At the 6.7 A peak pulse current (IPP), the clamping voltage holds at 234 V maximum. That 234 V ceiling is what the downstream silicon sees — verify it stays below the absolute maximum rating of the protected components, including any derating for temperature. ## DO-201 axial package and board integration The DO-201AA (DO-27) axial-lead package is a through-hole form factor that handles the 1500 W pulse without the thermal limitations of a smaller surface-mount package. The leads are tin-plated copper; the body is molded epoxy with a flame-retardant rating per the series standard. The 'No Power Line Protection' flag in the spec means it is not rated for AC mains cross-coupled transients; use it on DC buses only. ## Active production and sourcing posture The base product number is 1.5KE170; the 'A' suffix denotes a 5% tolerance on the breakdown voltage (the standard 1.5KE170 without suffix is 10% tolerance). The 'B0G' suffix indicates the Bulk packaging option — verify your pick-and-place or hand-insertion process accepts axial Bulk rather than tape-and-reel or ammo-pack.","metaTitle":"1.5KE170A B0G TVS Diode, 1500W, 162V Breakdown, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE170A B0G Zener TVS diode, 1500W peak pulse power, 145V reverse standoff, 234V clamping.
