Overview
The Central Semiconductor Corp 1N5307 BK TIN/LEAD is a silicon current regulator diode designed for through-hole mounting in the DO-204AA (DO-7) axial package. It provides a nominal regulating current of 2.64 mA with a maximum power dissipation of 500 mW. The device supports a maximum anode-to-cathode voltage of 100 V and features a low limiting voltage of 2 V. It operates within a junction temperature range of -65°C to +175°C, ensuring stability in demanding thermal environments.
Feature Summary
- Maintains stable current regulation across varying load conditions
- Operates reliably at elevated junction temperatures up to 175°C
- Utilizes robust axial leaded construction for secure PCB integration
Applications
- Constant current sources for LED driving circuits
- Biasing elements for transistor amplifier stages
- Current limiting protection in sensitive electronic loads
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free or tin/lead composition requirements. Confirm availability status as distribution channels may list this component as end-of-life or limited stock. Ensure the DO-7 package dimensions match the target footprint before finalizing procurement orders.
Selection Notes
Select this component when a fixed low-current regulation value near 2.64 mA is required without active feedback loops. Verify that the 100 V reverse voltage rating exceeds the maximum circuit potential. Consider the 500 mW power dissipation limit to ensure adequate thermal management under continuous operation conditions.
Part Context
This part belongs to the standard 1N5307 series of current regulator diodes manufactured by Central Semiconductor. It serves as a passive alternative to active current sources, offering simplicity in circuit design. The DO-7 package is a legacy axial form factor commonly used in industrial and military-grade electronics requiring high reliability.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other manufacturers producing the 1N5307 specification if direct replacement is necessary.
