The -55°C to 150°C junction temperature range covers under-hood and engine-bay deployment where ambient can hit 125°C with self-heating margin. ## Package and board-fit for automated assembly Housed in a DO-214AC (SMA) surface-mount package, the SMAJ28AQ-13-F uses the standard SMA footprint with the cathode band marking orientation.","metaTitle":"SMAJ28AQ-13-F Diodes Inc Automotive TVS, 400W, 28V, DO-214AC","metaDescription":"SMAJ28AQ-13-F Zener TVS from Diodes Inc, AEC-Q101 qualified, 400W peak pulse, 28V standoff, DO-214AC.
