APPLICATIONS
Where transient overvoltage protection in sensitive equipment is required, such as:● Universal Serial Bus ports
● RS-423 interfaces
● RS-485 interfaces
● ISDN equipment
● T1/E1 line cards
● HDSL / ASDL interfaces
FEATURES
● Full diode bridge with integrated clamping protection● Breakdown voltage: VBR = 6 V min.
● Peak pulse power dissipation: PPP = 500 W (8/20 µs)
● Very low capacitance, compatible with high debit data or signal rates.
DESCRIPTION
In order to prevent fast transients from leading to severe damages in a high speed data system, a specific protection has been developed by STMicroelectronics. Besides, this device also keeps the power rails in a safe limit thanks to the integrated Transil diode. Benefits● Provides protection for each line and between the supply voltage and GND: 25 A, 8/20 µs.
● High ESD protection level: up to level 3 per MIL STD 883C-Method 3015-6
● Separated inputs and outputs (so-called 4-point structure) to improve ESD susceptibility.
● Comprehensive package pin-out for immediate implementation.
