ONSEMI 2SB1201STLE Bipolar Transistor

The 2SB1201/2SD1801 are high-performance bipolar transistors designed for applications such as voltage regulators, relay drivers, lamp drivers, and electrical equipment. Featuring low collector-to-emitter saturation voltage, large current capacitance, wide safe operating area, and fast switching speed, these transistors adopt FBET and MBIT processes for enhanced reliability. Their compact, slim packages facilitate smaller set designs, making them ideal for space-constrained electronic circuits requiring high current gain and efficient switching capabilities.
