These enhancement-mode (normally-off) power transistors feature a vertical DMOS structure combined with Supertex’s proven silicon gate technology. This design delivers the power-handling strength of bipolar transistors along with the high input impedance and negative temperature coefficient typical of MOSFETs. Free from thermal runaway and secondary breakdown, Supertex Vertical DMOS Power FETs are ideal for various switching and amplification applications requiring high breakdown voltage, fast switching, low input capacitance, and high input impedance.
