TEXAS INSTRUMENTS LP395Z/NOPB

The LP395Z/NOPB is a fast monolithic ultra-reliable Power Transistor with complete overload protection. This very high gain transistor has included on the chip, current limiting, power limiting and thermal overload protection, making it difficult to destroy from almost any type of overload. Thermal limiting at the chip level, a feature not available in discrete designs, provides comprehensive protection against overload. Excessive power dissipation or inadequate heat-sinking causes the thermal limiting circuitry to turn-OFF the device preventing excessive die temperature. It offers a significant increase in reliability while simplifying protection circuitry. It is especially attractive as a small incandescent lamp or solenoid driver because of its low drive requirements and blowout-proof design. It is easy to use and only a few precautions need be observed. Excessive collector to emitter voltage can destroy the LP395 as with any transistor.
