2N5784 NPN Transistor 65V 3.5A TO–39

From the shop's description

2N5784 NPN Transistor 65V 3.5A TO–39 The 2N5784 is a silicon epitaxial NPN power transistor designed for both switching and linear amplifier applications. Housed in a rugged hermetic TO-39 metal package, it offers excellent reliability and thermal performance, making it suitable for demanding industrial, military, and commercial electronic systems. The device is capable of handling relatively high collector currents while maintaining good gain characteristics across a wide operating range. With its combination of high voltage capability, substantial current handling, and fast switching performance, the 2N5784 is well suited for power drivers, relay control circuits, audio amplifiers, voltage regulators, DC power converters, and other medium-power applications. The hermetically sealed package also provides enhanced environmental protection compared to conventional plastic transistor packages. Features: Silicon epitaxial NPN transistor.
