PNP/NPN Epitaxial Planar Silicon Transistors
High-Current Driver Applications
· Voltage regulators, relay drivers, lamp drivers,
· Adoption of FBET, MBIT processes.
· Low collector-to-emitter saturation voltage.
· Large current capacity and wide ASO.
· Fast switching speed.
· Very small size making it easy to provide high-
density, small-sized hybrid IC’s.
