The 80 pF capacitance at 1 MHz is a constraint for high-speed lines — a lower-capacitance alternative (e.g., 0.5 pF to 5 pF) may be needed for USB 2.0 or Gigabit Ethernet ports. ## Protection window — 5V rail, 18.6V clamp The ESD5Z5.0T1 is a unidirectional Zener diode designed to shunt ESD strikes on a 5V or lower signal or power rail. The reverse standoff voltage is 5V max — the diode does not conduct below that. Breakdown starts at 6.2V min, and the clamp voltage peaks at 18.6V at the rated peak pulse current of 9.4A (8/20µs waveform). That clamp ceiling protects downstream ICs rated for 20V absolute max or higher. Peak pulse power is 174W for an 8/20µs surge — enough for IEC 61000-4-2 level 4 (8 kV contact, 15 kV air) on a typical port. The 80 pF capacitance adds about 2 pF of load per inch of trace at 1 MHz; for sub-100 MHz signals the loading is manageable, but for RF or high-speed differential pairs it will degrade eye margin. ## Package and inventory — SOD-523 on tape The ESD5Z5.0T1 is supplied in a SOD-523 surface-mount package, delivered on Tape & Reel. The SOD-523 footprint is 1.6 mm x 0.8 mm — about half the area of an SOD-323. Plan for automated pick-and-place; manual soldering requires a fine-tip iron and magnification. Store the reels in a dry cabinet — the small body wicks moisture quickly, and reflow without bake risks popcorning.","metaTitle":"ESD5Z5.0T1 onsemi ESD Protection Diode – Obsolete, SOD-523","metaDescription":"onsemi ESD5Z5.0T1 Zener ESD protection diode, 5V reverse standoff, 18.6V clamp, 80pF, SOD-523.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SC-79, SOD-523","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"174W","Base Product Number":"ESD5","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"80pF @ 1MHz","Supplier Device Package":"SOD-523","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.2V","Voltage - Clamping (Max) @ Ipp":"18.6V","Voltage - Reverse Standoff (Typ)":"5V (Max)","Current - Peak Pulse (10/1000µs)":"9.4A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32a7aa25708c44b218e59a0ef208ee83.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the ESD5Z5.0T1 or check stock?","answer":"The ESD5Z5.0T1 is obsolete, so we source it through our independent supply network.
