The 234 V clamping voltage at 6.7 A means the downstream silicon sees no more than 234 V across the transient; for a 200 V-rated MOSFET or IC, that leaves 34 V of headroom before the abs-max rating is hit. ## Temperature grade and package reality Supplied in bulk, not tape-and-reel — this matters for automated assembly: the part feeds from a tube or tray feeder, not a reel. Confirm the feeder compatibility before committing the pick-and-place program. ## Where it fits and where it does not Marked as General Purpose and explicitly not rated for power line protection — this TVS is intended for DC power buses, signal lines, and low-voltage AC circuits, not for 120/230 VAC mains input protection where a higher standoff and MOV or gas tube would be specified. For a 145 V bus (e.g., a 48 V telecom rectifier output after a boost stage, or a 120 V DC motor drive rail), the 1.5KE170CA B0G clamps before the downstream electrolytic capacitor's voltage rating is exceeded — the 234 V clamp is well below a 250 V-rated cap's surge limit.","metaTitle":"1.5KE170CA B0G TVS Diode, 1500W, 145V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE170CA B0G bidirectional TVS, 1500W peak pulse, 145V standoff, 234V clamping.
