Clamping chain: what 70V / 77.8V / 113V actually mean
The 1.5SMCJ70A-AU_R1_000A1: The 70V reverse standoff is the working voltage — the diode idles off and draws only leakage current at up to 70V DC, so downstream rails rated below that see no impact during normal operation.
Active status and sourcing posture
No second-source cross-reference is confirmed — confirm the BOM position before committing to a single-source for new designs. The part ships on tape-and-reel and cut-tape formats per the manufacturer orientation.
