What 1500W peak pulse and 113V clamping mean for the rail
The 1.5SMC82AS_R1_00001 is a unidirectional Zener-based transient voltage suppressor holding 70.1V reverse standoff — the rail voltage it guards must sit below this to stay in the clamping zone. Rated 1500W peak pulse, the part survives one high-energy transient event and resets — it is not a crowbar that latches, but a clamp that limits.
DO-214AB SMC package and the field-rework angle
The SMC (DO-214AB) is a standard tape-and-reel and cut-tape surface-mount package — hot-air or IR rework is routine for any shop with a reflow oven, and the common cathode orientation is unambiguous once the stripe is identified on the reel label. Rated for surface-mount assembly, the part reflows at the standard lead-free profile.
General purpose classification means this is not automotive-qualified (AEC-Q101 is absent from the record) — do not drop it into an under-hood ECU without confirming the qualification requirement with the OEM. Power line protection is listed as No, so this is not a bus-protection TVS; it guards a signal rail or a local node. The single unidirectional channel confirms it handles one polarity — if the protected rail sees negative transients, a bidirectional variant is required instead.
Active status and what it means for sourcing
No last-time-buy date or EOL notice appears in the ledger for this code, so long-term sustainment sourcing through the usual distribution channel is viable. Confirm availability and lead time against your BOM quantity at RFQ — no stock-holding claim is made on this page.
