Ordering information Table 3. Ordering information Type number Package PESD1V2Y1BSF Name Description Version DSN0603-2 silicon, leadless ultra small package; 2 terminals; 0.4 mm pitch; 0.6 mm x 0.3 mm x 0.3 mm body SOD962-2 7. Application information The device is designed for the protection of one bidirectional data line from surge pulses and ESD damage. The device is suitable on lines where the signal polarities are both positive and negative with respect to ground. The device uses an advanced clamping structure showing a negative dynamic resistance. This snap-back behavior strongly reduces the clamping voltage to the system behind the ESD protection during an ESD event. Do not connect unlimited DC current sources to the data lines to avoid keeping the ESD protection device in snap-back state after exceeding breakdown voltage (due to an ESD pulse for instance). Due to the very low trigger voltage Vt1, it needs to be ensured that VRWMis not exceeded under normal application conditions. If the device is used in an USB 3.2 environment, place the device between the AC coupling capacitor and the transceiver. Refer to the USB 3.2 specification for maximum working voltages. line to be protected ESD protection diode GND aaa-002737 Fig. 1. Application diagram Circuit board layout and protection device placement Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT) and surge transients. The following guidelines are recommended: 1. 2. 3. 4. 5. 6. 7. 8. PESD1V2Y1BSF_SDS Short data sheet Place the device as close to the input terminal or connector as possible. Minimize the path length between the device and the protected line. Keep parallel signal paths to a minimum. Avoid running protected conductors in parallel with unprotected conductors. Minimize all Printed-Circuit Board (PCB) conductive loops including power and ground loops. Minimize the length of the transient return path to ground. Avoid using shared transient return paths to a common ground point. Use ground planes whenever possible. For multilayer PCBs, use ground vias.
