1N5314 TR PBFREE

Overview

The Central Semiconductor 1N5314 TR PBFREE is a silicon field effect current regulator diode designed for stable current control. It features a nominal regulating current of 4.70 mA and supports a power dissipation of 600 mW. The device operates within a broad voltage range, specified as 100 PoV (Point of Voltage), ensuring consistent performance across varying circuit conditions. Packaged in an axial leaded configuration suitable for through-hole mounting, it offers reliable operation with low noise characteristics typical of FET-based regulation.

Feature Summary

• Silicon field effect technology for precise current regulation
• Stable performance over a wide operating voltage range
• Low noise operation suitable for sensitive circuits

Applications

• Constant current sources for LED driving
• Biasing circuits for transistors and active components
• Current limiting protection in electronic systems

Procurement Notes

Verify the specific suffix 'TR PBFREE' to confirm reel packaging and lead-free compliance. Ensure the axial package type matches the target PCB footprint requirements. Cross-reference the 4.70 mA nominal current against circuit design specifications to confirm adequate headroom for load variations.

Selection Notes

Select this component when a fixed current source is required without complex feedback loops. The 600 mW power rating allows for moderate voltage drops across the device. Consider the axial package constraints for board layout compared to surface-mount alternatives if space is limited.

Part Context

This part belongs to the 1N53xx series of current regulator diodes manufactured by Central Semiconductor. These devices utilize junction field effect transistor (JFET) principles to maintain constant current. The series provides a cost-effective solution for applications requiring simple, robust current limiting or biasing functions.

Replacement Considerations

Equivalent parts include the 1N5314 from other manufacturers such as Microchip Technology or Compensated Devices Incorporated. Verify that substitute components match the 4.70 mA nominal current and 600 mW power dissipation ratings.
