The 11V reverse standoff means it stays off the 11V DC rail until a surge pushes the voltage above the 12.2V breakdown threshold. For a 12V or 11V rail, this is the right clamp voltage — it won't trigger on normal ripple but catches spikes before they reach downstream silicon. ## DO-214AC (SMA) – common footprint, easy rework Packaged in DO-214AC (SMA), a surface-mount package with a 0.065-inch body width. The pad layout matches standard SMA footprints used across the industry. Reflow profile is typical for lead-free solder — 260°C peak. The Tape & Reel delivery feeds pick-and-place directly. That covers cold-start in outdoor enclosures and hot spots near power stages. The 150°C upper limit gives margin above typical 85°C ambient when derating for self-heating during a pulse.","metaTitle":"SMAJ11E3/TR13 TVS Diode – 500W, 11V Unidirectional, DO-214AC","metaDescription":"SMAJ11E3/TR13 from Microchip: 500W peak pulse power, 11V reverse standoff, unidirectional Zener TVS in DO-214AC (SMA).
