SHORT PRODUCT APPLICATION NOTE
Integrated clamp Schottky diode network is a low power and low noise solution for reducing reflections on high speed data lines. Reflection on high speed data lines leads to undershoot and overshoot disturbances which may result in improper system operation. Resistor terminations used in parallel or in series with the outputs, when used to terminate high speed data lines, can increase power consumption, degrade the high level output and lower noise immunity or increase propagation delays. Schottky diode termination is the best overall solution for applications in which power consumption and noise immunity are critical considerations. Clamp Schottky diode networks provide optimized lead inductance and parasitic capacitive effects (see added ground pins), improved forward voltage and crosstalk attributes, and best termination performance characteristics at high data transmission rates.

SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION
Schottky diode 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.

SCHOTTKY DIODES RESISTORS CAPACITORS
Schottky diodes offers basic ESD protection, with low forward voltage and low power dissipation. Diodes are small physically resulting low junction capacitance and low loading capacitance. The bonding pads are 3µm thick, 99.99% electroplated gold with a TiW barrier that withstands 30 min at 400°C in air without loss of adhesion. Silicon nitride dielectric, MNOS capacitors exhibit high stability, low temperature coefficients, low leakage <10nA and high BV>50V.

Delivery for packaged RCD standard products is 6-8 weeks ARO. Certain items may be available from stock. For standard products available from stock, there is a minimum line item order of $250.0. Inventory is periodically updated. For 2500pc or larger orders, all surface mount packaged devices are shipped in tape on reel (T/R). For smaller quantities, it may vary. Samples are available only for customers that have issued firm orders pending qualification of product in a particular application. On line Orders have to be verified, accepted and acknowledged by Semiconwell sales department in writing before, becoming non cancelable binding contracts.

Semiconwell guarantees continuous supply and availability of any of it's standard products provided minimum order quantities are met.
