Overview
The Central Semiconductor Corp 1N5313 BK TIN/LEAD is a silicon field effect current regulator diode designed to maintain constant current over a wide voltage range. It utilizes the DO-35 double plug case for space savings and improved thermal characteristics. The device features a nominal regulator current of 4.30 mA, with a minimum of 3.66 mA and maximum of 4.95 mA at VT=25V. It has a peak operating voltage of 100 V and power dissipation of 600 mW. Dynamic impedance (ZT) is 0.245 MΩ, knee impedance (ZK) is 0.014 MΩ, and limiting voltage (VL) is 2.75 V.
Feature Summary
- Maintains constant current over a wide voltage range
- DO-35 double plug case provides space savings and improved thermal characteristics
- 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
Procurement Notes
Verify the specific ordering suffix required for your application. The datasheet indicates that adding 'TIN/LEAD' requests Tin/Lead plated devices, while 'PBFREE' requests Lead-free plating. Confirm the exact part number string matches your component requirements before procurement to ensure correct plating specifications.
Selection Notes
Select this component when a stable current source is needed across varying voltages. Consider the 100 V peak operating voltage and 600 mW power dissipation limits. Evaluate the dynamic and knee impedance values against circuit sensitivity requirements. Ensure the DO-35 package fits the design constraints.
Part Context
This component belongs to the 1N5283 through 1N5314 series of silicon current limiting diodes manufactured by Central Semiconductor Corp. These devices are specifically engineered as field effect current regulators. The series offers various current options within the same DO-35 package format.
Replacement Considerations
Compatible substitutes include other parts from the 1N5283 through 1N5314 series or equivalent silicon field effect current regulator diodes in the DO-35 package. Verify matching nominal current, voltage ratings, and impedance parameters.
