The 27.8 A peak pulse current it can sink without failing is the figure that governs the upstream fuse coordination — if the fault energy exceeds the I²t rating of the TVS, the diode short-circuits rather than opens, which is the intended failure mode for a shunt protector. ## Breakdown and clamping — the guard band Minimum breakdown voltage is 37.1 V, so a 36 V nominal rail needs headroom to avoid nuisance triggering from normal ripple. The clamping ceiling of 53.9 V is the voltage the downstream components see during a surge — a 60 V-rated capacitor on the rail has margin, but a 50 V-rated part does not. ## Automotive qualification and sourcing posture Marked as active in production, the 1.5KE39AHE3_A/C carries AEC-Q101 qualification — the stress-tested reliability grade required for tier-1 automotive ECU BOMs. The TransZorb series is a known Vishay TVS family; the AEC-Q101 suffix means the parts shipped from the wafer fab have passed the additional screening and lot-traceability steps.","metaTitle":"1.5KE39AHE3_A/C Vishay TVS, 1500W, 33.3V Standoff","metaDescription":"Vishay 1.5KE39AHE3_A/C TransZorb TVS, 1500W peak pulse, 33.3V standoff, 53.9V clamp, AEC-Q101, active.
