Rated for 1500 W of peak pulse power (1.5 kW), this diode absorbs the energy of a typical automotive load-dump or inductive kickback transient without failing short. The 10/1000 µs waveform is the industry-standard TVS test pulse — the part's 60 A rating applies to that specific pulse shape and duration. ## Automotive-grade construction and thermal envelope Housed in a DO-201AA (DO-27) axial-lead through-hole package. The bulk copper lead frame and large junction area support the 1.5 kW pulse without bond-wire fusing. The through-hole form factor is preferred in high-reliability or high-vibration designs where SMD solder joints could crack — the axial leads are bent and soldered into the board, then potted or conformal-coated. Single unidirectional channel — the cathode band marks the anode. Polarity matters: the diode conducts only when the surge voltage exceeds the breakdown in the forward direction; reverse connection shorts the rail. For AC or bidirectional protection, two devices back-to-back or a dedicated bidirectional TVS is needed. The part is currently in the standard product portfolio and available through authorized distribution channels. Sourced to order against the BOM line. The AEC-Q101 traceability chain means each reel carries a date-code and lot number that can be traced back to the wafer fab and assembly site — a critical requirement for automotive PPAP submissions.","metaTitle":"1.5KE18AHB0G TVS Diode, AEC-Q101, 1.5 kW, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE18AHB0G Zener TVS diode, 1500W peak pulse, 15.3V standoff, AEC-Q101 automotive grade.
