Overview
The MCR100-8 A1G is a Silicon Controlled Rectifier (SCR) manufactured by Taiwan Semiconductor Corporation. It features a sensitive gate design suitable for direct triggering by microcontrollers and logic circuits. The device provides a reverse blocking voltage of 600V and an on-state current rating of 0.8A RMS at 80°C. It supports a surge current capability of 10A and offers dV/dt immunity of 20 V/µsec minimum at 110°C. The component is housed in a TO-92 plastic package with three terminals.
Feature Summary
- Sensitive gate architecture enables direct triggering from low-power logic sources
- High surge current handling capacity for robust operation
- Glass-passivated surface construction ensures reliability and uniformity
Applications
- Relay drivers
- Lamp drivers
- Small motor controls
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify the manufacturer marking matches Taiwan Semiconductor Corporation specifications. Confirm the suffix A1G corresponds to the intended pinout and tolerance requirements. Ensure the TO-92 package variant meets the thermal and mechanical constraints of the target assembly process.
Selection Notes
Select this component when a 600V blocking voltage and 0.8A continuous current are required in a compact TO-92 form factor. The sensitive gate characteristic makes it appropriate for applications driven directly by standard logic outputs without additional base drive circuitry.
Part Context
This part belongs to the MCR100 series of sensitive gate silicon controlled rectifiers. These devices are widely used in general-purpose line-powered consumer applications due to their cost-effectiveness and ease of integration into control circuits requiring simple switching functionality.
Replacement Considerations
Compatible substitutes include MCR100-8 variants from other manufacturers such as ON Semiconductor or Unisonic Technologies, provided they share the same TO-92 package, 600V rating, and 0.8A current specification. Verify pin compatibility before substitution.
