Breakdown occurs at 10.5 V minimum, and the clamping voltage at peak pulse current is 15.6 V maximum — the protected circuitry sees no more than that during a transient. ## AEC-Q101 and the TransZorb series Part of the Automotive, AEC-Q101 qualified TransZorb series. AEC-Q101 certifies the device for automotive-grade stress screening and reliability — relevant for under-hood or body-control modules that must survive load-dump and inductive-switching transients. The operating junction temperature range spans -55°C to 175°C, covering the full automotive ambient envelope. Peak pulse current capability is 96.2 A for the 10/1000 µs waveform. This figure, combined with the 1500 W power rating, tells you the surge it can absorb before the junction temperature exceeds the limit. ## Package and board fit Through-hole mounting in a DO-201AA (DO-27) axial-lead package. The axial body is 1.5KE series standard.","metaTitle":"1.5KE11AHE3/51 Vishay TVS, 1.5kW, 9.4V Standoff","metaDescription":"Vishay 1.5KE11AHE3/51 obsolete TVS diode, 1500W peak pulse, 9.4V reverse standoff, AEC-Q101.
