LL103A

Single Diodes Overview

The Diotec Semiconductor LL103A is a surface-mount small signal Schottky diode housed in a glass MiniMELF (SOD-80C) package. It features a repetitive peak reverse voltage of 40 V and supports a maximum average forward current of 350 mA at 25°C ambient temperature. The device exhibits a low forward voltage drop of less than 0.37 V at 20 mA and less than 0.6 V at 200 mA. Key electrical characteristics include a typical reverse recovery time of 10 ns, a junction capacitance of 50 pF at 0 V bias, and a leakage current below 5 µA at 30 V reverse voltage. It operates within a junction temperature range of -55°C to +125°C.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power handling

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details and compliance status. Confirm that the component meets RoHS, REACH, and Conflict Minerals requirements as stated in the datasheet. Ensure design parameters align with commercial/industrial grade specifications rather than automotive grades, which are not available for this part number.

Single Diodes Selection Notes

Select the LL103A when a compact SMD Schottky barrier rectifier is required for low-voltage, high-speed applications. Its MiniMELF package offers space efficiency while maintaining a 40 V reverse voltage rating. Consider its thermal resistance and power dissipation limits relative to copper pad mounting areas for proper heat management in dense PCB layouts.
