500 WATT ultra low capacitance steering diode/TVS array
Description
The PSR05LC is an ultra 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 provides ESD protection up to 25
kilovolts. The PSR05LC has 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. The PSR05LC meets the IEC 61000-4-2 and IEC 61000-4-4 requirements.

Two PSR05LCs 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 dedicated ground planes.
