It handles a peak pulse power of 600W (10/1000µs waveform) and clamps the voltage to a maximum of 18.2V while conducting up to 33A of peak pulse current. This means for a 11V supply line, it will start conducting around 12.2V (the breakdown voltage) and hold the voltage below 18.2V during a surge, protecting downstream ICs that might have a 14V or 16V absolute maximum rating. ## Package and field-service fit It comes in a standard DO-214AA (SMB) surface-mount package. This is a common footprint for TVS diodes in this power class, and it's something you can swap on site with a basic soldering iron and some wick — no hot-air station required. The unidirectional orientation (single channel) is clearly marked on the body with a cathode band, so it's hard to get it wrong even without a bench. ## Where it goes and where it doesn't Rated for general-purpose use across a wide temperature range from -55°C to 150°C (junction), so it's happy in outdoor gear, industrial control boxes, or automotive modules (though not AEC-Q certified per the listing). Note the 'Power Line Protection' flag is 'No' — this part is meant for signal lines, low-power DC rails, or data interfaces, not for clamping mains or high-energy motor drive buses. For a 24V or 48V rail, you'd look at a higher standoff voltage in the same SMBJ family.","metaTitle":"SMBJ11A-13 TVS Diode, 600W, 11V Standoff, DO-214AA","metaDescription":"SMBJ11A-13 Zener TVS diode from Diodes Inc. 600W peak pulse, 11V standoff, clamps at 18.2V.
