PJSR12
Low Capacitance TVS and Diode Array
This diode array is configured to protect up to two data transmission lines
acting as a line terminator, minimizing overshoot and undershoot conditions
due to bus impedance as well as protect against over-voltage events as
electrostatic discharges. Additionaly the TVS Device offers overvoltage
transient protection between the operating voltage bus and ground plane.
