Overview
The Central Semiconductor Corp 1N5303 BK TIN/LEAD is a silicon current regulator diode housed in a hermetically sealed glass DO-35 axial leaded package. It provides a stable regulated current of 1.6 mA with a maximum limiting voltage of 1.65 V. The device operates within an extended temperature range from -65 °C to +200 °C, ensuring reliability in harsh environments. Classified as high-reliability hardware, it features isolated case connections and meets JEDEC-95 standards for the DO-35 form factor.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- High-reliability design suitable for demanding applications
- Stable current regulation across wide temperature ranges
Applications
- Constant current sources for LED driving
- Biasing circuits for semiconductor devices
- Current limiting protection in sensitive electronic systems
Procurement Notes
Verify the specific suffix 'BK TIN/LEAD' against official Central Semiconductor documentation to confirm terminal plating composition and packaging format. Ensure procurement channels source directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability for high-reliability requirements.
Selection Notes
Select this component when a fixed low-current regulation of 1.6 mA is required in a through-hole configuration. The DO-35 glass package offers superior thermal stability compared to plastic alternatives. Confirm that the 1.65 V maximum limiting voltage aligns with the circuit's headroom requirements under all operating conditions.
Part Context
This part belongs to the Central Semiconductor line of discrete current regulator diodes. These components are engineered for applications requiring precise current control without active feedback loops. The DO-35 package is a standard industry form factor for small-signal axial devices, facilitating easy integration into printed circuit boards.
Replacement Considerations
Cross-reference with other manufacturers offering DO-35 packaged current regulator diodes with identical 1.6 mA nominal current and similar voltage characteristics. Verify pinout compatibility and thermal performance metrics before substitution.
