MMBZ15VDLT1, MMBZ27VCLT1
Preferred Devices
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 MMBZ27VCLT1 can be used to protect a single wire communication network form EMI and ESD transient surge voltages. T h e M M B Z 2 7 V C LT 1 i s r e c o m m e n d e d b y t h e Society of Automotive Engineers (SAE), February 2000, J2411 "Single Wire Can Network for Vehicle Applications" specification as a solution for transient voltage problems.

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.
