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 combination produces a device with the power handling capabilities of bipolar
transistors and with the high input impedance and positiv...
