40 Watt Peak Power Zener Transient Voltage Suppressors
SOT−23 Dual Common Cathode 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 cathode design protects two separate lines using only one package. These devices are ideal for situations where board space is at a premium.
The SZ/MMBZ27VCL can be used to protect a single wire communication network form EMI and ESD transient surge voltages. The SZ/MMBZ27VCL is recommended by the Society of Automotive Engineers (SAE), February 2000, J2411 “Single Wire Can Network for Vehicle Applications” specification as a solution for transient voltage problems.
