An SCR (Silicon Controlled Rectifier) is a specific type of thyristor. While 'thyristor' is the broader family, SCRs are the most common type used for power control.

Power control modules for industrial rectification and switching
What are Thyristor & SCR Modules components?
Thyristor and SCR modules are power semiconductor devices used for high-current switching and rectification. They are essential in motor drives, soft starters, and industrial power supplies. Selection hinges on peak repetitive voltage (VDRM/VRRM) and average forward current (ITAV).
How to Choose Thyristor & SCR Modules Components
Focus on the electrical and thermal constraints of your power stage.
Voltage Rating
Ensure VDRM/VRRM exceeds your peak line voltage plus a safety margin for transients.
Current Capacity
Match the ITAV rating to your load, accounting for duty cycle and ambient temperature.
Module Topology
Select between single SCR, dual SCR, or bridge configurations based on your circuit architecture.
Thermal Resistance
Evaluate Rth(jc) to determine heatsink requirements for reliable operation.
Isolation Voltage
Verify the baseplate isolation voltage to ensure safety and compliance with isolation standards.
