SMD LED 0402 Red UV light emitting diode PCB DIY Assorted Kit,
- Led chip lamp is made of FPC Circuit Board, LED lamp and silicon sleeve.
- In the semiconductor diode there is a , this electronic device acco the direction of the applied voltage, with one-way current conductivity, in general, a SMD is a P-N junction interface formec by the sintering of p-type and n-type semiconductors.
- When the applied voltage is equal to zero, the diffusion current caused by the difference of carrier concentration between two sides of P-N junction is equal to the drift current induced by self-built electric field
