1N6841U3

Overview

The Microchip Technology 1N6841U3 is a Schottky diode array featuring one pair of common cathodes. It is designed for surface mount applications in a 3-SMD, no-lead package (U3). The device supports a maximum DC reverse voltage of 45 V and an average rectified current of 10 A per diode. Key electrical characteristics include a forward voltage of 750 mV at 10 A and a reverse leakage current of 100 µA at 45 V. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Schottky barrier technology for fast switching performance
• Common cathode configuration for dual-diode integration
• High thermal stability with extended operating temperature range

Applications

• DC-DC converter circuits
• Power supply rectification
• Freewheeling diode applications

Procurement Notes

Verify the specific suffix U3 against the official datasheet to confirm the package type matches the design requirements. Confirm RoHS compliance status as indicated in manufacturer documentation, noting potential variations based on production date or region. Ensure the ordering part number aligns exactly with the required lead time and packaging specifications provided by the authorized distributor.

Selection Notes

Select this component when a low forward voltage drop and high current handling capability are required in a compact surface-mount form factor. The common cathode arrangement simplifies circuit layout for dual-rail or bridge configurations. Verify that the 45 V reverse voltage rating provides sufficient margin for the specific application's peak inverse voltage conditions.

Part Context

The 1N6841 series belongs to Microchip Technology's lineup of discrete semiconductor diodes. These components are engineered for general-purpose rectification and switching tasks. The U3 designation specifies the particular surface-mount package geometry, distinguishing it from through-hole variants within the same electrical family.

Replacement Considerations

Consult the official Microchip datasheet for 1N6840 and 1N6841 to identify electrically equivalent alternatives. Verify pinout compatibility and thermal resistance parameters before substituting with competitor parts.
