The single-channel construction protects one line per device. ## Obsolete — what that means for procurement Diodes Incorporated lists the SMAJ20CA-13 as Obsolete. No official successor order code is recorded. Housed in the DO-214AC (SMA) surface-mount package, with the supplier device package also designated SMA. The footprint is standard for this JEDEC outline — the cathode band (or bidirectional marking) orients the part on the pad.","metaTitle":"SMAJ20CA-13 TVS Diode, 400W Bidirectional, DO-214AC","metaDescription":"Obsolete SMAJ20CA-13 from Diodes Inc — 400W peak pulse, 20V standoff, 32.4V clamp, DO-214AC.
