Overview
The Central Semiconductor Corp 1N5305 BK TIN/LEAD is a silicon current regulator diode housed in a DO-35 glass package. It provides a regulated source current of 2mA with a maximum limiting voltage of 1.85V. The component features hermetic sealing and an isolated case connection, ensuring high reliability for critical applications. It operates within a temperature range of -65°C to +200°C and utilizes tin/lead terminations.
Feature Summary
- Hermetically sealed glass construction for enhanced environmental protection
- High reliability design suitable for critical circuit applications
- Constant current regulation over a wide voltage range
Applications
- Current limiting circuits requiring stable regulation
- Biasing networks for transistors and active components
- Protection circuits against excessive current flow
Procurement Notes
Verify the specific suffix 'BK TIN/LEAD' to confirm the terminal composition matches leaded requirements. Ensure the order specifies the hermetic seal variant if environmental resistance is mandatory. Cross-reference the manufacturer's datasheet for the 1N5283 series to validate electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 2mA current source is required in a compact axial-leaded form factor. The DO-35 package offers space efficiency compared to larger regulators. Consider the 1.85V limiting voltage to ensure compatibility with downstream component voltage ratings. Verify that the operating environment supports the specified thermal limits.
Part Context
This part belongs to the 1N5283 through 1N5314 series of silicon field effect current regulator diodes manufactured by Central Semiconductor. These devices are designed to provide constant current over a wide voltage range using a cost-effective DO-35 double plug case. The series emphasizes superior lot-to-lot consistency and special selections for critical applications.
Replacement Considerations
Equivalent parts include the 1N5305LEADFREE for lead-free compliance or the 1N5305BKLEADFREE for hermetic lead-free options. Standard JEDEC registered equivalents may be considered if termination material and hermetic sealing requirements are flexible.
