Overview
The MCR100-3 A1G is a Silicon Controlled Rectifier (SCR) manufactured by Taiwan Semiconductor Corporation. It features a 100V repetitive peak forward and reverse blocking voltage, with an on-state RMS current rating of 0.8A at 80°C. The device utilizes a sensitive gate design, allowing triggering by microcontrollers and logic circuits. It is housed in a TO-92 package and operates within a junction temperature range of -40°C to +110°C.
Feature Summary
- Sensitive gate architecture enables direct triggering from low-power logic circuits
- High surge current capability supports transient load conditions
- Glass-passivated surface ensures reliability and uniformity
Applications
- Relay and 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 marking code 'A1G'. Confirm the package type is TO-92 and the voltage rating is 100V. Ensure compliance with RoHS standards if required for the assembly process.
Selection Notes
Select this component when a 100V blocking voltage is sufficient for the application. The 0.8A RMS current rating suits low-power switching tasks. Consider the sensitive gate feature for compatibility with standard logic outputs without additional drive circuitry.
Part Context
This part belongs to the MCR100 series of sensitive gate silicon controlled rectifiers. The series includes variants with different voltage ratings, such as the MCR100-4 (200V) and MCR100-6 (400V). The MCR100-3 specifically provides the lowest voltage rating in the common lineup, suitable for lower voltage line-powered applications.
Replacement Considerations
Compatible substitutes include the MCR100-3 from other manufacturers like ON Semiconductor or Unisonic Technologies. Verify that the replacement maintains the 100V VRRM/VDRM rating and 0.8A IT(RMS) specification. Ensure the package footprint matches TO-92 dimensions.
