Datasheet SP1250 (Littelfuse)

TVS Diode Arrays
(SPA ® Diodes) General Purpose Surge Protection - SP1250
RoHS Pb GREEN
SP1250 50A Discrete Unidirectional TVS Diode
Description
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 2nd edition. Note: This package image is for example and reference only. for detail package drawing, please refer to the package section in this datasheet.
