Package
The 1N4148W-E3-18 is a DO-213AA (MELF) package type, a cylindrical glass-encapsulated diode. It's a surface-mount (SMD) variant of the standard 1N4148 switching diode, offering similar electrical characteristics but in a compact, leadless form. The "W" denotes its MELF package, and "E3-18" refers to Vishay's specific part numbering for tape/reel packaging.
