The 2SK2837, 2SK-2837, K2837, 2837 is a 500V 20A N Channel Silicon Field Effect Transistor Or MOFET TO-3PN-3 Package. Chopper Regulator, DC−DC Converter and Motor Drive.
The 2SC458 is a 30V 100mA NPN (BJT) manufactured in a plastic TO92 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.
The CD4093BM is consists of four Schmitt-trigger circuits. Each circuit functions as a two-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive- and negative-going signals.
The TIP145, TIP146 and TIP147 are 100V 10A 125W Silicon Epitaxial-Base PNP power transistors in monolithic Darlington configuration, mounted in TO-218 Package.
The 2SK2508, 2SK-2508, K2508, 2508 is a 250V 13A 45W TO-220NIS Package, This is a shortly to be discontinued. For new designs, the following product(s) should be used instead of this product.
