Description
TLP550 is an eight pins IC constructed with a high-emitting diode and a photodiode in. As we already know, the photocoupler contains an infrared-emitting LED and a photocoupler; a current is first applied to the Optocoupler, which makes the infrared LED emit a light proportional to the current. When the light hits the photosensitive device, it switches on and starts to conduct a current as any ordinary transistor might. Its isolation voltage is 2500VRMS its switching speed is 0.5 microseconds.
