Diodo de supresión de voltaje transitorio TVS

Diodo de supresión de voltaje transitorio TVS

I. introducción al título de la prueba TVS

Diodo de supresión de voltaje transitorio, conocido como TVS. Cuando los polos de TVS se ven afectados por El impacto transitorio inverso de alta energía, puede convertir su alta impedancia entre los polos en Baja impedancia a 1012 s y absorber hasta varios kilovatios de potencia de sobretensión, de modo que las abrazaderas de voltaje entre los polos se encuentren en UN valor predeterminado, protegiendo efectivamente los componentes de precisión en los circuitos electrónicos de diversos pulsos de sobretensión.

Second, the selection techniques of TVS

1. TVS Vrwm debe ser más del 10% más alto que la tensión de funcionamiento máxima de cc o continua del circuito protegido, la tensión estándar nominal del circuito y la tolerancia " de gama alta". Si El Vrwm seleccionado es demasiado bajo, El dispositivo puede entrar en una avalancha o afectar El funcionamiento normal del circuito debido a una corriente de fuga inversa demasiado grande. Voltaje de conexión en serie, corriente de conexión paralela.

2.TVS Vc debe ser menor que El voltaje dañado del circuito protegido.

3. la potencia de los televisores Ppp debe ser mayor que la potencia de pulso máxima que puede ocurrir en El circuito protegido.

4. TVS Ipp debe ser mayor que la corriente de sobretensión transitoria del circuito.

5.Para la protección contra rayos del circuito de interfaz de datos, se recomienda elegir UN ESD semiconductor de Baja capacitancia.

6.De acuerdo con El uso de la polaridad de TVS y la estructura del paquete. Selección de circuito de ca de TVS bipolares más razonable; La selección de matrices ESD de semiconductores de protección multilínea es más ventajosa.
