The 2SK2461, 2SK-2461, K2461, 2461 is a 100V 20A 35W N-Channel Field Effect Transistor TO-220NIS Package MOSFET, Its designed for high speed switching applications. Low On-Resistance RDS(on)1 = 80 mΩ MAX. (@ VGS = 10 V, ID = 10 A).
The BC856 3B is a transistors are designed for general purpose amplifier applications. They are housed in the SC−70/SOT−323 which is designed for low power surface mount applications.
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 IRF840PBF is a 500V 8A 125W TO220AB Package Third generation power MOSFETs from Vishay provide the designer with the best combination of fast switching, low on-resistance and cost-effectiveness.
The 2SC3679, 2SC-3679, 3679 is a 900V 5A 100W Silicon NPN Triple Diffused Planar High Voltage Switching Transistor TO-218 Package, Manufactured By SANKEN Semiconductor.
