Overview
The MCR100-5 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 sensitive gate triggering technology, allowing for operation with limited gate current. It is housed in a DO-214AC (SMB) surface-mount package. The component operates within a junction temperature range of -40°C to 125°C and is designed for applications requiring compact form factors and reliable switching performance.
Feature Summary
- Sensitive gate triggering capability suitable for low-current drive applications
- Surface-mount construction in a compact SMB package
- Robust thermal performance with high junction temperature tolerance
Applications
- Small motor control circuits
- Gate driver stages for larger SCRs
- Sensing and detecting circuits
Procurement Notes
Verify the specific suffix 'A1G' against the manufacturer's official datasheet to confirm pinout orientation and marking codes. Ensure the procurement channel provides traceability documentation consistent with Taiwan Semiconductor Corporation standards. Confirm RoHS compliance status through the latest product release notes.
Selection Notes
Select this component when a surface-mount SCR with sensitive gate requirements is necessary. Compare the 400V blocking voltage and 0.8A current rating against circuit demands. Consider the DO-214AC footprint constraints during PCB layout. Evaluate thermal management needs relative to the specified junction temperature limits.
Part Context
This part belongs to the MCR100 series of plastic-encapsulated silicon controlled rectifiers. The series is characterized by its suitability for high-volume manufacturing and general-purpose switching applications. The MCR100-5 variant specifically denotes the 400V voltage class within this family.
Replacement Considerations
Cross-reference with other manufacturers offering DO-214AC packaged SCRs with similar 400V/0.8A ratings. Verify that substitute parts maintain compatible sensitive gate trigger characteristics. Check for identical pinout configurations to ensure direct board compatibility without redesign.
