1500W peak pulse power in a DO-13 can
The 1N6054/TR: That 1500W rating means it can absorb a 24A pulse while clamping at 61.9V max — enough to protect a 34V DC rail from lightning-induced surges or inductive load dumps without the part self-destructing.
Voltage window and bidirectional clamping
The reverse standoff voltage is 34V typ — the DC bus or signal line rides here under normal operation. If a transient pushes the line above 38.7V min, the Zener breakdown triggers conduction. The clamping voltage is capped at 61.9V max at the rated 24A peak pulse current.
