The CMPS5064 is a silicon controlled rectifier (SCR) manufactured by Central Semiconductor Corp. SCRs are semiconductor devices that act as electronic switches. Once triggered, they latch into the 'on' state and remain conducting until the current through them is reduced below a certain threshold (the holding current). The CMPS5064 is designed for a variety of applications where controlled switching of AC or DC power is required.

Technical Specifications

The CMPS5064 is housed in a through-hole TO-92 package, facilitating easy mounting on printed circuit boards (PCBs). It can withstand a repetitive peak off-state voltage of 400V, making it suitable for standard AC line voltages. The SCR can handle an RMS on-state current of 0.8A, and it requires a gate trigger current of only 200 μA to initiate conduction. The device is designed to operate within a temperature range of -65°C to +125°C.

Important Considerations: Proper heat sinking may be required for high-current applications. Ensure the gate trigger signal is sufficient to reliably turn on the SCR. Refer to the manufacturer's datasheet for complete specifications, application guidelines, and thermal considerations.
