1N5284 TR TIN/LEAD

Overview

The 1N5284 is a silicon planar Zener diode manufactured by Central Semiconductor Corp, designed for voltage regulation and reference applications. It features a nominal Zener voltage of 36 V with a power dissipation rating of 500 mW at ambient temperatures up to 75°C. The device utilizes a DO-35 glass passivated axial leaded package, suitable for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a Zener impedance of 19 ohms tested at 5 mA. The component operates within a junction temperature range of -65°C to +200°C and is supplied in bulk packaging.

Feature Summary

• Glass passivated junction for enhanced environmental stability
• Axial leaded construction for reliable through-hole integration
• High thermal stability with extended operating temperature limits

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal processing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm packaging type and compliance status. Ensure the requested variant matches the required voltage tolerance and power derating curves for the intended thermal environment. Cross-reference part numbers with authorized distributors to confirm authenticity and traceability documentation availability prior to purchase.

Selection Notes

Select this component when a stable 36 V reference is required in a standard axial package. Evaluate the 500 mW power rating against expected circuit dissipation to ensure operation within safe thermal limits. Consider the 19 ohm impedance value for noise sensitivity requirements in low-current regulation scenarios.

Part Context

This part belongs to the 1N52xx series of low-power Zener diodes produced by Central Semiconductor. The series offers various voltage options in the DO-35 package, providing a standardized solution for discrete voltage regulation tasks in industrial and consumer electronics where through-hole reliability is prioritized over surface mount density.

Replacement Considerations

Equivalent parts include other manufacturers' 1N5284 variants or 1N7548 equivalents. Verify pinout compatibility and ensure that replacement devices meet or exceed the 500 mW power dissipation and 200°C junction temperature specifications.
