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.

LN100
High Voltage, Low Current Digital Pulser
In Figure 3, the six LN100’s are used as the main output
stage for a 3000V low frequency digital pulser. The first three
LN100s are used to charge the load up to 3000V. The next
three LN100s are used to discharge the load back to ground.
The integrated resistors in each of the LN100 allows the
3000V to be divided into thirds. Each LN100 will only need
to hold off 1000V.
