Description
The SDxx TVS diodes are designed to replace multilayer varistors (MLVs) in portable applications such as cell
phones, notebook computers, and PDA’s. They offer superior electrical characteristics such as lower clamping
voltage and no device degradation when compared to MLVs. The SDxx series TVS diodes are designed to protect
sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage
induced transient events.
The SDxx is in a SOD-323 package and will protect one unidirectional line. They are available with working
voltages of 5 volts (SD05) and 12 volts (SD12). 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 be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8Kv contact
discharge).
