It clamps transients at a 7.5V minimum breakdown voltage, with a 7V max reverse standoff — meaning it will not conduct appreciably below 7V, making it a fit for protecting 5V or 3.3V power rails or low-speed I/O lines where the signal swing stays under 7V. ## Peak pulse rating and capacitance — where it fits Rated for 200W peak pulse power (8/20 µs waveform) and 8.8A peak pulse current, this diode can handle moderate ESD strikes and short-duration surges. The 65 pF capacitance at 1 MHz is high compared to low-cap ESD diodes (1–5 pF), so it loads high-speed data lines — reserve it for power inputs, pushbuttons, or low-frequency signals where the extra capacitance does not degrade edge rates. onsemi lists the ESD5Z7.0T1 as Obsolete. If you have an active BOM line with this order code, you need to either secure a last-time-buy quantity or qualify a replacement. The SOD-523 footprint is common — many Zener ESD diodes from onsemi and other vendors share the same package and pinout, but the 7V standoff and 200W rating narrow the cross. We can source the part against your RFQ and confirm availability at quote time.","metaTitle":"ESD5Z7.0T1 onsemi Zener ESD Diode — Obsolete, SOD-523","metaDescription":"onsemi ESD5Z7.0T1 Zener ESD protection diode, 7V reverse standoff, 200W peak pulse, SOD-523.

No direct replacement is published by onsemi. For a drop-in alternative, look for a Zener ESD diode in SOD-523 with a 7V reverse standoff and 200W peak pulse rating — many vendors offer functionally similar parts. We can help identify a cross and source it against your BOM quantity."},{"question":"What package and mounting does ESD5Z7.0T1 use?","answer":"It comes in an SOD-523 surface-mount package (SC-79 equivalent), supplied on Tape & Reel. The small footprint suits high-density PCBs, but the 0.50 mm pitch demands careful solder-paste stencil design to avoid bridging."},{"question":"What is the capacitance of ESD5Z7.0T1, and does it affect signal integrity?","answer":"The capacitance is 65 pF at 1 MHz. That is high for high-speed interfaces — expect signal degradation on USB 2.0, HDMI, or Ethernet lines. It is better suited for power rails, reset lines, or low-frequency I/O where the extra load does not matter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/ESD5Z7.0T1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/ESD5Z7.0T1 when reusing this data.
