15 AMPERE COMPLEMENTARY SILICON POWER TRANSISTORS 60, 120 VOLTS 115, 180 WATTCASE 1–07 TO–204AA (TO–3)

The 2SC945 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.

BC547 is an NPN bi-polar junction transistor.BC547 is mainly used for amplification and switching purposes. It has a maximum current gain of 800. Its equivalent transistors are BC548 and BC549.

Commonly used for general–purpose power amplifier and switching applications. • 10 A Collector Current • Low Leakage Current — ICEO = 0.7 mA @ 60 V • Excellent dc Gain — hFE = 40 Typ @ 3.0 A  • High Current Gain Bandwidth Product — hfe = 3.0 min @ IC = 0.5 A, f = 1.0 MStandard Casing package: CASE 340D–01 TO–218AC
