## SD05C through SD24C Single Line TVS Diode for ESD Protection in Portable Electronics
## **PROTECTION PRODUCTS**
## Description
The SDxxC 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 SDxxC 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 SDxxC 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.

## Applications Information
## Device Connection Options
The SDxxC TVS diodes are designed to protect one data, I/O, or power supply line. The device is designed to replace multi-layer varistors (MLVs) in portable applications. It is easily implemented on existing 0805 MLV pads and is only slightly larger than 0603 MLV pads. The device is bidirectional and may be used on lines where the signal polarity is above and below ground. The device is symmetrical, so there is no cathode band.
## Circuit Board Layout Recommendations for Suppression of ESD.
Good circuit board layout is critical for the suppression of fast rise-time transients such as ESD. The following guidelines are recommended (Refer to application note SI99-01 for more detailed information):
- Place the TVS near the input terminals or connectors to restrict transient coupling.
- Minimize the path length between the TVS and the protected line.
- The ESD transient return path to ground should be kept as short as possible.
- Place a TVS and decoupling capacitor between power and ground of components that may be vulnerable to electrostatic discharges to the ground plane.
## Device Schematic and Pin Configuration

## Size Comparison to 0805 MLV

**----- Start of picture text -----**
SOD-323 0805 MLV
Note: Nominal dimensions in inches
**----- End of picture text -----**
## Component Placement Comparison
- Minimize all conductive loops including power and ground loops.
- Use multilayer boards when possible.
- Minimize interconnecting line lengths
- Never run critical signals near board edges.
- Fill unused portions of the PCB with ground plane.
## Matte Tin Lead Finish

**----- End of picture text -----**
Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be determined by the requirements of the solder paste. Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint.
