Overview
The 1N5313 BK PBFREE is a current regulator diode manufactured by Central Semiconductor Corp. It operates in the DO-35 axial leaded package and provides a regulated current of 4.95mA with a maximum power dissipation of 600mW. The device supports a maximum anode-to-cathode voltage of 100V. This component is designed for applications requiring stable current regulation within a broad operating range.
Feature Summary
- Maintains constant current over a wide range of operating voltages and temperatures
- Constructed with double-plug design for enhanced reliability
- Available in hermetically sealed glass package configuration
Applications
- Current limiting circuits
- Biasing networks for transistors and integrated circuits
- Constant current sources for LED drivers
Procurement Notes
Verify that the specific part number matches the required current rating of 4.95mA and the 600mW power dissipation limit. Confirm the DO-35 package style and lead-free compliance status align with assembly requirements. Ensure the supplier provides official datasheets to validate the 100V maximum voltage specification before finalizing procurement.
Selection Notes
Select this component when a fixed current source is needed without complex circuitry. Consider the 4.95mA output and 100V breakdown voltage as primary constraints. Evaluate thermal management needs based on the 600mW power rating. Compare against other series members if different current levels are required.
Part Context
This device belongs to the 1N53xx series of current regulator diodes, which are silicon junction devices designed to regulate current flow. These components function similarly to Zener diodes but maintain constant current rather than constant voltage. The series offers high reliability for industrial and commercial electronics applications.
Replacement Considerations
Cross-reference with 1N5313 variants from other manufacturers such as Microchip Technology or Central Semiconductor's own TR/PBFREE suffixes to ensure pinout and electrical parameter compatibility.
