Maximum clamping at 19.9V limits the voltage spike seen by the downstream load — a 7.9V window from breakdown to clamp that keeps most 12V-rated ICs within their absolute maximum ratings. ## Active production, surface-mount reel Supplied on Tape & Reel (TR) in the DO-214AA (SMB) package, a standard surface-mount footprint that reflows with the same profile as common SMB diodes.","metaTitle":"SMBJ12AE3/TR13 TVS Diode – 600W, 12V, DO-214AA, Active","metaDescription":"Microchip SMBJ12AE3/TR13 unidirectional Zener TVS, 600W peak pulse, 12V standoff, DO-214AA SMB.
