Mute
Eletrônica Aplicada
Assim como outros componentes, o diodo também pode apresentar fuga. Isso acontece quando há uma deterioração interna no semicondutor — uma ou mais regiões do cristal são danificadas, e o diodo deixa de bloquear a corrente como deveria. 📏 Esse teste de fuga é tão importante quanto o teste de junção (aquele que dá 0,7V no multímetro). Você pode testar de várias formas, com multímetro, resistor, ou fonte simples — 🔌 Mas na minha opinião, a forma mais eficaz é com a fonte de bancada.
