Overview
The Central Semiconductor Corp 1N5312 BK TIN/LEAD is a silicon field effect current regulator diode designed to maintain a constant current over a wide voltage range. It utilizes the cost-effective DO-35 double plug case, offering space savings and improved thermal characteristics. The device features a nominal regulator current of 3.90 mA at a test voltage of 25V, with a minimum dynamic impedance of 0.255 MΩ and a maximum knee impedance of 0.017 MΩ. It operates within a junction temperature range of -65°C to +200°C and supports a peak operating voltage of 100V with a power dissipation rating of 600 mW.
Feature Summary
- Maintains constant current regulation across a wide voltage range
- DO-35 package provides space efficiency and enhanced thermal performance
- High reliability with superior lot-to-lot consistency
Applications
- Applications requiring constant current over a wide voltage range
- Critical applications utilizing special selections of IP (regulator current)
Procurement Notes
Verify that the ordering suffix matches the required plating specification. The suffix "TIN/LEAD" indicates Tin/Lead plated devices, while "PBFREE" denotes Lead-free options. Confirm the specific part number against the manufacturer's datasheet to ensure correct electrical parameters and compliance with standard terms and conditions of sale.
Selection Notes
Select this component based on the required nominal regulator current of 3.90 mA. Ensure the application voltage does not exceed the 100V peak operating limit. Consider the DO-35 package for through-hole mounting and verify that the thermal characteristics meet the system requirements for power dissipation up to 600 mW.
Part Context
This device belongs to the 1N5283 through 1N5314 series of silicon current limiting diodes manufactured by Central Semiconductor Corp. The series offers various special selections of regulator current for critical applications. All types in this series share the same DO-35 double plug case construction and general maximum ratings.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Verify compatibility by matching the nominal regulator current, maximum ratings, and package type with existing designs.
