The 2SC2330 - C2330 NPN Epitaxial Silicon Transistor for Color TV Chroma Output. Collector-Emitter Volt (Vceo): 400V, Collector-Base Volt (Vcbo): 400V, Collector Current (Ic): 100mA, hfe: 40-80 @ 20mA.
The 2N5551 TO-92 NPN High Voltage Transistor 160V 0.6A. NPN high-voltage transistor in a TO-92; SOT54 plastic package. PNP complements: 2N5400 and 2N5401.
The DC-DC module based on LM2596 advocate current to 3.0A, but only to 1.8A.However, being introduced module adds a heatsink, using high-power devices. This module can easily reach 4A, 50W.
The 2SA-1266, 2SA1266-Y is 50V 150mA 400mW PNP Bipolar Transistor, 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.
