Product details

1500W bidirectional TVS for general-purpose rail protection

The 1.5SMC30CA R7G: The 38A peak pulse current rating (at 10/1000µs) tells you the diode can handle that current without failing — useful when sizing the upstream fuse or PTC.

No power-line protection feature (it's a TVS, not a filter), so pair it with a common-mode choke if you need EMI suppression too.

Active lifecycle and sourcing

No official second-source or pin-compatible alternative is recorded in this ledger, but the 1.5SMC series is a standard footprint — many TVS diodes in DO-214AB from other manufacturers are drop-in replacements if you verify the breakdown voltage window.
