Product Description
Product Overview
The TN2640 is a low-threshold, N-Channel Enhancement-Mode Vertical DMOS FET designed for a wide range of switching and amplifying applications. It features a vertical DMOS structure and a silicon-gate manufacturing process, offering the power handling capabilities of bipolar transistors with the high input impedance and positive temperature coefficient of MOS devices. This device is free from thermal runaway and thermally induced secondary breakdown, making it ideal for logic-level interfaces, solid-state relays, battery-operated systems, photovoltaic drives, analog switches, general-purpose line drivers, and telecommunication switches.
