The PZTA14 is an NPN Darlington transistor designed for applications that demand extremely high current gain. It features a continuous collector current rating of 1.2 A and a collector-emitter voltage of 30 V. Key characteristics include a high DC current gain (hFE) of at least 20,000 at a collector current of 100 mA and a total power dissipation of 1 W. The device operates across a wide junction temperature range of -55°C to +150°C, ensuring reliability in various conditions. Its high gain and current capabilities make it suitable for driver stages, switching circuits, and general-purpose amplification.
