The 7.5A peak pulse current figure is the current through the device at the clamping voltage — it is the surge the diode can safely shunt to ground. ## AEC-Q101 — the qualification an OEM auditor expects AEC-Q101 qualification means this TVS has passed the automotive discrete semiconductor stress tests: temperature cycling, high-temperature reverse bias, and ESD robustness, among others. For a Tier-1 supplier submitting a PPAP package, the SMAJ33AQ-13-F carries the grade documentation the customer's quality team will ask for. ## DO-214AC (SMA) — board-fit and thermal note The DO-214AC (SMA) package is a standard surface-mount footprint for TVS diodes. For the 400W pulse rating, a pad of at least 30 mm² on a standard FR4 board is typical to keep the die temperature within the 150°C limit during repetitive surges. The part is unidirectional (one channel), so the cathode is marked and the anode is on the opposite end.","metaTitle":"SMAJ33AQ-13-F Diodes Zener TVS, 400W, DO-214AC","metaDescription":"SMAJ33AQ-13-F Diodes Inc Zener TVS, 400W peak pulse, 33V standoff, AEC-Q101 qualified, -55°C to 150°C.
