The BC557 is a PNP epitaxial silicon transistor designed for general-purpose switching and amplifier applications. It features a maximum collector-emitter voltage (VCEO) of -45V and a continuous collector current rating of -100mA, with a peak pulse current capability of -200mA. The device offers a DC current gain (hFE) range of 110 to 800 at Vce=-5V and Ic=-2mA, ensuring flexibility in linear amplification circuits.
Key electrical characteristics include a typical current gain bandwidth product (fT) of 150MHz, making it suitable for low-frequency amplification. The transistor has a maximum power dissipation of 500mW at 25°C ambient temperature, with a junction-to-ambient thermal resistance of 250°C/W. It is rated for a maximum junction temperature of 150°C and can be stored between -65°C and +150°C.
The BC557 is housed in a TO-92-3 through-hole package (TO-226-3, TO-226AA), available with straight or bent lead styles. It is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. This device is the PNP complement to the NPN BC547 transistor and is part of a family that includes higher voltage (BC556) and lower noise (BC559, BC560) variants.
