Housed in the standard DO-214AC (SMA) surface-mount package, it places on a standard footprint with no tombstoning risk at typical reflow profiles — the MSL rating (not stated in this record, but standard for this package class) should be confirmed before the bake step if the part has been in storage beyond the floor-life.","metaTitle":"SMAJ20AQ-13-F Diodes Inc TVS Diode, 400W, AEC-Q101, SMA","metaDescription":"SMAJ20AQ-13-F automotive TVS diode, 20V standoff, 32.4V clamp, 400W peak pulse, AEC-Q101 qualified.
