SRDA3.3-4
Low Capacitance Surface
Mount TVS for High-Speed
Data Interfaces
The SRDA3.3−4 transient voltage suppressor is designed to protect
equipment attached to high speed communication lines from ESD and
lightning.
Features
• Protects 4 I/O Lines
• Low Working Voltage: 3.3 V
• Low Clamping Voltage
• Low Capacitance (<15 pF) for High Speed Interfaces
• Peak Power − 500 W 8x20 ms
• Transient Protection for High Speed Lines to:
IEC61000−4−2 (ESD) ±15 kV (air), ±8 kV (contact)
IEC61000−4−4 (EFT) 40 A
IEC61000−4−5 (Lightning) 25 A
• UL Flammability Rating of 94 V−0
• This is a Pb−Free Device
Typical Applications
