2N5384

Overview

The Microchip Technology 2N5384 is a high-voltage silicon planar Zener diode designed for through-hole mounting in the T-18-2 (DO-5) axial leaded package. It provides a nominal Zener voltage of 160 V with a tight tolerance of ±5%. The device is rated for a maximum power dissipation of 5 W and operates within an extended temperature range from -65°C to +150°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 500 nA at the rated voltage and a Zener impedance of 350 Ohms measured at a test current of 8 mA.

Feature Summary

• High-voltage regulation capability with a nominal breakdown voltage of 160 V
• Robust thermal performance supporting up to 5 W power dissipation
• Extended operational reliability across a wide temperature spectrum from -65°C to +150°C
• Low leakage current characteristics ensuring stable circuit behavior

Applications

• High-voltage power supply regulation circuits
• Overvoltage protection stages in industrial equipment
• Reference voltage generation in precision measurement instruments
• Surge suppression in high-voltage DC transmission systems

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and specific manufacturing lot dates, as legacy high-voltage components may have varying environmental certifications. Ensure packaging integrity matches the required reel or cut tape specifications for your assembly process.

Selection Notes

Select this component when a stable 160 V reference is required in high-power applications. The 5 W dissipation rating allows for robust operation without excessive heatsinking in many through-hole designs. Consider the 350 Ohm impedance if line regulation accuracy is critical for the specific load conditions.

Part Context

This part belongs to the standard military-grade and commercial high-voltage Zener diode family produced by Microchip Technology. It utilizes silicon planar technology for improved reliability compared to older alloy junction devices. The DO-5 package is a traditional axial leaded form factor suitable for manual insertion or standard wave soldering processes.

Replacement Considerations

Direct replacements must match the 160 V Zener voltage, 5 W power rating, and T-18-2 package dimensions. Verify that substitute parts offer comparable leakage current and impedance specifications to maintain circuit stability.
