The S8050 is a low voltage high current small signal NPN transistor, designed for Class B push-pull audio amplifier and general purpose applications. S8050 0.5A/40V NPN Transistor TO-92.
The low level triggers the relay module's power indicator (green) and the 4-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided.
The HIP4081A is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The HIP4081A can drive every possible switch combination except those which would cause a shoot through condition.
The TIP145, TIP146 and TIP147 are 100V 10A 125W Silicon Epitaxial-Base PNP power transistors in monolithic Darlington configuration, mounted in TO-220A/B Package.
