The 1.5kW power rating is the product of clamp voltage and peak current — derate this above 25°C ambient per the datasheet curve, as junction temperature directly limits the energy the part can absorb in a single event. The AEC-Q101 qualification means the part passed thermal cycling, high-temperature reverse bias, and ESD stress tests required for PPAP submission. An OEM auditor will ask for the AEC-Q101 certificate and the lot-specific PPAP documentation before signing off. ## Package and board footprint for layout The layout engineer should connect the tab to a ground plane with adequate copper area — the 1.5kW pulse energy dissipates through this thermal pad, not through the device leads. Tape & Reel packaging supports high-volume pick-and-place. ## Sourcing posture and active status Listed as Active by Diodes Incorporated.","metaTitle":"SMCJ70AQ-13-F Diodes Inc TVS, 70V, 1.5kW, AEC-Q101","metaDescription":"SMCJ70AQ-13-F from Diodes Incorporated — 70V standoff, 1.5kW peak pulse, AEC-Q101 qualified.
