TEMPE, Arizona, 26 de agosto de 2013 /PRNewswire/ -- ProTek Devices presentó hoy una matriz de supresor de tensión momentánea (TVS) de muy baja capacitancia diseñada para proteger aplicaciones de cómputo de los dañinos efectos de las descargas electroestáticas (ESD) y los rápidos transitorios eléctricos (EFT). Dichas aplicaciones de cómputo incluyen Ethernet 10/100/1000 base T, FireWire, dispositivos para comunicación inalámbrica e interfaces de USB.

La matriz TVS es la PLR3311 y cumple con los requisitos estipulados en las normas IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) e IEC 61000-4-5 (sobretensión). En frecuencias de más alta operación o frecuencias más rápidas de pulsos, la pérdida de inserción y la integridad de la señal constituyen grandes preocupaciones en cuanto a protección de circuitos. La PLR3311 está diseñada para eliminar esas preocupaciones. Este dispositivo ofrece una capacitancia muy baja (5pF [típca]) y baja corriente de fuga. Tiene una potencia máxima por pulsos de 40 vatios por línea (tp = 8/20 micro amps) y baja tensión de enclavamiento. La PLR3311 protege una línea bidireccional. El componente viene con separador de voltaje de calificación 3.3. Cumple con RoHS y REACH.

La PLR3311 viene en un paquete moldeado JEDEC DFN-2-0402. Su peso aproximado es de apenas dos miligramos. El paquete incluye revestimiento de estaño puro (templado) sin plomo y temperatura de reflujo en soldadura (estaño puro - Sn, 100) de 260-270 grados centígrados. Su inflamabilidad es de UL 94V-0. La  temperatura de operación y almacenamiento de la PLR3311 es de -55 a 150 grados centígrados.

Precios y disponibilidad
La PLR3311 de ProTek Devices ya está disponible en grandes cantidades. El precio es de $0,07 en cantidades mínimas de 10.000 unidades. Está disponible cinta y carrete de ocho milímetros conforme a la norma EIA-481. Aquí puede descargarse una hoja informativa detallada.
