FM4007-M-Q1-H

Single Diodes Overview

The FM4007-M-Q1-H is a general-purpose silicon rectifier diode manufactured by Formosa Microsemi Co., Ltd. It features a single-phase, one-element configuration housed in an SOD-123 surface-mount package. The device supports a maximum repetitive peak reverse voltage of 1000V and an average forward rectified current of 1A. It exhibits a low reverse leakage current of 5µA at 1000V and operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Utilizes retardant epoxy molding compound for surface-mounted applications
• Designed for low leakage current performance
• RoHS compliant and lead-free construction

Single Diodes Applications

• General purpose rectification circuits
• Surface-mounted power supply designs
• High-voltage blocking applications

Single Diodes Procurement Notes

Verify the specific suffix Q1 against official Formosa Microsemi documentation to confirm if it denotes a specific tape-and-reel quantity or packaging variant distinct from standard bulk units. Ensure the component matches the SOD-123 footprint requirements for your PCB layout. Confirm RoHS compliance status directly with the manufacturer's latest datasheet revision to meet regulatory standards for your target market.

Single Diodes Selection Notes

Select this component when a high-voltage (1000V) rating is required in a compact SOD-123 surface-mount package. It is suitable for applications demanding low reverse leakage and wide operating temperature ranges up to 150°C. Consider the 1A current limit and ensure thermal management aligns with the expected forward current conditions in the final design.

Single Diodes Part Context

This part belongs to the FM4007 series of general-purpose rectifiers from Formosa Microsemi. The series typically includes variants such as FM4007-M and FM4007-S-H, which share similar electrical characteristics but may differ in packaging or specific manufacturing revisions. The Q1 suffix likely indicates a specific ordering or packaging code rather than a change in fundamental electrical function.

Single Diodes Replacement Considerations

Direct substitutes include other 1A, 1000V silicon rectifiers in SOD-123 packages, such as the 1N4007 equivalent in surface mount form factors. Verify pinout compatibility and thermal resistance values before substitution.
