SDT23C712L02

SDT23C712L02 Electrostatic Discharged Protection Devices (ESD) Data Sheet Description Brightking’s SDT23C712L02 component is designed for asymmetrical (12V to -7V) protection in muti-point data transmission standard RS-485 applications. It may be used to protect devices from transient voltages resulting from electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. It features 400W (tp=8/20μs) of power handing capability to accommodate the higher transient voltage levels which may be expected in extended common mode applications.
