1N5299-1

Overview

The 1N5299-1 is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 axial package. It provides a regulated current of 1.32 mA with a maximum voltage rating of 100 V and a power dissipation capacity of 475 mW. The device operates within a temperature range of -55°C to +175°C and features a maximum voltage drop of 1.45 V.

Feature Summary

• Provides stable current regulation across a broad voltage range
• Utilizes double-plug internal bond connection for reliability
• Offers high-temperature operation capability up to 175°C

Applications

• Constant current sources for LED biasing
• Current limiting protection circuits
• Biasing elements for transistor stages

Procurement Notes

Verify the specific suffix '-1' indicates qualification per MIL-PRF-19500/463 standards when required. Confirm the manufacturer datasheet for the 1N5283-1 through 1N5314-1 series for precise electrical tolerances and testing conditions before finalizing procurement specifications.

Selection Notes

Select this component when a fixed current source is needed over a wide voltage span. Ensure the circuit voltage does not exceed the 100 V maximum rating. Verify that the 475 mW power dissipation is sufficient for the operating conditions and ambient temperature requirements.

Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. These devices serve as counterparts to Zener diodes, regulating current rather than voltage. The series offers various current values from 0.22 mA to 4.7 mA in standard 10% tolerances.

Replacement Considerations

Check for other parts in the 1N5283-1 to 1N5314-1 series with similar current ratings. Verify pinout compatibility and package dimensions (DO-7) for direct replacement in existing PCB layouts.
