The 171V minimum breakdown guarantees the avalanche region starts above the rail tolerance, so the diode stays off until a real surge arrives. ## DO-201AA axial package and board integration Housed in a DO-201AA (DO-27) axial leaded package, this TVS is a through-hole component intended for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The axial body allows it to sit inline with a bus bar or be inserted through a board and soldered on the opposite side — common in automotive power distribution junction boxes and ECU input protection stages. At 175°C the leakage current rises, but the die still clamps within the 246V ceiling — the derating curve in the datasheet governs pulse power above 25°C. ## Active lifecycle and sourcing posture As an AEC-Q101 qualified part, it comes with the full PPAP and change notification traceability that automotive Tier-1 buyers require. The laser etch on the body carries a date-code and lot trace; we screen for marking consistency and package integrity before shipment. ## Application boundary — not for AC power line primary protection This part is explicitly listed as having no power line protection capability — it is a secondary transient suppressor for DC rails and signal lines, not a primary mains surge protector. Use it downstream of a fuse or PTC on 154V DC buses, 110VAC rectified supplies, or automotive 24V/48V systems where the standing voltage is below the standoff rating. The bidirectional configuration means it clamps both polarities with a single device — useful on AC-coupled data lines or where the supply can be reverse-connected without damage.","metaTitle":"1.5KE180CAHE3_A/C TVS Diode, 1500W, Bidirectional, DO-201AA","metaDescription":"Vishay 1.5KE180CAHE3_A/C bidirectional TVS, 1500W peak pulse, 154V standoff, AEC-Q101 qualified.
