The LL4148 with Switching Diode LL-34 RoHS is a small surface-mount switching diode manufactured by Microdiode Electronics. It is designed to provide high-speed switching for low-voltage, space-efficient applications. It has a RoHS-compliant package and is available in a variety of configurations including an 8-pin SOIC (small outline integrated circuit) package, 4 pins with a 6-mO shunt resistance, and a 2-pin SOT (small outline transistor) package. This diode has a reverse breakdown voltage of 50V and a forward voltage drop of just 0.15V, and is optimized for switching up to 60mA. It is suitable for use in automotive, industrial, and consumer electronics, and is especially suited to applications requiring high reliability, such as those involving communications and data processing.
