J500 TO-92 2L

Current Regulation - Diodes, Transistors Overview

The Linear Integrated Systems J500 is a two-lead current regulator diode designed for stable constant-current applications. It utilizes JFET techniques to maintain a regulated current within a ±20% tolerance range across a wide voltage span. The device operates with a maximum peak operating voltage of 50V and functions reliably within a junction temperature range of -55°C to +150°C. Packaged in a TO-92 two-lead plastic configuration, it eliminates the need for separate biasing circuits or complex series circuitry. This component provides excellent temperature stability and high circuit stability against temperature variations, making it suitable for demanding instrumentation environments.

Current Regulation - Diodes, Transistors Feature Summary

• Maintains constant current output without requiring external biasing circuits

Current Regulation - Diodes, Transistors Procurement Notes

Verify that the specific procurement order explicitly specifies the two-lead TO-92 package variant. Confirm that the application design accommodates the standard ±20% forward current tolerance. Ensure the operating voltage remains below the 50V peak limit to prevent device impairment. Cross-reference the manufacturer designation to confirm Linear Integrated Systems sourcing rather than legacy Siliconix stock.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a simple, two-terminal solution is required for current regulation without active feedback loops. The ±20% tolerance defines the precision limits for the target application. Consider the thermal dissipation capabilities relative to the ambient environment. Verify compatibility with existing PCB footprints designed for the TO-92 form factor.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the J500 series of current regulator diodes manufactured by Linear Integrated Systems. The series was originally developed by Siliconix and subsequently acquired or replaced by Linear Integrated Systems. It represents a specialized class of discrete semiconductor devices focused on passive current stabilization using JFET technology.

Current Regulation - Diodes, Transistors Replacement Considerations

Linear Integrated Systems explicitly replaces the discontinued Siliconix J500. Designers should verify pinout compatibility and electrical parameter alignment when transitioning from legacy Siliconix inventory to current Linear Integrated Systems production units.
