AEC-Q101 qualification and an automotive-grade rating mean this part is screened for reliability in 48 V board nets, telecom line cards, and industrial DC bus protection where the transient energy exceeds what a smaller SMC package can absorb. ## Clamping voltage and surge current — what the ratings mean for the BOM At 102 V reverse standoff the TVS draws negligible leakage under normal operating conditions, so a 48 V or 72 V telecom bus running at 100 V max stays below the standoff threshold and the device is effectively invisible until a transient triggers it. The 114 V minimum breakdown voltage ensures the part does not conduct prematurely at the upper end of the nominal rail tolerance — a 100 V bus with 10 % regulation peaks at 110 V, still below the breakdown floor. ## Through-hole DO-201AA package and board integration Housed in a DO-201AA (DO-27) axial-lead package, this TVS is a through-hole part intended for point-of-entry transient suppression on terminal blocks, bus bars, or secondary-side rectifier outputs where the 1.5 kW pulse demands a leaded body with lower thermal resistance than a surface-mount equivalent. ## Active production and sourcing posture Tape-and-reel packaging is standard for this axial-lead part.","metaTitle":"Vishay 1.5KE120AHE3_B/C 1.5kW TransZorb, 102V Standoff","metaDescription":"Automotive AEC-Q101 TransZorb TVS, 1500W peak pulse, 102V reverse standoff, 165V clamp.
