The BC817-40LT1 is an NPN silicon bipolar junction transistor designed for general-purpose switching and amplification applications. It features a collector-emitter breakdown voltage (V(BR)CEO) of 45 V minimum and a continuous collector current rating of 500 mA. The DC current gain (hFE) is specified at 250 to 600 when tested at IC=100 mA and VCE=1 V, ensuring consistent performance in linear circuits.
This transistor offers a maximum power dissipation of 225 mW on an FR-5 board and 300 mW on an alumina substrate at 25°C ambient temperature. The junction-to-ambient thermal resistance is 556 °C/W on FR-5 and 417 °C/W on alumina. Electrical characteristics include a collector-emitter saturation voltage of 700 mV max at IC=500 mA and IB=50 mA, and a current-gain bandwidth product (fT) of 100 MHz minimum.
The BC817-40LT1 is housed in a surface-mount SOT-23-3 (TO-236) package, making it suitable for compact PCB designs. It is Pb-free, halogen-free/BFR-free, and RoHS compliant. The device is also available in automotive-grade variants (SBC817-40L) with AEC-Q101 qualification.
