AEC-Q101 qualification means this part passed the full automotive stress battery: high-temperature reverse bias (HTRB), temperature cycling, and ESD robustness per the JEDEC standard. ## Package and board-fit for automated assembly Surface-mount mounting eliminates through-hole lead forming and wave-solder steps, reducing board assembly cost. The package is rated for 260°C peak reflow per JEDEC J-STD-020, typical for lead-free processes. The base product number 1.5SMC39 covers the full voltage variant family; the 'A' suffix indicates 5% tolerance on breakdown voltage, and the 'HR7G' suffix encodes the AEC-Q101 automotive grade and tape/reel packaging.","metaTitle":"1.5SMC39AHR7G Taiwan Semiconductor Zener TVS, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC39AHR7G Zener TVS diode, 1500W peak pulse, AEC-Q101 automotive grade, DO-214AB SMC package.
