1N4448WS RRG

Overview

The 1N4448WS RRG is a small signal switching diode manufactured by Taiwan Semiconductor Corporation. It features a maximum DC reverse voltage rating of 100V and a forward current capacity of 150mA (0.15A). The device utilizes the SOD-323F surface mount package. Key electrical characteristics include a reverse recovery time (trr) of 4 nanoseconds, enabling high-frequency switching performance. The component is designed for applications requiring fast signal processing and efficient rectification in compact electronic circuits.

Feature Summary

• High-speed switching capability with a 4ns reverse recovery time
• Compact SOD-323F surface mount packaging for space-constrained designs
• Rated for 100V reverse voltage and 150mA forward current

Applications

• High-frequency signal processing circuits
• General-purpose switching applications
• Fast rectification in low-power electronics

Procurement Notes

Verify the specific suffix 'RRG' against the manufacturer's official datasheet to confirm exact binning or tape-and-reel specifications. Ensure the SOD-323F footprint matches your PCB design constraints. Cross-reference the 4ns trr and 100V Vrrm ratings with your circuit requirements to guarantee compatibility with intended operating conditions.

Selection Notes

Select this component when a standard switching diode requires enhanced speed due to the 4ns reverse recovery characteristic. The SOD-323F package offers a smaller footprint compared to traditional axial leads, making it suitable for modern surface-mount assembly processes. Confirm that the 150mA current rating meets the peak load demands of the target application without exceeding thermal limits.

Part Context

This part belongs to the 1N4448 series of small signal switching diodes. It serves as a surface-mount alternative to through-hole variants, maintaining similar electrical performance while adapting to automated assembly lines. The Taiwan Semiconductor version adheres to industry-standard pinouts and mechanical dimensions for the SOD-323F form factor.

Replacement Considerations

Compatible substitutes include other SOD-323F packaged switching diodes with equivalent 100V reverse voltage and sub-10ns reverse recovery times. Verify pinout compatibility and thermal dissipation capabilities before swapping.
