Datasheet DN2450 (Microchip)

DN2450 N-Channel, Depletion-Mode, Vertical DMOS FET Features Description
• High-input impedance This low threshold, depletion-mode, normally-on, tran- • Low-input capacitance sistor utilizes an advanced vertical Diffusion Metal • Fast switching speeds Oxide Semiconductor (DMOS) structure and a well • Low on-resistance proven silicon-gate manufacturing process. This com- • Free from secondary breakdown bination produces a device with the power-handling capabilities of bipolar transistors, plus the high-input • Low input and output leakages impedance and positive-temperature coefficient inher- ent in Metal-Oxide Semiconductor (MOS) devices.
Applications
Characteristic of all MOS structures, this device is free • Normally-on switches from thermal runaway and thermally-induced second- ary breakdown. • Battery operated systems • Voltage to current converters Vertical DMOS Field-Effect Transistors (FETs) are ide- • Constant current sources ally suited to a wide range of switching and amplifying • Current and voltage limiters applications where a very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired.  2015 Microchip Technology Inc.
