Clamping is specified at 42.1V maximum at the 9.5A peak pulse current — this is the voltage the downstream electronics see during a transient. The DO-214AC (SMA) surface-mount package keeps the thermal path short to the PCB copper pour, which is the primary heatsink for the 400W pulse. ## AEC-Q101 qualification and automotive deployment This part carries AEC-Q101 qualification, the automotive-grade standard for discrete semiconductors. The -55°C to 150°C junction temperature range covers under-hood and cabin environments — the 150°C ceiling is the die temperature, not the ambient, so the board's thermal design must keep the junction below that under repetitive pulse conditions. ## Sourcing and compliance As an AEC-Q101 device, the part ships with full lot traceability and the manufacturer's standard RoHS/REACH compliance documentation.","metaTitle":"SMAJ26AQ-13-F Diodes Zener TVS, 400W, DO-214AC","metaDescription":"SMAJ26AQ-13-F Diodes Inc Zener TVS, 400W peak pulse, 26V standoff, AEC-Q101, DO-214AC.
