Drain-to-Source Voltage Drain-to-Gate Voltage Gate-to-Source Voltage BVDSX BVDGX ± 20V Operating and Storage Temperature -55°C to +150°C Soldering Temperature* * Distance of 1.6 mm from case for 10 seconds. 300°C Advanced DMOS Technology These depletion-mode (normally-on) transistors utilize an advanced vertical DMOS structure and Supertex’s well-proven silicon-gate manufacturing process. This combination produces devices 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, these devices are free from thermal runaway and thermally-induced secondary breakdown.
