PSR05_12 Datasheet, PDF (1/9 Pages) Protek Devices – 500 WATT LOW CAPACITANCE STEERING DIODE/TVS ARRAY

Only One Name Means ProTek’Tion™
500 WATT low capacitance steering diode/TVS array
PSR05
SOT-143 package
Description
The PSR05 is a low capacitance steering diode TVS array, designed to protect two I/O lines from the effects of Elec-
trostatic 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 require-
ments.
