Pre-biased PNP in a 1.0 × 0.6 mm footprint
The BCR 166L3 E6327: The Infineon BCR 166L3 is a PNP pre-biased transistor — the base and emitter-base resistors are integrated on-chip, saving two passive components per switch node. Key ratings: 50 V collector-emitter breakdown, 100 mA continuous collector current, and 250 mW power dissipation. Transition frequency is 160 MHz, so it handles modest-speed switching — think GPIO-driven loads, relay or LED drivers, level shifters, and signal inversion in industrial or consumer control boards.
