Diodo varicap bb809 datasheet

Critical thinking projects for high school students

A corrente reversa pelo diodo cresce abruptamente (conforme mostra a curva da figura 1). Para que se mantenha esta corrente dentro de certos limites sem o risco de destruição do diodo, torna-se necessária a limitação da mesma através de um resistor externo (Rs), que é inserido entre a entrada da tensão (Vin) e o diodo Zener.
