JAN1N5308-1

Current Regulation - Diodes, Transistors Overview

The JAN1N5308-1 is a military-grade current regulator diode manufactured by Microchip Technology. It belongs to the MIL-PRF-19500/463 qualified series, providing stable current regulation within the 1N5283-1 through 1N5314-1 family. The device operates in a DO-7 axial leaded package with through-hole mounting. It delivers a nominal regulating current of 3.3 mA with standard 10% tolerance. The component supports a maximum voltage of 100 V and dissipates up to 500 mW of power. It functions effectively over an extended temperature range from -65°C to +175°C.

Current Regulation - Diodes, Transistors Feature Summary

• Provides constant current regulation across a broad voltage range as a counterpart to Zener diodes.
• Features high source impedance for effective current limiting applications.
• Utilizes a double-plug internal bond connection within the DO-7 package for enhanced reliability.

Current Regulation - Diodes, Transistors Applications

• Current limiting circuits requiring stable regulation over wide voltage variations.
• Replacement or alternative solutions for Zener-based voltage regulation in similar form factors.
• Military and aerospace electronic systems demanding MIL-PRF-19500/463 qualification.

Current Regulation - Diodes, Transistors Procurement Notes

Verify that the specific order matches the JAN suffix indicating military qualification under MIL-PRF-19500/463. Confirm the package type is DO-7 axial leaded. Ensure the required current tolerance aligns with the standard 10% specification provided in the datasheet. Check for any specific lot traceability requirements mandated by the procurement contract.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is needed instead of a fixed voltage reference. Compare the 3.3 mA rating against circuit load requirements. Consider the 100 V maximum operating voltage to ensure adequate headroom. Evaluate the thermal management needs given the 500 mW power dissipation limit in the DO-7 package.

Current Regulation - Diodes, Transistors Part Context

This part is part of the broader 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. The series offers various current options ranging from 0.22 mA to 4.7 mA. All devices share similar axial-leaded packaging and regulatory characteristics, differing primarily in their specific regulated current values.

Current Regulation - Diodes, Transistors Replacement Considerations

Commercial equivalents include the 1N5308 without the JAN prefix, though they lack military qualification. Parametric substitutes within the same series are 1N5307 (2.7 mA) or 1N5309 (3.3 mA). Verify that any replacement meets the specific MIL-PRF-19500/463 standards if military grade is required.
