Overview
The MCR218-006 is a silicon controlled rectifier (SCR) from the MCR218 series, manufactured by onsemi. It features glass-passivated junctions and utilizes a TO-220AB package for low thermal resistance and high heat dissipation. The device supports an on-state RMS current of 8.0 A at a case temperature of 70°C with a 180° conduction angle. Peak repetitive off-state voltage ratings are available up to 400 V. It operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Glass-passivated junctions designed for reliability and uniformity
- TO-220 construction providing low thermal resistance and high durability
- Reverse blocking thyristor capability for half-wave AC control applications
Applications
- Motor controls
- Heating controls
- Power supplies
Procurement Notes
Verify the specific suffix code against the datasheet to confirm the exact voltage rating. The 'MCR218-006' designation does not match the standard 'MCR218-2G', 'MCR218-4G', or 'MCR218-6G' part numbers listed in the official documentation. Ensure the component matches one of these verified part numbers before procurement.
Selection Notes
Select based on the required peak repetitive off-state voltage, which ranges from 50 V to 400 V across the series. Consider the thermal management requirements, as the device relies on the TO-220AB package for heat dissipation. Verify that the gate trigger characteristics align with the driving circuit capabilities for reliable switching.
Part Context
This component belongs to the MCR218 family of reverse blocking thyristors produced by onsemi. These devices are engineered for high-volume consumer applications requiring reliable solid-state switching. The series includes variants differentiated primarily by their voltage blocking capabilities while maintaining consistent current handling and packaging standards.
Replacement Considerations
Compatible replacements include MCR218-2G, MCR218-4G, and MCR218-6G. Select the variant that matches the required voltage rating: MCR218-2G for 50 V, MCR218-4G for 200 V, or MCR218-6G for 400 V.
