- Designed for use in sensing circuits and control systems
- Through-hole mounting style with Tin/Lead plating
Applications
- Sensing circuit applications
- Control systems
- Industrial switching modules
Procurement Notes
Verify the exact part number includes the 'TIN/LEAD' suffix to ensure correct terminal plating specifications. Confirm that the hermetically sealed package aligns with the required environmental standards for the target application. Check current lifecycle status as some variants may be obsolete or subject to long production lead times.
Selection Notes
Select this component when hermetic sealing is mandatory for reliability in harsh conditions. Ensure the through-hole form factor fits the PCB layout constraints. Verify that the SCR's voltage and current ratings meet the specific load requirements of the control system design before finalizing the selection.
Part Context
This part is part of Central Semiconductor's range of discrete semiconductor devices. The 2N3670 specifically addresses the need for durable, sealed thyristors in critical infrastructure. It complements other SCRs like the 2N3669 within the same product line, offering standardized performance for general-purpose high-reliability switching tasks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official cross-reference guides or manufacturer datasheets for equivalent hermetically sealed SCRs if direct replacement is necessary.
