1N4454UR

Overview

The Microchip Technology 1N4454UR-1 is a hermetically sealed switching diode designed for high-reliability applications. It features a DO-213AA outline with copper clad steel leads and tin/lead finish. The device supports an operating current of 200mA at +25°C and withstands surge currents up to 4.0A. Key electrical parameters include a maximum reverse voltage of 50V, forward voltage of 1.0V at 10mA, and reverse leakage of 0.1µA at 50V. It exhibits a reverse recovery time of 4ns and junction capacitance of 2.0pF.

Feature Summary

Hermetically sealed glass package construction
Metallurgically bonded double plug design
Copper clad steel lead material

Applications

Military electronic systems
High-reliability computer circuits
Harsh environment signal processing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance with MIL-PRF-19500/144 standards. Ensure that the required qualification level (JAN, JANTX, or JANTXV) matches the project specifications. Confirm lead material and finish requirements prior to procurement to ensure compatibility with assembly processes.

Selection Notes

Select this component when hermetic sealing and metallurgical bonding are required for environmental protection. The DO-213AA outline provides a compact surface-mount footprint suitable for space-constrained designs. Verify thermal resistance limits and derating factors to ensure safe operation within the specified temperature range.

Part Context

This part belongs to the 1N4454 series of switching diodes manufactured by Microchip Technology. It is available in various qualification levels including JAN, JANTX, and JANTXV. Alternative packages such as LL4454, CDLL4454, and MLL4454 are also offered within the same product family.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements may not meet hermetic sealing or military qualification requirements.
