Overview
The onsemi MMBZ27VCLT1G is a 40 Watt Peak Power Zener Transient Voltage Suppressor (TVS) diode designed for applications requiring transient overvoltage protection. This dual monolithic silicon zener diode is packaged in a SOT-23 (SC-59, TO-236) case and features a dual common cathode configuration, allowing it to protect two separate lines using only one package. This device is ideal for situations where board space is at a premium and is used in various voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment.
