The SEC113ZU is a SOT-323 digital transistor made by SINO-IC that meets RoHS (Restriction of Hazardous Substances) standards. It features an N-channel JFET (Junction Field Effect Transistor) design that provides low On-state resistance (Rds). This makes it ideal for linear and switching voltage applications. It has a blocking voltage range from 30V to 160V, and can handle currents up to 500mA. It is a surface mount device (SMD) that is designed to be used in applications such as computers, consumer electronics, automotive, and military/avionics. It is also RoHS compliant, meaning it does not contain any hazardous materials or substances that can be damaging to the environment.
