DMOS FET
LND150
Features
► Free from secondary breakdown
► Low power drive requirement
► Ease of paralleling
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.
► Excellent thermal stability
► Integral source-drain diode
► High input impedance and low C
► ESD gate protection
ISS
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.
