That 1500W rating means it can clamp a transient on a 5V rail without collapsing — the clamping voltage at peak pulse current is 10.5V max, which keeps downstream silicon inside its absolute-max rating for most 5V logic families. The breakdown voltage range starts at 6.45V minimum, so the diode begins conducting just above the 5.8V standoff, leaving a narrow window before the clamp engages. This is a general-purpose transient suppressor — not a power-line protection device, so it's suited for signal or low-voltage DC rails rather than mains-side clamping. ## DO-201AD axial package – mounting and thermal note The DO-201AD (axial-lead) package is a through-hole form factor. The junction temperature range spans -65°C to 175°C, which covers military and industrial thermal extremes — the 1500W pulse rating assumes the leads are soldered into a PCB with adequate copper area to sink the heat. ## Obsolete status – planning the BOM transition onsemi lists the 1N6267A as Obsolete. No official successor or cross-reference is published. If you are qualifying a replacement, look for a Zener TVS in the same DO-201AD package with a 5.8V standoff and 1500W peak pulse rating. The Mosorb™ series includes other voltage variants, but the 1N6267A is the only 5.8V unit in that family — a parametric search across onsemi's current TVS portfolio is the next step.","metaTitle":"1N6267A onsemi Mosorb™ Zener TVS Diode – Obsolete, 1500W","metaDescription":"1N6267A onsemi Mosorb™ Zener TVS diode, 1500W peak pulse power, 5.8V standoff, DO-201AD axial.
