LND150 N-Channel Depletion-Mode DMOS FET Features General Description Free from secondary breakdown The LND150 is a high voltage N-channel depletion mode Low power drive requirement (normally-on) transistor utilizing Supertexs lateral DMOS Ease of paralleling technology. The gate is ESD protected. Excellent thermal stability Integral source-drain diode The LND150 is ideal for high voltage applications in the High input impedance and low C areas of normally-on switches, precision constant current ISS ESD gate protection sources, voltage ramp generation and amplication. Applications Solid state relays Normally-on switches Converters Power supply circuits Constant current sources Input protection circuits Ordering Information R I Package Options DS(ON) DSS BV /BV DSX DGX Device (max) (min) (V) TO-236AB (SOT-23) TO-92 TO-243AA (SOT-89) (K) (mA) LND150 LND150K1-G LND150N3-G LND150N8-G 500 1.0 1.0 -G indicates package is RoHS compliant (Green) Pin Congurations DRAIN Absolute Maximum Ratings SOURCE Parameter Value GATE Drain-to-source BV DSX TO-92 (N3) Drain-to-gate BV DGX Gate-to-source 20V SOURCE SOURCE O O Operating and storage temperature -55 C to +150 C O Soldering temperature* 300 C DRAIN DRAIN Absolute Maximum Ratings are those values beyond which damage to the device SOURCE may occur. Functional operation under these conditions is not implied. Continuous GATE GATE operation of the device at the absolute rating level may affect device reliability. All TO-236AB (SOT-23) (K1) TO-243AA (SOT-89) (N8) voltages are referenced to device ground. * Distance of 1.6mm from case for 10 seconds.
