As a standard TransZorb series device, the 1.5SMC30A-M3/57T is widely inventoried across the supply chain; the date-code and lot traceability should be consistent with Vishay's factory markings, and the laser-etched marking on the DO-214AB body is a fingerprint that a counterfeit-detection X-ray can verify against known good units.

Frequently asked questions
What is the closest pin-compatible alternative to 1.5SMC30A-M3/57T in this Circuit Protection family?
Within the same 1.5SMC TransZorb series, the 1.5SMC30A (non-M3 suffix) shares the identical DO-214AB package, same 25.6V standoff and 41.4V clamp, but may differ in the plating or termination finish — the M3/57T variant uses a matte-tin plating for lead-free soldering compliance. Both are pin-compatible drop-in replacements on the same PCB footprint.
