Littelfuse SP432x-01WTG TVS Diodes

Littelfuse SP432x-01WTG TVS Diodes provide ultra-low capacitance, bidirectional, and a high level of protection for 1 channel electronic equipment. These TVS diodes feature a typical capacitance of 0.3pF, ensuring excellent signal integrity on electronic interfaces, such as DisplayPort, Thunderbolt, and high-speed USB. The SP432x-01WTG TVS diodes safely absorb repetitive ESD strikes at ±12kV and ±14kV (contact discharge (IEC 61000-4-2) without performance degradation. These Transient Voltage Suppression (TVS) diodes are halogen and lead-free, and are RoHS compliant. Typical applications include cell phones, computing, displayport, thunderbolt, S-ATA, MIPI, and USB 2.0 to 4.0.
