General Description
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.
Applications
Solid state relays
Normally-on switches
Converters
Power supply circuits
Constant current sources
Input protection circuits

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.
