General Purpose Surge Protection - SP1220
TVS Diode Arrays (SPA® Diodes)
Description
Applications
The SP1220 unidirectional TVS is fabricated in a proprietary
silicon avalanche technology. These diodes provide a high
ESD (electrostatic discharge) protection level for electronic
equipment. The SP1220 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 20A 8/20 surge
event as defined in IEC 61000-4-5 2nd Edition.
Features
• ESD, IEC 61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC 61000-4-4, 40A
(5/50ns)
• Lightning, 20A (8/20μs as
defined in IEC 61000-4-5
2nd Edition)
• AEC-Q101 qualified
• Lead-Free and RoHS-
Compliant
• Moisture Sensitivity Level
(MSL -1)
