The maximum collector dissipation is 500 milliwatts which are also another good feature of this transistor. The maximum amount of current that could flow through the Collector pin is 100mA, hence we cannot connect loads that consume more than 100mA using this transistor. endobj /Nums [6 15 0 R 8 16 0 R] >> /Parent 2 0 R Brief Description on BC557 Transistor. 16 0 obj SMD Equivalent The SMD versions of the BC557 are available as the BC857 (SOT-23), BC857W (SOT-323), BC860 (SOT-23) and BC860W … /Type /Catalog Some are very large, some so small they require a screwdriver. /Pages 2 0 R 2007-03-29T13:43:51-07:00 Introduction to BC557 BC557 is a bipolar junction transistor that falls under the family of PNP transistors. 17 0 obj 9 0 obj The complementary NPN transistor to the BC557 is the BC547.
