Product Overview:
TN2640K4 N-Channel Enhancement-Mode DMOS FET. The device features fast switching
speeds, low parasitic capacitances and a low gate threshold for ease of driving the FET. It’s D-
Pak package gives designers the flexibility to use the device in a wide range of power switching
and amplifying applications. It has a high breakdown voltage (400V), a low on-resistance (5.0W)
and a low input capacitance (225pF) for fast switching applications. Adding these features into
the D-Pak package increases the power dissipation capability to 2.5W in small footprints
utilizing surface mount technology. It’s low input and output leakage feature improves standby
power dissipation while minimizing signal attenuation.
