Small-signal PNP for low-level switching and amplification
The 2SB1093-AZ from onsemi is a PNP small-signal bipolar transistor, designed for general-purpose amplification and low-current switching in through-hole designs. As a small-signal device it handles modest collector currents typical of preamp stages, signal routing, and level shifting where a PNP polarity is needed.
Bulk packaging and through-hole fit
the 2SB1093-AZ is intended for through-hole insertion, not surface-mount reflow. The transistor's leads are formed for standard 0.1-inch pitch PCB holes, making it a direct drop-in for legacy designs or breadboard prototyping.
