ESD5Z2.5T1G

Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This datasheet covers the ESD5Z and SZESD5Z series of micro-packaged transient voltage suppressor diodes designed for ESD protection. The document defines scope, maximum ratings, and electrical characteristics for parts like the 2.5V, 3.3V, 5.0V, and 12V variants in SOD-523 packages. Key parameters include a working peak reverse voltage ranging from 2.5 to 12V, clamping voltages up to 25V, peak power dissipation of 240W at 8x20µs pulses, and an IEC 61000-4-2 ESD rating exceeding 16kV per human body model. These devices feature low leakage current, fast response times under 1ns, and are RoHS compliant.
