1N4148 Small Signal Fast Switching Diodes

Vishay Semiconductors 1N4148 Small Signal Fast Switching Diodes are silicon epitaxial planar diodes with a single circuit configuration. These diodes feature 75V reverse voltage, 100V repetitive peak reverse voltage, and 2A forward surge current. The 1N4148W and 1N4148W-G fast switching diodes are AEC-Q101 qualified and comply with Moisture Sensitivity Level 1 (MSL 1). These diodes are ideal for fast switching applications.
