| MMBZ27VAWT1G 40 Watt Peak Power Zener Transient Voltage Suppressors SC-70 Dual Common Anode Zeners for ESD Protection 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.
