1N4460US/TR

Single Zener Diodes Overview

The Microchip Technology 1N4460US/TR is a surface mount Zener voltage regulator diode with a nominal breakdown voltage of 6.2 V and a standard tolerance of ±5%. It features a 1.5 W steady-state power dissipation rating at 25°C ambient temperature, utilizing a voidless hermetically sealed glass MELF package (D-5A). The device operates within a junction temperature range of -65°C to +175°C and includes internal metallurgical bonds.

Single Zener Diodes Feature Summary

• Hermetically sealed construction using void-less hard glass with tungsten slugs for robust environmental protection.
• Military qualification available per MIL-PRF-19500/406 across JAN, JANTX, JANTXV, and JANS reliability levels.
• Internal Category 1 metallurgical bonds ensure structural integrity and long-term reliability.
• Inherently radiation hard and non-sensitive to electrostatic discharge.

Single Zener Diodes Applications

• High-reliability applications where circuit failure cannot be tolerated.
• Voltage regulation over broad operating current and temperature ranges.
• Radiation-hardened electronic systems.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the required reliability level and RoHS compliance status. Commercial grade versions offer RoHS compliant matte/tin terminations, while military grades utilize tin/lead terminals. Confirm tape and reel packaging specifications against EIA-481-B standards if automated assembly is required.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 6.2 V reference in a compact surface mount form factor. Ensure the thermal management strategy accommodates the 1.5 W power dissipation limit and the specified thermal impedance characteristics. Verify that the application environment aligns with the -65°C to +175°C operating temperature range.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5 Watt Zener diodes. The series provides industry-standard voltage selections from 3.3 V to 200 V with various tolerance options. These devices serve as surface mount equivalents to traditional axial-lead JEDEC registered series, offering enhanced mechanical robustness.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts within the 1N4460US–1N4496US family or equivalent commercial-grade Zener diodes in D-5A packages. Verify that substitute components match the 6.2 V nominal voltage, 1.5 W power rating, and hermetic sealing requirements.
