The DO-201AA axial package (also known as DO-27) is a through-hole footprint common in power supplies and industrial control boards where leaded assembly is preferred over surface-mount. ## Clamping voltage and breakdown margin Minimum breakdown voltage is 456V, so the device starts clamping just above the standoff level, ensuring the protected circuit sees a transient limited to 658V. The 2.28A peak pulse current rating at 10/1000µs defines the surge it can absorb without failing — useful for a 400V DC bus or three-phase rectifier output where inductive kickback is the main threat.","metaTitle":"Vishay 1.5KE480A-E3/73 TransZorb TVS, 1500W, 658V Clamp","metaDescription":"Vishay 1.5KE480A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse power, 658V clamping, DO-201AA axial.
