3 Description
The ESD501-Q1 is a bidirectional ESD protection
diode. The ESD501-Q1 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.
