The Nexperia BC817-40-QR is a single NPN bipolar junction transistor supplied in a three-pin SOT-23 surface-mount package. Bipolar junction transistors are current-controlled devices in which base current sets a proportionally larger collector current, so they serve as both switches and small-signal amplifiers. Nexperia lists the part as in Production and RoHS compliant, delivered on tape and reel in 3, 000-piece quantities.
Small-signal NPN transistors in SOT-23 are used for load switching, LED and buzzer drive, relay and motor pre-driver stages, and general signal amplification on densely packed boards. Automotive, industrial and consumer OEMs consume this class of device in very high volume, usually via contract manufacturers buying to full reels. Only six attributes are recorded for this product and none of them are electrical, so confirm voltage, current, gain and power dissipation ratings against the Nexperia datasheet.
Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
