Diode Arrays Procurement Notes

Verify the specific ordering suffix and manufacturer lot code upon receipt to ensure compliance with defense procurement standards. Confirm that the component matches the JAN1N6642UBD designation exactly, as suffix variations may indicate different packaging or qualification levels. Request full traceability documentation and material certifications from the supplier to validate authenticity and adherence to original manufacturing specifications.

Diode Arrays Selection Notes

Select this component when radiation tolerance and extended temperature ranges are critical requirements. The ceramic package provides superior environmental stability compared to plastic alternatives. Ensure the circuit design accommodates the 75 V reverse voltage limit and 100 mA forward current constraints. Verify that the 5 ns recovery speed meets the system's switching frequency demands without introducing excessive delay.

Diode Arrays Part Context

This part belongs to the JAN series of high-reliability semiconductors produced by Microchip Technology, formerly Microsemi. The JAN prefix indicates compliance with strict military quality standards. It is distinct from commercial variants like the 1N6642 due to enhanced screening processes and radiation hardness verification. The UBD suffix specifically denotes the surface-mount ceramic package configuration.
