Overview
The MCR100-6 A1G is a Silicon Controlled Rectifier (SCR) manufactured by Taiwan Semiconductor Corporation. It features a repetitive peak off-state voltage of 400V and an RMS on-state current rating of 0.8A. The device utilizes a sensitive gate architecture, enabling triggering by microcontrollers and logic circuits. It is housed in a TO-92 package with three terminals. The component is designed for high-volume consumer applications, offering reliable performance in line-powered environments.
Feature Summary
- Sensitive gate structure allows direct interfacing with low-power logic circuits
- Robust construction suitable for line-powered consumer electronics
- Halogen-free packaging compliant with environmental standards
Applications
- Relay drivers
- Lamp drivers
- Small motor controls
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify the manufacturer designation as Taiwan Semiconductor Corporation against the specific datasheet provided by the supplier. Confirm the suffix A1G corresponds to the intended pinout and marking configuration. Ensure the component meets RoHS and halogen-free requirements if specified for the target assembly process.
Selection Notes
Select this component when a compact SCR with sensitive gate triggering is required for low-current switching applications. The 0.8A RMS rating suits light loads, while the 400V blocking voltage provides adequate margin for standard AC line voltages. Consider the TO-92 package constraints for thermal management in enclosed designs.
Part Context
This part belongs to the MCR100 series of sensitive gate silicon controlled rectifiers. These devices are widely used in general-purpose switching applications due to their ease of drive and reliability. The MCR100-6 variant specifically offers a 400V voltage rating, distinguishing it from other ratings within the same current-capable family.
Replacement Considerations
Cross-reference with MCR100-6 equivalents from other manufacturers such as Unisonic Technologies or ON Semiconductor. Verify that substitute parts maintain the same TO-92 pinout and sensitive gate characteristics to ensure circuit compatibility without redesign.
