The BC557BTF is a PNP epitaxial silicon transistor from On Semiconductor's BC557 series. It is designed for general-purpose switching and amplifier applications. The device features a maximum collector-emitter voltage (VCEO) of -45V and a maximum collector current of -100mA, with a peak pulse current capability of -200mA. Power dissipation is rated at 500mW with a junction temperature limit of 150°C.
Electrical characteristics include a DC current gain (hFE) of minimum 200 at -2mA collector current, a collector-emitter saturation voltage of 650mV maximum, and a gain bandwidth product of 150MHz typical. The transistor is available in the industry-standard TO-92-3 through-hole package, making it suitable for breadboard prototyping and low-cost designs.
The device is fully compliant with RoHS, Pb-Free, and Halogen-Free requirements, and is rated MSL Level 1 (unlimited) for moisture sensitivity. It is a complement to the NPN BC547/BC548 series, allowing easy implementation in complementary push-pull stages.
