LL4448 L1G

Single Diodes Overview

The LL4448 L1G is a standard switching diode manufactured by Taiwan Semiconductor Corporation in the Mini MELF (DO-213AC) surface-mount package. It features a peak reverse voltage of 75 V and a maximum average forward current of 150 mA. Key electrical characteristics include a fast recovery time of 4 ns, a forward voltage of 1 V at 100 mA, and a low reverse leakage current of 5 μA at 75 V. The device supports a surge current of 2 A and operates within a temperature range of -65°C to 175°C.

Single Diodes Feature Summary

• Fast switching capability with 4 ns recovery time for high-speed signal processing
• Compact Mini MELF surface-mount design for space-constrained PCB layouts
• Wide operating junction temperature range up to 175°C for thermal robustness

Single Diodes Applications

• High-speed digital logic circuits
• Clamping and protection in RF applications
• General-purpose rectification in consumer electronics

Single Diodes Procurement Notes

Verify the specific manufacturer suffix (L1G) ensures compatibility with Taiwan Semiconductor specifications. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the Mini MELF footprint matches your board design constraints before ordering.

Single Diodes Selection Notes

Select this component when a small form factor is required alongside fast switching speeds. The 75 V rating suits low-voltage DC circuits. Compare against similar SOD-80 devices if higher current or voltage ratings are needed for the specific application environment.

Single Diodes Part Context

This part belongs to the general-purpose switching diode category. It serves as a compact alternative to axial-lead diodes like the 1N4148, offering improved automation assembly capabilities through its surface-mount MELF package while maintaining comparable electrical performance for standard signal applications.

Single Diodes Replacement Considerations

Direct substitutes include the LL4448 from other manufacturers such as Diotec Semiconductor, provided the pinout and electrical parameters match exactly. Verify package dimensions for DO-213AC compatibility.
