The BC817K-40 is a general purpose NPN bipolar junction transistor from Diotec Semiconductor. It features a collector-emitter voltage rating of 45V, a continuous collector current of 500mA, and a peak collector current of 1A. The DC current gain (hFE) is specified in the range of 250 to 630 at 100mA, with a minimum gain of 40 at 500mA. The collector-emitter saturation voltage is typically 0.7V at 500mA.
Designed for surface-mount applications, the device is packaged in a SOT-23 case with low thermal resistance. It can dissipate up to 500mW at a solder point temperature of 115°C. The junction temperature is rated for a maximum of 150°C, and the storage temperature range extends from -55°C to +150°C.
Typical applications include signal processing, switching, and amplification in commercial and industrial grade circuits. The transistor is RoHS compliant and supports lead-free soldering conditions up to 260°C for 10 seconds. Variants with AEC-Q101 qualification are available (suffix -Q or -AQ).
