This combination produces a device with the power handling capabilities of bipolar transistors and with the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and thermally-induced secondary breakdown. Supertex’s vertical DMOS FETs are ideally suited to a wide range of switching and amplifying applications where high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired. - Telecom **Ordering Information Product Summary Part Number Package Option Packing BVDSX/BVDGX RDS(ON) (max) IDSS (min)** ~~ee~~ DN3765K4-G TO-252 (D-PAK) 2000/Reel 650V 8.0Ω 200mA _-G denotes a lead (Pb)-free / RoHS compliant package.
