DO-214AB SMC Zener TVS for automotive and telecom transient protection
The 1.5SMC68AHM3/H is a unidirectional Zener-based transient voltage suppressor (TVS) — branded TransZorb® — qualified to AEC-Q101 for automotive deployments. The DO-214AB (SMC) surface-mount package is the standard medium-power TVS footprint; the supplier device package designation matches the case size exactly, so the land pattern follows the SMC land guide without custom geometry. At 58.1V reverse standoff, the device idles below breakdown in normal 48V automotive or 52V telecom rail operation. Once a surge pushes the line above the 64.6V minimum breakdown, the TVS clamps at 92V maximum — the clamping voltage at the rated 16.3A 10/1000 µs surge current.
Sourcing posture — active lifecycle, BOM alignment
The part is listed Active under Vishay General Semiconductor - Diodes Division with base product number 1.5SMC68. The base number is the sourcing alignment key — BOM systems quoting any 1.5SMC68xx variant can cross-reference to this exact date/packing code at RFQ. Tape-and-reel packaging supports automated assembly flow; confirm reel quantity per the ordering standard before committing a production build.
