An OEM auditor reviewing PPAP documentation expects this grade on any part in the engine bay or transmission controller. ## 1500 W peak pulse — what that clamp rating means for your rail At 139 A peak pulse current the clamp voltage holds at 11.3 V maximum, which keeps a 12 V battery rail or a 5 V logic supply inside the downstream IC's absolute-maximum rating during a load-dump or inductive kickback event. The reverse standoff voltage is 6.4 V, meaning the diode draws negligible leakage below that rail level. Breakdown starts at 7.13 V minimum, so a nominal 6.4 V supply sees no clamping during normal operation. ## DO-201 axial package — board-level fit Through-hole DO-201AA (DO-27) axial package — the leads insert into plated through-holes and take the mechanical strain of the transient current pulse better than a surface-mount package of the same power rating. The 0.95 mm lead diameter handles the 139 A surge without fusing. Single unidirectional channel — cathode band identifies the anode-to-ground orientation. For a positive transient on the protected rail the cathode connects to the rail; the anode goes to ground.","metaTitle":"1.5KE7.5AHA0G Taiwan Semi 1500W Zener TVS, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE7.5AHA0G automotive Zener TVS diode, 1500W peak pulse, 6.4V standoff, 11.3V clamp, DO-201 axial.
