Overview
The MCR100-6G is a sensitive gate Silicon Controlled Rectifier (SCR) from the MCR100 series, manufactured by onsemi. It features a peak repetitive off-state voltage of 400 V and an on-state RMS current rating of 0.8 A at 80°C. The device supports a peak non-repetitive surge current of 10 A and operates within a junction temperature range of -40 to 110°C. Packaged in a TO-92 (TO-226AA) plastic housing with straight leads, it includes glass-passivated surfaces for reliability. The 'G' suffix indicates a lead-free package compliant with environmental standards.
Feature Summary
- Sensitive gate architecture enables reliable triggering by microcontrollers and logic circuits
- Glass-passivated surface construction ensures uniformity and long-term reliability
- High dV/dt immunity rated at a minimum of 20 V/µs at 110°C
- Lead-free packaging available for environmentally compliant assembly
Applications
- Relay and lamp drivers in line-powered consumer electronics
- Small motor control circuits
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package style and shipping configuration. Confirm that the Pb-free designation aligns with project requirements. Validate component authenticity through authorized distribution channels. Ensure storage conditions remain within specified limits prior to soldering. Review the latest datasheet revision for any updates to maximum ratings or thermal characteristics.
Selection Notes
Select this component when a 400 V blocking voltage and 0.8 A RMS current capacity are required. The sensitive gate design is optimal for applications driven by low-current logic outputs. Evaluate thermal management needs based on the 75 °C/W junction-to-case resistance. Consider the TO-92 package constraints for high-volume automatic insertion processes. Verify dV/dt requirements against the 20 V/µs minimum specification at elevated temperatures.
Part Context
The MCR100-6G belongs to the MCR100 series of reverse blocking thyristors designed for high-volume consumer applications. This series offers various voltage ratings ranging from 100 V to 600 V, distinguished by numeric suffixes. The MCR100-6 variant specifically provides 400 V blocking capability. The series is engineered for cost-effective integration into AC line-powered devices requiring robust switching performance.
Replacement Considerations
Cross-reference with other MCR100 series variants such as MCR100-3, MCR100-4, or MCR100-8 for different voltage ratings. Check equivalent SCRs from other manufacturers like STMicroelectronics or Unisonic Technologies with matching 0.8 A RMS and 400 V specifications. Ensure pinout compatibility and thermal resistance values match the existing design constraints before substitution.
