BC557 PNP Epitaxial Silicon Transistor 45V 100mA TO-92 is available from Makers Electronics, Microohm, UGE, and Future Electronics. Compare the offers above to find the best price.
How is the BC557 different from the BC558?
Both are general-purpose PNP transistors in TO-92 with 100mA continuous collector current. The BC557 listing shows a DC current gain of up to 300 and emitter-base voltage of 6V, while the BC558 listing shows a gain of up to 800 and 5V. The BC557 is rated at 45V collector-emitter, while the BC558 is rated at 30V.
Is the pin order the same as the BC558?
Both are listed in TO-92 with the same collector, base and emitter order. Because TO-92 pin order depends on how the package is viewed, confirm the pinout in the datasheet before wiring a circuit.
