SHORT PRODUCT APPLICATION NOTE
The SWLCDA is a low capacitance transient voltage suppressor (TVS) diode array. It is designed to protect sensitive CMOS ICs from the damaging effects of ESD and lightning. Each device will protect one line in common (line-to-ground) mode or one line pair in metallic (Line-to-line) mode. They are low capacitance (< 15pF) making them suitable for use on high-speed telecom and datacom interfaces without signal degradation.The configuration of the SWLCDA has been optimized f or easy layout on high density boards. The small SOT-143 package minimizes required board space. These devices will handle up to 20 Amps for an 8/20µs lightning impulse. The low inductance construction minimizes voltage overshoot during high current surges.The LCDAxxC-1 may be used to protect ADSL interfaces, multi-protocol serial transceivers, portable electronics, and wireless systems.
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.
