1N5986D

Single Zener Diodes Overview

The Microchip Technology 1N5986D is a hermetically sealed, axial-lead glass Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 2.7 V with a tight tolerance of ±1%. The device operates within a junction temperature range of -65°C to +175°C and dissipates up to 0.5 W at 25°C. Key electrical characteristics include a maximum dynamic impedance of 100 Ohms at the test current of 100 mA, a maximum reverse leakage current of 75 µA at 1.0 V, and a typical temperature coefficient of -0.075 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for high reliability
• Tight voltage tolerance of ±1% for precision regulation
• Internal metallurgical bonds for enhanced durability
• Inherently radiation hard

Single Zener Diodes Applications

• Voltage regulation over broad operating currents
• High-reliability military screening applications
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required tolerance level, as the 'D' suffix indicates a 1% tolerance variant. Confirm RoHS compliance status if environmental regulations apply, noting that commercial versions may differ from screened equivalents. Ensure the ordering quantity aligns with factory tape and reel options if available.

Single Zener Diodes Selection Notes

Select this component when a precise 2.7 V reference is required in harsh environments. The DO-35 package supports through-hole mounting. Consider the negative temperature coefficient for thermal compensation needs. Verify power derating requirements if ambient temperatures exceed 25°C or if board-mounted thermal resistance differs from standard FR4 conditions.

Single Zener Diodes Part Context

This device belongs to the 1N5985B-1 thru 1N6031B-1 series of 0.5 watt Zener voltage regulators. The series offers voltages from 2.4 to 200 volts with various tolerance options identified by suffix letters. These components are JEDEC registered and feature flexible axial-lead terminals suitable for general-purpose and specialized electronic circuits.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5986B (5% tolerance) and 1N5986C (2% tolerance). Commercial grade RoHS-compliant versions may be available depending on the manufacturer's current production lines.
