| MA3075WALT1 Preferred Device Zener Transient Voltage Suppressor SOT-23 Dual Common Anode Zeners for ESD Protection http://onsemi.com These dual monolithic silicon zener diodes are designed for applications requiring transient overvoltage protection capability. They are intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, medical equipment and other applications. Their dual junction common anode design protects two separate lines using only one package. These devices are ideal for situations where board space is at a premium. Features 1 3 2 PIN 1. CATHODE 2.

ORDERING INFORMATION Device MA3075WALT1 MA3075WALT1G Package SOT-23 SOT-23 (Pb-Free) Shipping 3000/Tape & Reel 3000/Tape & Reel Maximum ratings are those values beyond which device damage can occur. 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 100 ms pulse width 2. Mounted on FR-5 Board = 1.0 X 0.75 X 0.062 in. For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. Preferred devices are recommended choices for future use and best overall value.
