Overview
The MCR100-4G is a sensitive gate silicon controlled rectifier (SCR) from the MCR100 series, manufactured by onsemi. It features a reverse blocking thyristor structure housed in a TO-92 package. The device supports a peak repetitive off-state voltage of 200 V and an on-state RMS current rating of 0.8 A at 80°C. It offers high surge current capability up to 10 A and includes specified minimum and maximum values for gate trigger current, gate trigger voltage, and holding current to facilitate design integration.
Feature Summary
- Sensitive gate architecture enables triggering by microcontrollers and logic circuits
- Glass-passivated surface ensures reliability and uniformity
- Immunity to dV/dt with a minimum rating of 20 V/µs at 110°C
Applications
- Relay drivers
- Lamp drivers
- Small motor controls
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify the specific suffix 'G' indicates a lead-free package configuration as defined in the ordering information table. Confirm the device code '4' corresponds to the 200 V rating variant. Ensure the TO-92 package style matches the required automatic insertion equipment specifications. Check for RoHS compliance documentation if required by local regulations.
Selection Notes
Select this component when a 200 V blocking voltage and 0.8 A RMS current capacity are required. The sensitive gate feature makes it suitable for low-power logic control applications. Consider thermal derating curves for case temperatures exceeding 80°C. Verify that the 10 A surge current capability meets the circuit's transient requirements.
Part Context
The MCR100-4G belongs to the MCR100 series of sensitive gate SCRs. Other variants in the series include MCR100-3 (100 V), MCR100-6 (400 V), and MCR100-8 (600 V). All share similar physical packaging and general characteristics but differ in their peak repetitive off-state voltage ratings.
Replacement Considerations
Direct substitutes within the same series include MCR100-3G, MCR100-6G, and MCR100-8G, provided the voltage rating aligns with the application needs. Cross-manufacturer replacements must match the TO-92 package, 0.8 A RMS current, and 200 V blocking voltage specifications.
