PJQA6V2
Transient Voltage Suppressors for ESD Protection
This quad monolithic silicon voltage suppressor is designed for applications requiring transient overvolatge
protection capability. It is intended for use in voltage and ESD sensitive equipment such as computers,
printers, business machines, communication systems, medical equipment, and other applications. Its quad
junction common anode design protects four separate lines using only one package. These devices are ideal
for situations where board space is at a premiun.
