Overview
The 1N649 BK is a general-purpose rectifier diode manufactured by Central Semiconductor Corp. It features a peak reverse voltage of 600 V and an average forward current rating of 400 mA. The component utilizes a DO-7 through-hole package, suitable for standard PCB mounting. It operates within a temperature range of -65°C to +200°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA at rated voltage and a forward voltage drop of 1.1 V at 400 mA. The device is RoHS compliant and lead-free.
Feature Summary
- General-purpose rectification capability for power supply and signal applications
- High thermal stability with extended operating temperature range up to 200°C
- Low reverse leakage current ensuring efficient blocking performance
- Robust construction in a DO-7 axial leaded package
Applications
- General purpose rectification in power supplies
- Signal clipping circuits
- Current steering applications
Procurement Notes
Verify the specific suffix 'BK' against the manufacturer's official datasheet to confirm material composition and plating specifications. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the DO-7 package dimensions match the target PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when a 600 V reverse voltage rating and 400 mA continuous current are required in a through-hole configuration. Consider the high junction temperature limit for environments with limited cooling. Compare forward voltage characteristics against alternative small-signal diodes if low-loss conduction is critical for the specific circuit design.
Part Context
This part belongs to the single diode category from Central Semiconductor Corp. It serves as a robust discrete semiconductor solution for basic rectification tasks. The DO-7 package offers mechanical durability compared to smaller surface-mount alternatives. It is distinct from Zener or regulation diodes due to its unidirectional conduction properties.
Replacement Considerations
Public confirmed substitute part numbers: 1N649-1 (Microchip Technology). Verify pinout compatibility and thermal ratings when substituting.
FAQ
