1N5309

Overview

The Microchip Technology 1N5309 is a current regulator diode designed for stable current control in electronic circuits. It features a maximum voltage rating of 100V and regulates current at a maximum value of 3.3mA. The device has a maximum power dissipation of 500mW and operates within a junction temperature range of -65°C to 175°C. It utilizes a DO-204AA (DO-7) axial through-hole package. The component is classified under discrete semiconductor products, specifically current regulator diodes.

Feature Summary

Provides constant current regulation with a maximum current of 3.3mA
Supports high-temperature operation up to 175°C junction temperature
Utilizes axial through-hole mounting for reliable circuit integration

Applications

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

Procurement Notes

Verify the specific ordering suffix and manufacturer lot codes when sourcing this component. Confirm RoHS compliance status as indicated by the manufacturer's documentation. Ensure the supplier provides valid traceability records for quality assurance purposes. Cross-reference the datasheet revision to confirm electrical characteristics match design requirements before procurement.

Selection Notes

Select this component when a fixed current source is required within the 3.3mA limit. Ensure the circuit voltage does not exceed the 100V maximum rating. Consider the thermal environment to maintain junction temperatures within the specified -65°C to 175°C range. Verify that the axial leaded package fits the PCB layout constraints.

Part Context

This part belongs to the 1N5309 series of current regulator diodes manufactured by Microchip Technology. It is functionally related to other parts in the 1N5283-1N5314 series, which offer varying current regulation levels. The component serves as a passive solution for current stabilization without requiring complex active circuitry.

Replacement Considerations

Check for direct equivalents within the same series or compatible current regulator diodes from other manufacturers. Verify pinout compatibility and electrical parameter overlaps, particularly the regulated current and maximum voltage ratings, before substituting.
