General Purpose Surge Protection - SP1250
TVS Diode Arrays (SPA
®
Diodes)
Description
Applications
The SP1250 unidirectional TVS is fabricated in a proprietary
silicon avalanche technology. These diodes provide a high
ESD (electrostatic discharge) protection level for electronic
equipment. The SP1250 TVS can safely absorb repetitive
ESD strikes of ±30 kV (contact and air discharge as defined
in IEC 61000-4-2) without any performance degradation.
Additionally, each TVS can safely dissipate a 50A 8/20μs
surge event as defined in IEC 61000-4-5 2
nd
edition.
