TVS Diode Arrays (SPA®® Diodes)
Lightning Surge Protection- SP4024 Series
SP4024 Series 1.3pF, 7A Discrete TVS Diode
RoHS
Pb GREEN
Description
The SP4024 series integrates low capacitance steering
diodes with one or two zener diodes for unidirectional or
bidirectional protection, respectively, to protect against
ESD and lightning induced surge events. These devices
can safely absorb up to 7A per IEC61000-4-5 (tp=8/20μs)
without performance degradation and a minimum ±30kV
ESD per IEC61000-4-2 International Standard. The low
loading capacitance and high surge capability make it ideal
for protecting telecommunication ports such as xDSL and
other high voltage, high speed legacy interfaces.
