Only One Name Means ProTek’Tion™
500 WATT LOW CAPACITANCE STEERING DIODE/TVS ARRAY
DESCRIPTION
The PSR05 is a low capacitance steering diode TVS array, designed to protect two I/O lines from the effects of Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). The PSR05 exceeds Level 4 IEC 61000-4-2, with a peak
pulse power rating of 500 Watts for an 8/20µs waveshape.
The low capacitance of the steering diode allows the designer to protect high speed data applications. The small
SOT-143 package, with four leads reduces the internal lead inductance for low overshoot voltage during fast front time
transient events, such as ESD and EFT. The PSR05 meet the IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.

FIGURE 1 - USB PROTECTION
Two PSR05s (Unidirectional) in a Common-Mode configuration. Circuit connectivity is as follows:
• Pins 2 and 3 are connected to the datalines
• Pin 1 is connected to ground
• Pin 4 is connected to the databus
CIRCUIT BOARD RECOMMENDATIONS
Circuit board layout is critical for electromagnetic compatibility protection. The following guidelines are recommended:
• The protection device should be placed near the input terminals or connectors, the device will divert the transient current
immediately before it can be coupled into the nearby traces.
• The path length between the TVS device and the protected line should be minimized.
• All conductive loops including power and ground loops should be minimized.
• The transient current return path to ground should be kept as short as possible to reduce parasitic inductance.
• Ground planes should be used whenever possible. For multilayer PCBs, use ground vias.
