The clamping voltage at peak pulse current is 13.4V max. That means it triggers well below a 12V rail — it is designed for 5V or 7.5V nominal buses, not for 12V protection. If you need a 12V clamp, look at the P6KE12A or similar in the same family. The breakdown voltage minimum is 8.65V, so the device starts conducting somewhere between 8.65V and the clamping ceiling. The 45A peak pulse current rating is measured with an 8/20µs waveform — a common surge shape for industrial transient testing. ## Through-hole axial — field-swap friendly The axial package is a through-hole part — no hot-air station needed. Polarity is marked by the cathode band; orientation is obvious enough to get it right on site with a multimeter check.","metaTitle":"P6KE9.1A onsemi Zener TVS — Obsolete, 600W, Axial","metaDescription":"P6KE9.1A onsemi Zener TVS diode, 600W peak pulse power, 7.78V standoff, T-18 axial package.
