The clamping ceiling is 27.6V at the rated peak pulse current of 21.7A (10/1000µs waveform). That 27.6V clamp is the number the downstream silicon sees; if your IC's absolute max is 30V, this part buys you 2.4V of headroom at the surge peak. The DO-214AA (SMB) package keeps the footprint small, but the board copper area under the cathode tab directly affects the thermal impedance; a skimpy pad will raise the junction temperature and reduce the effective pulse capability. ## Active production — no EOL scramble needed Microchip lists the SMBJ17AE3/TR13 as Active. No last-time-buy window, no successor to evaluate.","metaTitle":"SMBJ17AE3/TR13 TVS Diode – 18.9V Breakdown, 27.6V Clamp","metaDescription":"Microchip SMBJ17AE3/TR13 Zener TVS, 600W peak pulse, 17V standoff, 18.9V min breakdown, 27.6V clamp.
