SD12C Datasheet | SEMTECH

Description The SDxx C TVS diodes are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook puters, and PDA’s. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when pared to MLVs. The SDxx C series TVS diodes are designed to protect sensitive semiconductor ponents from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The SDxx C is in a SOD-323 package and will protect one bidirectional line. They are available with working voltages of 5 - 24 volts. These devices will fit on the same PCB pad area as an 0805 MLV device. They give the designer the flexibility to protect one line in applications where arrays are not practical. Additionally, it may be “sprinkled” around the board in applications where board space is at a premium. They may may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15k V air, 8k V contact discharge).
