Overview
The Microchip Technology 1N5307-1 is a current regulator diode designed for stable current control across a wide voltage range. It features a maximum anode-to-cathode voltage of 100V and regulates current at a maximum value of 2.64mA. The device supports a power dissipation of 500mW and operates within a junction temperature range of -65°C to 175°C. Packaged in the DO-7 axial leaded format, it serves as a counterpart to Zener diodes by regulating current rather than voltage.
Feature Summary
- Provides constant current regulation over a broad voltage range
- High source impedance for stable performance
- DO-7 packaging with double-plug internal bond connection
Applications
- Current limiting circuits
- Biasing elements for active components
- Constant current sources for LED or transistor drives
Procurement Notes
Verify the specific suffix '-1' indicates MIL-PRF-19500/463 qualification when sourcing. Confirm package type is DO-7 axial. Check datasheet for tolerance levels which are typically 10% for this series. Ensure environmental compliance requirements match the commercial or military grade version needed.
Selection Notes
Select based on required regulated current (2.64mA) and maximum operating voltage (100V). Consider the 500mW power dissipation limit for thermal management. Choose the '-1' suffix variant if military qualification per MIL-PRF-19500/463 is required for the application environment.
Part Context
This component belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices offer a selection of currents from 0.22 mA to 4.7 mA in standard 10% tolerances. They are JEDEC registered and provide a reliable alternative to Zener diodes for current regulation tasks in similar axial-leaded packages.
Replacement Considerations
Compatible substitutes include other parts from the 1N53xx-1 series with matching current ratings. Verify that any replacement maintains the 100V maximum voltage and 500mW power rating. Ensure the DO-7 package compatibility for direct board replacement.
