Overview
The MCR8DCMT4G is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-volume industrial and consumer applications. It features an 800V rated repetitive off-state voltage (VDRM) and conducts a continuous on-state RMS current of 8A. The device is housed in a surface-mount DPAK-2 (TO-252-2) package. Key electrical parameters include a non-repetitive peak on-state current of 80A at 60Hz, a maximum holding current of 35mA, and a gate trigger voltage of 1.3V with a gate trigger current of 35mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Passivated die construction ensures reliability and uniformity under varying conditions.
- Low level triggering and holding characteristics facilitate efficient control circuitry design.
- Small surface mount footprint optimizes board space for compact designs.
Applications
- Motor control systems
- Process control circuits
- Temperature modulation controls
- Light and speed control applications
Procurement Notes
Verify the component authenticity by checking the manufacturer's marking code against official Littelfuse documentation. Confirm the RoHS compliance status and specific tape-and-reel packaging specifications required for automated assembly processes before finalizing procurement orders.
Selection Notes
Select this SCR for applications requiring robust surface-mount thyristor solutions with moderate current handling capabilities. Ensure the gate drive circuit can supply the specified trigger current and that the thermal management strategy supports the 125°C maximum junction temperature rating during operation.
Part Context
This component belongs to the MCR series of silicon controlled rectifiers from Littelfuse. These devices are engineered for cost-effective, high-volume production environments. The MCR8DCMT4G specifically addresses the need for reliable phase control in compact form factors common in modern consumer electronics and industrial equipment.
Replacement Considerations
Consult Littelfuse or ON Semiconductor datasheets for direct pin-compatible alternatives within the MCR series. Verify that any substitute part matches the 800V blocking voltage, 8A RMS current, and TO-252-2 package dimensions to ensure mechanical and electrical compatibility.
