Lightning Surge Protection - SP2504N Series

SP2504N Series 2.5V 20A Diode Array

Pinout

RoHS

Pb

GREEN

Description

The SP2504N integrates 4 channels of low capacitance
diodes with an additional zener diode to protect sensitive
I/O pins against lightning induced surge events and
ESD. This robust device can safely absorb up to 20A per
IEC61000-4-5 (t

=8/20μs) without performance degradation

P

and a minimum ±30kV ESD per IEC61000-4-2 international
standard. The low loading capacitance makes the SP2504N
ideal for protecting high-speed signal pins.

Features

• ESD, IEC61000-4-2,
±30kV contact, ±30kV air

• EFT, IEC61000-4-4, 40A
(t

p

=5/50ns)

• Low capacitance of 3.5pF
(TYP) per I/O

• Low leakage current of
1µA (MAX) at 2.5V

• Lightning, IEC61000-4-5,
20A (t

p

=8/20µs)
