1N6642UE3

Overview

The Microchip Technology 1N6642UE3 is a small signal switching diode designed for surface mount applications. It features a D-5D package and supports a peak reverse voltage of 100 V with a maximum forward current of 100 mA. The device exhibits a fast recovery time of 20 ns and a low reverse leakage current of 25 nA. Operating temperatures range from -65°C to +175°C, ensuring reliability in demanding environments.

Feature Summary

• Surface mount construction in a compact D-5D package
• Fast recovery characteristics suitable for high-frequency switching
• Extended temperature operation up to 175°C

Applications

• Signal or computer diode circuits
• General purpose switching applications
• High frequency rectification tasks

Procurement Notes

Verify the specific suffix 'UE3' confirms lead-free compliance and RoHS status against the official Microchip datasheet. Confirm the D-5D package dimensions match your PCB footprint requirements. Ensure the 100V peak reverse voltage rating exceeds your circuit's maximum transient voltages. Check availability through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a surface mount switching diode with extended high-temperature capability is required. The 100V rating provides headroom for moderate voltage signals. Compare the 20ns recovery time against faster alternatives if ultra-high speed is critical. Verify that the 100mA forward current meets the load requirements of the target application circuit.

Part Context

This part belongs to the 1N6642 series of switching diodes manufactured by Microchip Technology. It shares functional similarities with other general-purpose fast recovery diodes but is distinguished by its specific surface mount packaging and thermal ratings. The UE3 suffix typically denotes environmental compliance within the manufacturer's product line.

Replacement Considerations

Direct substitutes include other 1N6642 variants such as JANS1N6642 for through-hole needs, though package differences require layout changes. Verify electrical parameters like reverse voltage and recovery time match before substitution.
