The QSBT40 is an innovative high-density array designed to protect the sensitive in/out ports of Transistor-Transistor Logic (TTL) and Complementary Metal-Oxide Semiconductor (CMOS) integrated circuits from over voltages caused by induced electrical transients in accordance with IEC 1000-4-2/4/5.
This SOT363 device is based on Diodes' Application Specific Multi-Chip Circuit (ASMCC) high-density implementation. A total of four data line terminators are mounted in one SOT363 surface mount package, with eight separate diodes arranged in four series-connected pairs. This compact 4-line array approach allows for a more effective and efficient layout distribution compared to traditional multi-line monolithic arrays. In addition, the packaging offers as much as a 10:1 board space reduction ratio compared to other discrete Schottky diodes, with a corresponding reduction in component placement costs.
