LL4148 and LL4448 are small signal fast switching diodes. They are silicon epitaxial planar diodes with identical electrical data with 1N4148 and 1N4448 respectively. They are lead (Pb) free and compliant with RoHS 2002/95/EC and WEEE 2002/96/EC. They are ideal for extreme fast switching applications.
The Multicomp 1621882 series comprises high‑speed small‑signal diodes offered in a MiniMELF (SOD80) glass case. They are lead‑free, RoHS‑compliant components suitable for extreme fast‑switching applications.
Key specifications include a 100 V repetitive peak reverse voltage, 300 mA continuous forward current and 500 mW power dissipation. The series is supplied as LL4148 and LL4448 part numbers in tape‑and‑reel packaging (GS18/10k or GS08/2.5k).
