Overview
The Central Semiconductor Corp 1N5310 BK TIN/LEAD is a silicon current regulator diode housed in a hermetically sealed DO-35 glass package. It provides a stable regulated current of 1.4 mA with a maximum limiting voltage of 1.55 V. The device operates within an extended temperature range from -65 °C to +200 °C, ensuring reliability in harsh environments. Designed for high-reliability applications, it features a single configuration and utilizes tin/lead terminations for through-hole mounting.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Stable current regulation over a broad operating voltage range
- Extended thermal capability up to +200 °C
Applications
- Constant current sources for LED driving
- Biasing circuits for transistors and integrated circuits
- Current limiting protection in sensitive electronic systems
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest documentation to confirm termination material and compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Confirm that the received parts match the specified DO-35 package and electrical characteristics before integration into production.
Selection Notes
Select this component when a fixed current source is required without complex circuitry. The DO-35 package suits through-hole designs requiring hermetic sealing. Verify that the load voltage remains below the 1.55 V limit to maintain regulation. Consider the 1.4 mA output current as the primary design constraint for downstream components.
Part Context
This part belongs to the JEDEC registered 1N53xx series of current regulator diodes produced by Central Semiconductor. These devices serve as alternatives to Zener diodes by regulating current rather than voltage. The series offers various current values, with the 1N5310 specifically providing 1.4 mA regulation in a standard axial leaded format suitable for general-purpose electronics.
Replacement Considerations
Cross-reference with other manufacturers' 1N5310 equivalents such as those from Microsemi or Vishay. Verify that substitute parts meet the same 1.4 mA current tolerance and 1.55 V maximum voltage specifications. Ensure replacement packages are compatible with existing PCB footprints.
