The 1N6267-E3/54: The 1N6267-/54 is a unidirectional Zener-based transient voltage suppressor (TVS) from Vishay's TransZorb® series, housed in the DO-201AA axial package and supplied on tape-and-reel. The 1500 W rating is a 10/1000 µs waveform figure; the clamping voltage at that pulse width tells you what the downstream circuit sees when the event hits. The −55 °C to 175 °C junction temperature range gives wide thermal headroom for transient events — a 175 °C TJ ceiling above the typical 85 °C ambient in an enclosed panel means you have margin before the diode thermally shuts down.

Frequently asked questions
What is 1N6267-/54 used for in a circuit?
It is a unidirectional Zener TVS (TransZorb®) that clamps voltage spikes on a signal or power rail. The 5.5 V standoff, 10.8 V clamping ceiling, and 139 A peak pulse capacity make it suited for secondary protection on low-voltage rails that need a fast-clamp response to surges.
Does a replacement exist for the 1N6267-/54?
The base product number 1N6267 and the 1.5KE series are the logical search starting points for a pin-compatible equivalent in the same DO-201AA package, but any cross-reference should be verified against your clamping voltage and peak pulse current requirements before committing a BOM position.
