General Description
The Supertex DN2625 is a low threshold depletion-mode
(normally-on) transistor utilizing 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 high breakdown
voltage, high input impedance, low input capacitance, and fast
switching speeds are desired.
The DN2625DK6-G contains two MOSFETs in an 8-lead, dual
pad DFN package. The DN2625K6-G in the 14-lead QFN
package is not recommended for new designs, but may continue
to be purchased for existing designs.
Absolute Maximum Ratings
Parameter Value
Drain-to-source voltage 250V
Drain-to-gate voltage 250V
Gate-to-source voltage ±20V
Operating and storage temperature -55OC to +150OC
Soldering temperature* 300OC
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.
* Distance of 1.6mm from case for 10 seconds.
