LL4148-GS08

LL4148-GS08 is a Vishay small-signal fast switching diode in a MiniMELF (SOD-80) package — the surface-mount glass-MELF form of the universal 1N4148 — rated at 100 V reverse voltage and 150 mA average forward current with a reverse recovery time of 4 ns and AEC-Q101 qualification, for high-speed switching, clamping and signal steering in industrial and automotive-adjacent boards. The GS08 suffix is the tape-and-reel packing code for this device. Selection advice: the choice here is the package, not the diode — the LL4148 die is the standard silicon switching diode, but MiniMELF is a cylindrical glass package that needs its correct land pattern and reflow profile and behaves differently on the line from a flat SOD-123 part; choose it where the design or the qualified assembly process calls for MELF, and choose a flat-package sibling where it does not. The AEC-Q101 qualification is the differentiator worth paying for in automotive-adjacent and long-life industrial designs. Parameters verified against Vishay documentation.
