This product is a four-channel common anode transient voltage suppressor for ESD protection. It has four unidirectional configurations and high power output. This product has low leakage and high ESD rating.
The MMQA Quad Common Anode Series consists of preferred devices intended for applications requiring transient overvoltage protection. These quad junction common anode designs protect four separate lines using a single SC-74 package, making them ideal for situations where board space is at a premium. They are suitable for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment.
The document provides comprehensive electrical characteristics for various breakdown voltages ranging from 5.6V to 33V. Key specifications include a minimum peak power of 24W at 1.0ms (unidirectional) and an ESD rating exceeding 16kV per the Human Body Model. The datasheet also includes typical characteristic curves for capacitance, leakage current, and power derating.
