Overview
The 1N4448WS-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 75 V, a forward current rating of 500 mA, and a power dissipation capacity of 200 mW. The device features a reverse recovery time of 4 ns and a maximum reverse current of 2.5 µA at 75 V.
Feature Summary
- Fast switching speed with a 4 ns reverse recovery time
- High conductance for efficient signal processing
- Totally lead-free and fully RoHS compliant construction
- Halogen and antimony free green device
Applications
- General-purpose switching applications
- Automotive electronics requiring specific change control
- Surface mount circuit designs
Procurement Notes
Verify the component against datasheet DS30096 Rev. 18-2 to confirm specifications. Ensure the ordering suffix matches the required tape and reel packing quantity of 3,000 units. Confirm compliance with EU Directive 2002/95/EC (RoHS) and 2015/863/EU (RoHS 3). Validate that the application environment falls within the specified operating temperature range of -55°C to +150°C.
Selection Notes
Select this component for applications requiring high-speed switching in a compact surface mount footprint. Consider the 75 V peak repetitive reverse voltage and 500 mA forward current limits when designing circuits. Evaluate the thermal resistance of 625 °C/W and power dissipation of 200 mW for adequate heat management. Verify compatibility with standard SOD323 pad layouts.
Part Context
This part belongs to the 1N4448 series of fast switching diodes produced by Diodes Incorporated. It is designed as a lead-free alternative to traditional through-hole variants, offering similar electrical performance in a smaller SOD323 package. The device is suitable for automated insertion processes due to its small surface mount form factor.
Replacement Considerations
Consult official documentation for verified substitutes. Cross-reference with other manufacturers' SOD323 fast switching diodes having equivalent 75 V ratings and 4 ns recovery times.
FAQ
