Low Capacitance ESD Protection -ESDSR05
Description
The ESDSR05 consists of four, low capacitance
steering diodes and a low voltage TVS diode that provide
protection against ESD and lightning surge events. Each
channel or I/O pin can safely absorb up to 25A (tp=8/20
μs) and repetitive ESD strikes above the maximum level
(Level 4) specified in the IEC 61000-4-2 international
standard without performance degradation.
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 .
