BC817W-QX Description

Short technical summary and product information.

The BC817W-QX is an NPN general-purpose transistor from Nexperia, part of the BC817W-Q series. It is designed for general-purpose switching and amplification applications and is qualified to AEC-Q101 for automotive use.

 

With a maximum collector-emitter voltage (VCEO) of 45V and a maximum collector current (IC) of 500mA, it offers a DC current gain (hFE) ranging from 100 to 600 at VCE=1V, IC=100mA. The transition frequency (ft) is typically 100MHz, and the collector-emitter saturation voltage is 700mV maximum at Ib=50mA, Ic=500mA. Additional ratings include a peak collector current of 1A, collector-base voltage of 50V, and emitter-base voltage of 5V.

 

The transistor is housed in a surface-mount SOT323 (SC-70) package, suitable for compact PCB designs. It has a maximum power dissipation of 200mW on a standard FR4 PCB footprint, and up to 290mW with a 1cm² collector pad. The junction temperature range is up to 150°C, with an ambient temperature range of -65°C to 150°C.

 

The BC817W-QX is listed as RoHS3 compliant, REACH unaffected, and has a moisture sensitivity level of 1 (unlimited). It is recommended for use in automotive and general-purpose electronic circuits.
