MCR100-6 THYRISTOR
Share :
The MCR100-6 is a small, low-current Silicon Controlled Rectifier (SCR), also known as a thyristor. While not a main power component like the IGBTs, it is often used in precise, low-cost protection circuits within the control logic of a power system.
Here are its core specifications and relevance to the Canvas:
Type: Silicon Controlled Rectifier (SCR) / Thyristor.
Voltage Rating (V_RRM):400 V (Repetitive Peak Reverse Voltage).
Current Rating (I_T):0.8 A (RMS On-State Current).
Gate Trigger Current (I_GT): Low, typically 20uA (easily triggered by logic).
Package: Small, low-power package, often TO-92 (through-hole).
Relevance to Safety/Protection: Due to its latching property (once triggered, it stays ON until the current drops below a holding current), the MCR100-6 is excellent for implementing fault-latching protection circuits. It could be used in the control circuitry to:
Crowbar/Latching Fault: Latch the system into a safe shutdown state after the 120C thermal switch is tripped, or an overcurrent condition is detected. This ensures the protection mechanism is robust and does not reset until manual intervention, which adheres to stringent safety Standards.
Simple Overvoltage Protection: Act as a crowbar circuit to safely blow a fuse if the control voltage exceeds a certain threshold.
