| 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 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 very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired. Applications Normally-on switches Battery operated systems Converters Linear amplifiers Constant current sources Telecom Ordering Information Device DN1509 Package Option TO-243AA (SOT-89) DN1509N8-G Product marking for TO-243AA: BVDSX/BVDGX 90V RDS(ON) (max) 6.0 IDSS (typ) 540mA where DN5A = 2-week alpha date code -G indicates package is RoHS compliant (`Green') Absolute Maximum Ratings Parameter Drain to source voltage Drain to gate voltage Gate to source voltage Operating and storage temperature Soldering temperature 1 Pin Configuration Value BVDSX BVDGX 20V D -55C to +150C +300C G D (Top View) S Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground. Note 1. Distance of 1.6mm from case for 10 seconds.
