The DP3139KT with SOT-523 MOSFETs ROHS is a dual-channel N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) developed by Doeshare. It is in a SOT-523 package type, meaning it contains two N-channel MOSFETs in a single housing with a total of five pins. It is commonly used in power management circuits, including LED drivers, battery chargers, and voltage regulators, due to its great heat dissipation and high energy efficiency. The DP3139KT has a high-gain improvement and high-current carrying capacity, making it suitable for high-power applications up to 500mA. It is also electrically protected against surge and reverse-bias damages, enabling high-reliability operations. Additionally, this Doeshare MOSFET is RoHS compliant with lead-free manufacturing standards; it is safe to use, environmentally friendly, and provides reliable and robust performance.
