AEC-Q101 qualification means this part passed the full automotive reliability stress suite: high-temperature reverse bias, temperature cycling, and ESD robustness per JEDEC. ## Clamping voltage and pulse current — what they mean for the BOM The 70.1V maximum clamping voltage at 22A peak pulse current sets the voltage stress the downstream components must survive. A 48V bus controller or MOSFET rated at 80V Vds sits below this clamp — the TVS holds the transient below the device's absolute maximum, so the FET doesn't avalanche. The 48.5V minimum breakdown voltage ensures the diode doesn't conduct during normal 48V operation, only when a surge pushes the rail above that threshold. Single unidirectional channel means this diode protects one polarity — positive surges to ground. For bidirectional protection on AC or bipolar rails, you'd need two devices or a bidirectional variant. Tape & Reel packaging — standard 13-inch reel, quantity per reel varies by diameter. The base product number 1.5SMC51 covers the full voltage variant family; the HM6G suffix encodes the automotive AEC-Q101 grade and the specific packaging code.","metaTitle":"1.5SMC51AHM6G TVS Diode, 1500W, DO-214AB, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC51AHM6G Zener TVS, 1500W peak pulse, 43.6V standoff, DO-214AB, AEC-Q101 automotive grade.
