KZ1045-SP

KZ1045-SP is an ultra-low capacitance transient voltage suppressor designed to protect high-speed data interfaces. With a typical capacitance of only 0.2pF, it protects systems sensitive to parasitic effects from overvoltage and overcurrent transient events. The device complies with IEC 61000-4-2 (ESD) standard at Level 4 (±15KV air discharge, ±8KV contact discharge), and meets IEC 61000-4-4 (EFT) (40A, 5/50ns), very fast charged device model ESD, and cable discharge event requirements. The KZ1045-SP comes in an ultra-compact DFN2510 package, with each device protecting four high-speed data lines. Its combination of ultra-low capacitance, ultra-small footprint, and high ESD robustness makes it an ideal choice for high-speed data port and high-frequency line applications. The low clamping voltage of the KZ1045-SP ensures minimal stress on protected ICs.
