Abstract

Una disposicion para proteger un elemento de una descarga electrostatica; se provee un interruptor para inhibir el flujo de energia a traves del elemento en respuesta a la senal de control; en la modalidad ilustrativa, el interruptor es un interruptor de transistor; se coloca un resistor entre una terminal de entrada del transistor y el suministro positivo para mantener el transistor activo durante la operacion normal; se coloca un capacitor entre la terminal de entrada del transistor y la toma de tierra para evitar que el voltaje de entrada del transistor cambie rapido; la constante de tiempo RC se elige para que sea mucho mayor que la constante de tiempo del pulso ESD; por consecuencia, el voltaje de entrada del transistor permanecera sin modificacion alguna cerca de V y el transistor permanecera inactivo durante el evento ESD, evitando que el elemento dirija la corriente de descarga y proporcionando proteccion ESD.
