General Description
Free from secondary breakdown
Low power drive requirement
Ease of paralleling
Excellent thermal stability
Integral source-drain diode
High input impedance and low CISS
ESD gate protection
The LND150 is a high voltage N-channel depletion mode
(normally-on) transistor utilizing Supertex’s lateral DMOS
technology. The gate is ESD protected.
The LND150 is ideal for high voltage applications in the
areas of normally-on switches, precision constant current
sources, voltage ramp generation and amplification.

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.
