The 145 pF capacitance at 1 MHz is low enough for most general-purpose data interfaces up to a few MHz, though it will load higher-speed differential pairs. ## 120 W peak pulse — surge energy rating for 8/20 µs Rated at 120 W peak pulse power for an 8/20 µs waveform, with a clamping voltage of 10.9 V at 11 A peak pulse current. This energy rating suits protection against ESD strikes or low-energy surge events on I/O lines, but it is not intended for power-line protection — the part explicitly lacks power line protection. ## SOD-523 — footprint for compact PCB layout Housed in the SOD-523 package, also known as SC-79. This surface-mount package suits dense PCB layouts where space is tight.","metaTitle":"ESD5Z2.5T5G onsemi Zener ESD Protection, 2.5 V, 145 pF","metaDescription":"onsemi ESD5Z2.5T5G Zener diode, 2.5 V reverse standoff, 145 pF capacitance, 120 W peak pulse, SOD-523.
