3 Description
The ESD501 is a bidirectional ESD protection diode.
The ESD501 is offered in the industry standard 0402
DFN1006) package, and offers an IEC 61000-4-2
protection level of 15kV. The device can clamp
8/20μs surges with peak pulse currents up to 3A in
accordance with the IEC 61000-4-5 standard.
The low capacitance and low leakage current help to
ensure protection against transient events in a variety
of systems and applications. This protection is key for
many applications, such as smaller form factors and
faster data speeds, which are becoming more popular
over time.
