The BC858AW-TP is a PNP silicon small-signal bipolar junction transistor manufactured by Micro Commercial Components. It operates with a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 30 V. The device features a DC current gain (hFE) minimum of 125 at 2 mA and 5 V. It has a transition frequency of 100 MHz and a maximum power dissipation of 150 mW. The component is housed in an SOT-323 surface-mount package and supports a junction temperature range from -65°C to 150°C.
Verify the specific suffix AW against the manufacturer's datasheet to confirm the exact hFE binning and electrical tolerances. Ensure the ordering part number matches the required package type and compliance standards. Cross-reference the manufacturer's official documentation for any updates regarding RoHS or REACH status before finalizing procurement specifications.
Select this component when a PNP transistor with a 30V rating and 100mA continuous current capability is required. The SOT-323 package is suitable for high-density PCB layouts. Consider the thermal characteristics and the specific hFE requirements of the application circuit to ensure proper biasing and signal integrity during operation.
This component belongs to the BC858 series of general-purpose PNP transistors. It is functionally similar to other industry-standard small-signal transistors but is specifically packaged in the SOT-323 form factor by MCC. The series is designed for low-power surface mount applications, offering a compact alternative to larger through-hole packages while maintaining reliable performance in standard electronic circuits.
Public confirmed substitute part numbers include NSVBC858AWT1G.
