SMD Codebook serves as a reference for Surface Mount Device semiconductor devices. Contains codes beginning with '0' and '1'. Includes device equivalents and connections for various components
Surface mount devices (SMDs) are increasingly used in commercial products. SMDs offer improved performance over through-hole components. More than 50% of active semiconductor components are SMDs
Zener diode allows current flow backwards when reaching specific reverse voltage. Named after Clarence Zener, who first described it in 1934. Breakdown voltage varies from 1.2 V to 200 V. Heavy doping creates thin depletion region with high electric field
P-n junction combines p-type and n-type semiconductors in a single crystal. N-type contains electrons, p-type contains electron holes. Creates depletion region near junction where electrons fill holes
Computers were first used for calculations by ancient people with abacus. Antikythera mechanism was earliest known mechanical analog computer. Charles Babbage invented first programmable computer in 1822. ENIAC was first electronic programmable computer built in US in 1945
Industry accounts for 30.1% of Japan's GDP (2017). Manufacturing output ranks third highest globally. Industry heavily depends on imported raw materials and fuels
