LESHAN RADIO COMPANY, LTD. Low Capacitance Q uad Array for ESD Protection General Description This integrated transient voltage suppressor device (TVS) is designed for applications requiring transient overvoltage protection. It is intended for use in sensitive equipment such as computers, printers, business machines, communication systems, medical equipment, and other applications. Its integrated design provides very effective and reliable protection for four separate lines using only one package. These devices are ideal for situations where board space is at a premium.

Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. Non−repetitive current pulse per Figure 1. 2. Only 1 diode under power. For all 4 diodes under power, PD will be 25%. Mounted on FR4 board with min pad.
