Overview
The 1N4448HWSQ-7-F is a surface-mount fast switching diode manufactured by Diodes Incorporated. It utilizes an SOD323 package and operates within a temperature range of -55°C to +150°C. Key electrical parameters include a peak repetitive reverse voltage of 80 V, an average rectified output current of 250 mA, and a power dissipation rating of 200 mW. The device features a maximum reverse-recovery time of 4.0 ns and a total capacitance of 3.5 pF.
Feature Summary
- Fast switching speed for general-purpose applications
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free green device
- Small surface-mount SOD323 package
Applications
- General-purpose switching circuits
- Automotive electronics requiring specific change control
- High conductance signal processing
Procurement Notes
Verify the component against official datasheet DS30196 Rev. 15 specifications. Confirm the SOD323 package type and ensure compliance with AEC-Q100/101 standards if automotive qualification is required. Validate that the ordering suffix matches the requested packing quantity and carrier configuration before finalizing procurement.
Selection Notes
Select this component when a small surface-mount footprint is required alongside high-speed switching capabilities. Ensure the design accommodates the 200 mW power dissipation limit at the intended ambient temperature. Verify that the 80 V peak repetitive reverse voltage meets the circuit's blocking requirements.
Part Context
This part belongs to the 1N4448 series of fast switching diodes produced by Diodes Incorporated. It serves as a surface-mount alternative to traditional through-hole variants, offering similar electrical performance in a compact SOD323 package suitable for automated insertion and dense PCB layouts.
Replacement Considerations
Consult the manufacturer for qualified substitutes. Cross-reference with other 1N4448 series components from different manufacturers only after verifying pinout compatibility, package dimensions, and absolute maximum ratings.
