The DO-201AA axial-lead package (DO-27 equivalent) is a through-hole form factor — the leads absorb thermal cycling stress better than surface-mount in high-vibration environments, and the body handles the 1500 W pulse without cracking the encapsulation. ## Sourcing an obsolete part — the independent channel Since Vishay has discontinued this order code, the supply channel is independent surplus and excess inventory. No official successor is listed — the functional replacement is a parametric match from the same TransZorb family or a different manufacturer's TVS with the same 6.63 V standoff and 1500 W rating. Each lot is traceable and verified against the original Vishay specifications — the breakdown voltage window (7.38 V min) and clamping voltage (12.5 V max) are the key pass-fail criteria for incoming inspection.","metaTitle":"Vishay 1.5KE8.2CHE3/54 TVS Diode, 1500W, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE8.2CHE3/54 TransZorb TVS diode, 1500W peak pulse, 12.5V clamp, AEC-Q101.
