The ZXTN25040DFLTA with Diodes Incorporated Bipolar Transistors – BJT NPN 40V HG Tran is a high-performance, rugged, and reliable transistor manufactured by Diodes Incorporated. This NPN transistor has a maximum collector current of 250 mA, a maximum collector-emitter voltage of 40 V, and an HFE between 50-300 depending on current. The ZXTN25040DFLTA is a high gain, low power, and low noise transistor used in many different low power applications such as signal amplification, motor controls, and switch interfaces due to its low saturation voltage (< 0.2 V), fast switch-off times, and high current gain. It is ideal for high-temperature and high-voltage applications and has an operating temperature range of -55°C to 150°C.
