH Thyristor has the following advantages:
