Breakdown occurs at a minimum of 8.65V, so the diode stays out of conduction below that threshold, keeping leakage negligible during normal operation. ## Axial DO-201AA package and board fit Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE9.1A-/73 is a through-hole part that solders into standard 0.040-inch diameter holes on a 0.200-inch lead spacing. The axial body is well suited for point-to-point wiring or PCB mounting where the leads can be formed to fit the hole pattern. The package is supplied in Tape & Box (TB) format, which means it ships in a box with taped leads for automated insertion equipment — not a reel. The supplier device package code is simply \"1.5KE\", matching the industry-standard DO-201 outline. The base product number is 1.5KE9.1, meaning the suffix -/73 denotes the packaging variant (Tape & Box) and RoHS compliance. For BOM planning, the same die is available in other package formats under the 1.5KE9.1 base — useful if your pick-and-place prefers a different carrier.","metaTitle":"1.5KE9.1A-E3/73 Vishay TransZorb TVS, 1500W, 13.4V Clamp","metaDescription":"Active Vishay 1.5KE9.1A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 13.4V clamp at 112A.
