DN1509 Datasheet | Supertex

.. DN1509 N-Channel Depletion-Mode Vertical DMOS FET Features - - - - - - High input impedance Low input capacitance Fast switching speeds Low ON-resistance Free from secondary breakdown Low input and output leakages General Description The Supertex DN1509 is suitable for high voltage transient protection for LDO in automobile applications during “load dump” conditions. This low threshold, depletion-mode (normally-on) transistor utilizes an advanced vertical DMOS structure and Supertex’s well-proven silicon-gate manufacturing process. This bination produces a device with the power handling capabilities of bipolar transistors and with the high input impedance and...
