For a 12 V automotive battery line, that 128 V standoff looks high, but this part is sized for 48 V or 72 V bus rails where transients can exceed 150 V. The DO-214AB (SMC) package handles the thermal pulse — the large copper tab on the bottom side conducts heat into the PCB pad, so the board layout's copper area directly sets the derating. Surface-mount assembly means reflow profile matters; the -65°C to 150°C junction range covers under-hood automotive ambient. ## Automotive qualification and sourcing posture The TransZorb® trademark is Vishay's branded TVS technology; the 'HE3' suffix in the order code flags the AEC-Q101 variant.","metaTitle":"1.5SMC150AHE3/9AT TVS Diode, 1500W, 128V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC150AHE3/9AT Zener TVS diode, 1500W peak pulse, 128V reverse standoff, AEC-Q101 qualified.
