Product details

7V standoff clamp in a SOD-523 body

The ESD5Z7.0T1G is a single-channel Zener ESD protection diode from onsemi, rated for a 7V (max) reverse standoff voltage and a 200W peak pulse power rating in the SOD-523 package.

Clamping voltage and capacitance trade-off

The 65pF typical capacitance at 1MHz is low enough for most general-purpose I/O lines up to a few MHz, but it will load high-speed interfaces like USB 2.0 or 100BASE-T — for those, look for a part with under 5pF. No power-line protection feature means this diode is intended for signal-line clamping only, not for DC rail crowbar protection.

Frequently asked questions

Is the ESD5Z7.0T1G obsolete or still active?

It is active — no end-of-life notice from onsemi. Normal distributor stock and no last-time buy urgency.

What is the difference between the ESD5Z7.0T1G and the ESD5Z5.0T1G?

The ESD5Z5.0T1G has a 5V reverse standoff voltage, while the ESD5Z7.0T1G is rated for 7V (max). Both share the same SOD-523 package and 200W peak pulse rating. Choose the 7V version for 3.3V or 5V rails where the standoff margin is needed.
