7M-50.000MAHE-T

With the development of industrialization and the extensive application of electricity in industry, the study of electric control and power electronics has received increasingly widespread attention. Among them, switching power supplies, thyristors and related supporting components are very important. MAHE-T series high and low voltage silicon controlled rectifiers (SCR) belong to one kind of widely used thyristor family.

7M-50.000MAHE-T Application Field and Working Principle

7M-50.000MAHE-T series SCR products have higher voltage and current, small size and high efficiency which is widely used in inverter, frequency conversion and energy-saving devices, power switch control, train speed control and other fields.

SCR’s latching action means that it can start and interrupt the current without additional control devices. Its main principle is: When the device is in the forward blocking state, if the gate current is greater than the characteristic value, the SCR is forcibly turned on, and the anode current flows to the cathode through PN junction. At this time, the SCR will latch, and the gate action no longer affects the current. However, if the voltage between the anode and cathode is reversed and the current is reduced to 0, the device is in the reverse blocking state.
