This is the variant an OEM auditor expects to see in a PPAP submission — the base 1.5KE68A without the 'H' suffix lacks this certification. Rated for continuous junction operation from -55°C to 175°C, the device sits comfortably in the under-hood temperature band where ambient soaks above 105°C are routine. The 175°C TJ(max) ceiling gives margin above the 150°C typical for engine-bay electronics. ## 1500W peak pulse — clamping in the 12V/24V automotive bus At 58.1V reverse standoff, this diode stays transparent on a nominal 12V or 24V bus — the leakage current below the breakdown knee is negligible. When a load-dump or inductive kick drives the line above 64.6V (the minimum breakdown voltage), the device clamps at 92V maximum while shunting 17A of peak pulse current in the 10/1000µs waveform. The 'A' in the part number denotes the 5% tolerance variant (the breakdown voltage is specified as 64.6V min, 71.4V max). The 'H' suffix is the AEC-Q101 designation, and 'A0G' indicates the Tape & Box (TB) packaging format. ## DO-201 axial package — board integration notes The DO-201AA (also known as DO-27) is a through-hole axial package with a body diameter of approximately 5.3 mm and lead diameter of 1.0 mm. The cathode band is marked on the body; the leads are tin-plated copper for solderability.","metaTitle":"1.5KE68AHA0G TVS Diode, 1500W, AEC-Q101, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE68AHA0G automotive Zener TVS diode, 1500W peak pulse, 58.1V standoff, AEC-Q101 qualified.
