1N4476 TR TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4476 TR TIN/LEAD is a Zener diode voltage regulator. It belongs to the 1N4460–1N4496 series, which are void-less hermetically sealed glass Zener diodes with a 1.5-watt power rating. The device features triple-layer passivation and internal metallurgical bonds for robust construction. It is qualified per MIL-PRF-19500/406 for high-reliability applications where failure cannot be tolerated.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass package construction
• Internal Category 1 metallurgical bonds
• Triple-layer passivation for extreme robustness

Single Zener Diodes Applications

• High-reliability military applications
• Aerospace systems requiring zero-failure tolerance
• Critical voltage regulation circuits

Single Zener Diodes Procurement Notes

Verify the specific revision suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and qualification levels. Ensure the tin/lead termination matches the assembly requirements. Confirm availability of the reel packaging variant if specified in the order.

Single Zener Diodes Selection Notes

Select this component when a 1.5-watt Zener regulator requires hermetic sealing and MIL-PRF-19500/406 qualification. Consider the available tolerance options ranging from standard 5% to tighter 1% or 2% variants depending on circuit precision needs.

Single Zener Diodes Part Context

This part is part of the industry-recognized 1N4460 through 1N4496 series produced by Microsemi (now part of Microchip). These regulators are designed for environments demanding high reliability and physical durability through their unique void-less glass encapsulation technology.

Single Zener Diodes Replacement Considerations

Check for direct equivalents within the 1N44xx series that share the same hermetic glass package and 1.5W rating. Verify that any substitute meets the same MIL-PRF-19500/406 qualification standards.
