The BC858BWT1G is a PNP silicon bipolar junction transistor manufactured by onsemi (formerly ON Semiconductor). It is designed for general-purpose amplifier applications and is housed in the SC-70/SOT-323 surface-mount package, which is optimized for low-power applications.
Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 30V, a maximum collector-base voltage (VCBO) of 30V, and a maximum emitter-base voltage (VEBO) of 5V. The continuous collector current is rated at 100mA, with a peak current capability of 130mA (1ms pulse). The transistor provides a minimum DC current gain (hFE) of 220 at IC=-2mA and VCE=-5V, and a typical transition frequency (fT) of 100MHz. The maximum collector-emitter saturation voltage (VCE(sat)) is 650mV at IC=-100mA and IB=-5mA.
Power dissipation is rated at 150mW on an FR-5 board, with a maximum junction-to-ambient thermal resistance of 883°C/W. The device operates over a junction temperature range of -55°C to +150°C. The BC858BWT1G is Pb-Free, Halogen Free/BFR Free, and RoHS compliant, making it suitable for environmentally sensitive applications.
Typical applications include general-purpose amplification, signal switching, and low-power circuit designs. The compact SC-70-3 package (also known as SOT-323) allows for high-density board layouts in portable and space-constrained electronics.
