Manufacturer: Nexperia USA Inc.

Categories: Single Bipolar Transistors

Quality Control: Learn More

Nexperia BC817-40W-MIX is an NPN bipolar junction transistor (BJT) designed for surface mount applications. This component features a 45V collector-emitter breakdown voltage and a maximum collector current of 500mA. The DC current gain (hFE) is specified at a minimum of 250 at 100mA collector current and 1V Vce. With a transition frequency of 100MHz and a maximum power dissipation of 200mW, it is suitable for general-purpose amplification and switching circuits. The device operates across a temperature range of -55°C to 150°C (TJ). Qualified to AEC-Q101 and meeting Automotive grade standards, it is packaged in a SOT-323 (SC-70) case, supplied on tape and reel. This transistor is commonly utilized in automotive electronics and general industrial control systems.
