1N4486US/TR

Single Zener Diodes Overview

The Microchip Technology 1N4486US/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 75 V and a maximum power dissipation of 1.5 W. It features a standard tolerance of ±5% and operates within a junction temperature range of -65°C to +175°C. The device utilizes a voidless hermetically sealed glass package with an internal metallurgical bond, ensuring robust construction for high-reliability applications.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction using internal metallurgical bonds
• Military qualification per MIL-PRF-19500/406 standards
• Non-sensitive to electrostatic discharge (ESD)
• Inherently radiation hard

Single Zener Diodes Applications

• High-reliability voltage regulation where failure cannot be tolerated
• Broad operating current and temperature range stabilization
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific reliability level required, as the base part number may correspond to commercial grade while JAN, JANTX, JANTXV, and JANS levels are available separately. Confirm RoHS compliance status if applicable, noting that compliant versions are restricted to commercial grades only. Ensure the ordering suffix matches the desired tolerance and packaging configuration.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 75 V Zener reference in a surface mount form factor. Consider the thermal impedance characteristics and derating curves for operation above 25°C ambient temperature. Verify that the 1.5 W steady-state power dissipation rating aligns with the circuit's peak load requirements and thermal management capabilities.

Single Zener Diodes Part Context

This device belongs to the 1N4460US through 1N4496US series of industry-recognized 1.5 watt Zener voltage regulators. The series offers selections from 3.3 to 200 volts with standard 5% tolerance, alongside tighter 1% and 2% options. These components serve as surface mount equivalents to popular JEDEC registered axial-lead series.

Single Zener Diodes Replacement Considerations

Equivalent axial-lead parts include the 1N4486. Commercial grade RoHS-compliant alternatives are designated with the e3 suffix.
