LND150/LND250 N-Channel Depletion-Mode DMOS FETs Features General Description
• Free from Secondary Breakdown The LND150 and LND250 are high-voltage N-channel • Low-Power Drive Requirement Depletion-mode (normally-on) transistors utilizing lateral DMOS technology. The gate is ESD protected. • Ease of Paralleling • Excellent Thermal Stability The LND150/LND250 are ideal for high-voltage appli- cations, such as normally-on switches, precision • Integral Source-Drain Diode constant-current sources, voltage-ramp generation • High Input Impedance and Low CISS and amplification. • ESD Gate Protection
Applications
• Solid-State Relays • Normally-On Switches • Converters • Power Supply Circuits • Constant-Current Sources • Input Protection Circuits
Package Types 3-lead TO-92 3-lead SOT-23 3-lead SOT-89
