Product details

What the 6.4 V standoff and 11.3 V clamping mean for your protection circuit

The 1.5SMC7.5A-E3/57T: The reverse standoff voltage of 6.4 V defines the working rail the TVS sees in normal operation — it sits reverse-biased below this level and does not conduct.

SMC/DO-214AB package and surface-mount fit

The DO-214AB (SMCJ) footprint is the common medium-current TVS land pattern — the cathode bar in the package marking identifies the polarity face, which matters for reflow orientation. Supplied on tape-and-reel and cut-tape; the Cathode band on the body must face the correct polarity pad before reflow.

Frequently asked questions

What series is the 1.5SMC7.5A-/57T from and what does TransZorb mean?

It belongs to the 1.5SMC series — Vishay's TransZorb® is their avalanche-rated unidirectional TVS construction, as opposed to a conventional Zener. The TransZorb® designation indicates the part is qualified for repetitive transient clamping without degradation, which is the key distinction for protection applications.
