Multicomp Pro MJE3055T NPN Power Transistor TO-220, 60V 10A

The Multicomp Pro MJE3055T is a robust silicon NPN complementary power transistor engineered for dependable performance in general-purpose amplification and switching circuits. Its 60V collector-emitter voltage rating and continuous 10A collector current capacity make it a versatile and reliable choice for a wide array of electronic designs, from power supplies to motor drivers.

Designed for through-hole mounting in the industry-standard TO-220 package, it offers excellent thermal characteristics and ease of installation on printed circuit boards (PCBs). The device features a minimum DC current gain (hFE) of 20 at 4A, ensuring stable operation in linear applications, while a low collector-emitter saturation voltage (Vce(sat)) of 1.1V maximum at the same current minimises power loss in switching roles.

With a substantial power dissipation rating of 75W and a high maximum operating temperature of 150°C, this transistor is built to handle demanding conditions, making it well-suited for industrial environments. Its 2MHz transition frequency provides adequate speed for many audio and medium-speed switching functions.
