Diodo de supressão de tensão transitória TVS

Diodo de supressão de tensão transitória TVS

I. apresentação do título de teste TVS

Diodo de supressão de tensão transitória, ou TVS. Quando OS pólos TVS são atingidos por uma alta Energia transitória inversa, eles podem mudar SUA alta impedância entre OS pólos para uma baixa impedância, absorvendo milhares de quilowatts de potência de sobretensão, mantendo OS alicates de tensão entre OS pólos em um valor predeterminado, protegendo efetivamente OS componentes sofisticados da linha eletrônica contra vários impulsos de sobretensão.

Em segundo lugar, as habilidades de seleção do TVS

1. o Vrwm da TVs deve ser superior a 10% da tensão máxima DC ou contínua do circuito protegido, à tensão nominal padrão do circuito e à tolerância " avançada". Se o Vrwm escolhido for muito baixo, o dispositivo pode entrar em uma avalanche ou o circuito pode estar funcionando normalmente devido a uma corrente de vazamento inversa muito alta. A conexão serial é dividida em tensão e a conexão paralela é dividida em corrente.

2. o Vc do 2.TVS deve ser menor que a voltagem danificada do circuito protegido.

3. o Ppp de potência da 3.TVS deve ser maior que o pico de potência de pulso que pode ocorrer no circuito protegido.

4. o Ipp do TVs deve ser maior que a corrente de surto transitória do circuito.

5. recomenda - se que seja utilizada uma ESD de semicondutor de baixa capacitância para protecção contra raios em circuitos de interface de dados.

6. escolha a polaridade e a estrutura de embalagem do TVS com base no uso. O uso de TVS bipolares em circuitos AC é mais razoável; A proteção de várias linhas é mais vantajosa com arrays ESD semicondutores.
