Product details

Zener ESD clamp in SOD-523 — 174 W peak pulse

The ESD5Z5.0T1G is a single-channel Zener-type ESD protection diode from onsemi, housed in the compact SOD-523 (SC-79) package. It clamps transients with a peak pulse power rating of 174 W and a breakdown voltage minimum of 6.2 V, making it suitable for general-purpose ESD suppression on signal or power lines up to 5 V.

Clamping voltage and capacitance at 1 MHz

Maximum clamping voltage at the peak pulse current is 18.6 V, and the diode presents 80 pF of capacitance at 1 MHz.

The base product number is ESD5Z5.0.

Surface-mount assembly in SOD-523 suits high-density PCB layouts where board space is tight.
