TVS Diode Arrays (SPA(R) Diodes) General Purpose Surge Protection - SP1220 SP1220 20A Discrete Unidirectional TVS Diode RoHS Pb GREEN Description 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.
