General Description
The LN100 is a 1200V cascoded N-channel MOSFET
with an integrated high value high voltage resistor divider.
Multiple devices can be used in series for voltages
greater than 1200V. A resistor divider ratio of 1000:1 is
provided. High value resistors are used to minimize power
consumption.
The maximum Gate-to-Source threshold voltage is 1.6V.
This allows the Gate to be controlled by low voltage
circuitry. The LN100 can be used as a high voltage low
power pulser. It can also be used in a high voltage low
current amplifier application where it is used to charge and
discharge a small capacitive load.

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.
