The DO-201AA axial package (DO-27 footprint) mounts through-hole and suits point-to-point or PCB wiring in modules where surface-mount reflow is not preferred.","metaTitle":"1.5KE9.1AHE3/51 Vishay TransZorb TVS, 1500W, Obsolete","metaDescription":"Obsolete Vishay 1.5KE9.1AHE3/51 TransZorb TVS diode, AEC-Q101, 1500W peak pulse, 13.4V clamping.
