3A SCHOTTKY BARRIER RECTIFIER DIODE SCHOTTKY DIODES IN DIE FORM FOR HYBRID CIRCUITS USM SR220 FEATURES Extremely low forward voltage VF. Low storred charge due to majority carrier conduction. Low power loss, high efficiency APPLICATIONS In DIE form, this device is an excellent selection for many chip and wire HYBRID CIRCUITS PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE The USM SR220 series of Schottky diode rectifiers, are produced as bare die, chip form only. Low forward voltage drops are obtained through optimization of the Schottky Barrier for a large area metal-to-silicon power diode. State-of-the-art geometry features chrome barrier metal, epitaxial construction with oxide passivation and metal overlap contact. TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-THIN FILM MANUFACTURING All thin film microwave products are manufactured using advanced semiconductors and 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 technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition of a wide range of resistive films with sheet resistance films from 1W/sq to 10,000W/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications.
