The 43.6 V reverse standoff voltage (V_RWM) is the maximum continuous DC voltage it blocks without conducting. That 70.1 V clamp is the number that matters for the protected circuit's voltage tolerance — if the downstream silicon's abs-max is 75 V, this TVS keeps it inside the safe zone. With no power-line protection rating, this part is intended for DC signal or low-voltage bus transient suppression — think 24 V or 48 V industrial control rails, telecom line cards, or battery-powered equipment — not for AC mains clamping. ## Through-hole DO-201AE — field-swappable with a soldering iron The DO-201AE axial package is through-hole, which means it can be replaced on site with basic hand tools — a soldering iron and solder wick. No hot-air station, no reflow profile. The cathode band is clearly marked on the body, so orientation is one-look obvious even without a bench.","metaTitle":"1.5KE51A-TP 1500W Zener TVS, DO-201AE, 70.1V Clamp","metaDescription":"1.5KE51A-TP from Micro Commercial Co: 1500W peak pulse power, 43.6V standoff, 70.1V clamp.
