| SEMICONWELL - SWDN004-1/2A - ESD PROTECTION DIODE NETWORK ESD protection +8 kV contact, +15 kV air ESD protection per channel (IEC61000-4-2 standard) +15 kV of ESD protection per channel (HBM) Low loading capacitance, 3 pF typical Miniature SOT and TSSOP package Low leakage current ideal for battery-powered devices Consumer electronic products Cellular phones Notebook computers Desktop PCs Digital cameras and camcorders, VGA (video) port protection for desktop and portable PCs PDAs The SWDN004 is a diode array designed to provide two channels of ESD protection for electronic components or sub-systems. Each channel consists of a pair of diodes which steers the ESD current pulse either to the positive (V P ) or negative (V N ) supply. The SWDN004 will protect against ESD pulses up to 15 kV Human Body Model, and 8kV contact discharge per International Standard IEC 61000-4-2. This device is particularlywell-suited for a wide range of portable electronics (e.g. cellular phones, PDAs, notebook computers) because of its small package footprint, high ESD protection level and low loading capacitance. It is also suitable for protecting video output lines and I/O ports. |

| 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. |
