Description
M1L43 is 800V, 1A, Thyristor.
Thyristors have three or four layers of alternating p-type and n-type semiconductor material and are typically triggered into operation by a small current applied to the gate terminal.
Once triggered, the thyristor remains in the “on” state until the current flowing through the device is interrupted or the voltage across the device falls below a certain level.
Thyristors have several advantages over traditional mechanical switches, including high reliability, fast switching speeds, and the ability to handle high currents and voltages.
Features:
1. Repetitive Peak Off−State Voltage : VDRM = 800V
2. R.M.S. On−State Current : IT (RMS) = 1A
Applications:
1. AC POWER CONTROL
