NXP USA Inc. BC557-112 is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. This component features a maximum collector-emitter breakdown voltage of 45 V and a continuous collector current capacity of 100 mA. The transistor exhibits a minimum DC current gain (hFE) of 125 at 2 mA and 5 V, with a transition frequency of 100 MHz. Maximum power dissipation is rated at 500 mW. The BC557-112 is housed in a TO-92-3 (TO-226-3, TO-92-3 Formed Leads) package, suitable for through-hole mounting. Typical applications include consumer electronics, industrial control systems, and audio amplification circuits. The collector cutoff current (ICBO) is a maximum of 15 nA, and the Vce saturation voltage is 650 mV at 5 mA collector current and 100 mA collector current. This device operates within a junction temperature range of -55°C to 150°C and is supplied in bulk packaging.
