1N4480USE3

Single Zener Diodes Overview

The Microchip Technology 1N4480USE3 is a surface mount Zener voltage regulator with a nominal breakdown voltage of 43.0 V and a maximum dynamic impedance of 40 Ohms at a test current of 6.0 mA. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5 W of steady-state power. The device utilizes an A (D-5A) MELF package, weighs 193 milligrams, and features void-less hermetically sealed glass construction.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass package with internal metallurgical bonds for robust construction.
• Triple-layer passivation provides inherent radiation hardness and non-sensitivity to electrostatic discharge.
• Surface mount equivalent of popular JEDEC registered series available in commercial and military qualification levels.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status and tolerance level. Ensure the procurement specification matches the required reliability level, as commercial versions differ from military qualifications. Confirm package dimensions and polarity band marking requirements prior to integration.

Single Zener Diodes Selection Notes

Select this component for surface mount designs requiring high-reliability voltage regulation. Consider the 1.5 W power dissipation rating and thermal resistance characteristics when designing heat management solutions. Verify that the 43.0 V nominal voltage aligns with the target circuit requirements and check if tighter tolerances are necessary for the application.
