Introduction
The MJE13005 is a high-voltage, high-speed NPN power transistor commonly used in switching applications and power supplies. Designed for efficient operation in high-voltage circuits, it supports a maximum collector-emitter voltage (Vce) of 400V and can handle a collector current (Ic) up to 4A. With its robust construction and fast switching characteristics, the MJE13005 is widely used in SMPS (Switched Mode Power Supplies), lighting circuits, and inverters. It features a TO-220 package, which provides efficient heat dissipation. Its durability and versatility make it a popular choice in applications requiring reliable performance under demanding electrical conditions.
