These devices are ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading. Each ESD channel consists of a pair of diodes which will steer the ESD current pulse to either the positive (VP) or negative (VN) supply rail. The SWDL will protect against ESD pulses up to +6kV per the IEC61000-4-2 standard.This device is particularly well-suited for systems using high-speed port implementations such as USB2.0, IEEE1394, (Firewire,i.Link), Gigabit Ethernet and corresponding ports in removable storage, digital camcorders, DVD-RW drives and other applications where extremely low loading capacitance with ESD protection are required in a small package footprint. |

| SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION |
| Integrated passive networks are manufactured using advanced thin film technologies including ultra -stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern. |
