The 2SK3562, 2SK-3562, K3562, 3562 is a Silicon N-Channel Field Effect Transistor. This is an N-Channel MOSFET type of field effect transistor (FET) that is TO-220F Package as the conducting channel to control the flow of current.
These epitaxial planar transistors are mounted in the TO-126 plastic package. The PNP types are the BD136 and BD140, and the complementary NPN types are the BD135 and BD139.
The HA17339A is comparators designed for use in power or control systems. Its operate from a single power-supply voltage over a wide range of voltages, and feature a reduced power-supply current since the power-supply voltage is determined independently.
