The operating junction temperature range spans -55°C to 150°C, covering the under-hood and cabin ambient extremes without derating the 400 W pulse capability at the high end. Breakdown voltage (V_BR) is specified at a minimum of 47.8 V, which is the point where the Zener junction starts to avalanche and conduct. The 69.4 V clamping voltage (V_C) is the maximum voltage the protected circuit sees when the TVS is shunting the full 5.7 A peak pulse current. With a single unidirectional channel, this part protects one rail per device — the cathode is the protected line, the anode goes to ground. For bidirectional protection on AC-coupled or bipolar rails, two devices or a dedicated bidirectional TVS would be needed. ## Package and board-fit: DO-214AC SMA The supplier device package is designated SMA, confirming the JEDEC-standard outline with a 2.6 mm body width and gull-wing leads. Tape-and-reel packaging supports automated pick-and-place assembly at volume.","metaTitle":"SMAJ43AQ-13-F Diodes Inc Zener TVS, 400W, DO-214AC","metaDescription":"SMAJ43AQ-13-F Diodes Inc Zener TVS diode, 400W peak pulse, 43V standoff, AEC-Q101 automotive grade.
