The SMDA03-7 thru SMDA24-7 series of devices is a family of bi-directional, high energy, multi-line EOS (Electrical Over-Stress) arrays available in the industry standard SO-8 package outline. The unique package configuration of the SMDAXX-7 series allows the devices to simultaneously protect up to seven I/O lines, user interface lines, power and accessory ports and Integrated Circuit (IC) voltage rails. Devices are available with working voltage ratings that reflect the most commonly used design values of 3.3, 5.0, 12.0, 15.0 and 24.0 volts. The SMDAXX-7 devices have a much lower idle current (efficiency) than MLVs, have a much tighter clamping ratio (VC/VRWM) for more precise protection and have no inherent “wear-out” mechanism as do MLVs.
Features
• High peak pulse power capability of 300W (8x20μs)
• Flexible configurations for up to 7 lines of protection
• Bi-directional protection
• Broad range of working voltages (3.3V to 24V)
• Low idle / standby current (typically <1μA) for energy efficiency
• Tight clamping ratio (VC/VRWM) typically less than 2 for precise protection
• Industry standard SO-8 package and footprint
• Applications
