Overview
The 1N4448W-7-F is a fast switching surface-mount diode manufactured by Diodes Incorporated. It features a peak repetitive reverse voltage of 75 V and a forward continuous current rating of 500 mA. The device exhibits a reverse recovery time of 4 ns and a total capacitance of 4 pF at 0 V. It operates within a junction temperature range of -55°C to +150°C and dissipates up to 400 mW of power. The component is housed in an SOD123 package with matte tin finish terminals.
Feature Summary
- Fast switching speed suitable for high-frequency applications
- Surface-mount package designed for automated insertion
- High conductance characteristics
- Totally lead-free and fully RoHS compliant
Applications
- General purpose switching circuits
- Automotive electronics requiring specific change control
- High reliability applications qualified to JEDEC standards
Procurement Notes
Verify the ordering suffix matches the required packing quantity, as the standard carrier is tape and reel with 3000 units. Confirm compliance requirements such as AEC-Q qualification if intended for automotive use. Check the manufacturer's website for specific packaging details and quality definitions regarding halogen-free status before finalizing procurement specifications.
Selection Notes
Select this component when a fast switching diode with a 75 V reverse voltage rating is required in a compact SOD123 footprint. Ensure the application current does not exceed the 500 mA continuous forward current limit. Consider the thermal resistance of 315 °C/W for heat dissipation calculations in enclosed environments or high ambient temperatures.
Part Context
This part belongs to the 1N4448W series of fast switching surface-mount diodes from Diodes Incorporated. It serves as a modern replacement for through-hole variants, offering similar electrical performance in a smaller form factor. The series is designed for general-purpose switching tasks where speed and low leakage are critical factors.
Replacement Considerations
The datasheet lists the 1N4448WQ-7-F as a related orderable part number within the same SOD123 package family. Verify specific marking or qualification differences between these variants before substitution.
