1N4454-1

Overview

The Microchip Technology 1N4454-1 is a hermetically sealed standard switching diode designed for high-reliability applications. It features a maximum DC reverse voltage of 75 V and an average rectified current of 200 mA at +25°C ambient temperature. The device exhibits a typical reverse recovery time of 4 ns and a forward voltage drop of 1 V at 10 mA. Reverse leakage current is specified at 100 nA when subjected to 50 V. The junction operating temperature range extends from -65°C to +175°C, ensuring stability under extreme thermal conditions.

Feature Summary

• Hermetically sealed construction with metallurgically bonded double plug design for enhanced durability
• Qualified to MIL-PRF-19500/144 standards for military-grade reliability
• Fast switching capability with low reverse recovery time for signal processing

Applications

• Military aerospace electronic systems requiring radiation-hardened or high-reliability components
• High-temperature industrial control circuits
• Precision signal rectification in computer and communication equipment

Procurement Notes

Verify the specific revision level and lot traceability documentation upon order confirmation. Ensure that the procurement channel provides valid certification for MIL-PRF-19500/144 compliance. Confirm that the delivered units match the exact part number designation to avoid substitution errors in critical assemblies.

Selection Notes

Select this component when hermetic sealing and extended temperature operation are mandatory requirements. The DO-35 axial package facilitates through-hole mounting in dense circuit boards. Consider the 75 V reverse voltage rating to ensure adequate margin against transient spikes in the target application environment.

Part Context

This part belongs to the 1N4454 series of small-signal switching diodes manufactured by Microchip Technology. It serves as the military-grade variant within the family, distinguished by its rigorous qualification process and hermetic packaging compared to commercial equivalents.
