Product details

Unidirectional TVS clamp — what the standoff, breakdown and clamping triad means

The 1.5SMC91A/TR7 is a unidirectional Zener-type TVS diode in the DO-214AB (SMC) package, protecting a circuit by clamping transients above its breakdown threshold. The reverse standoff voltage of 77.8 V sets the normal working rail — the device sits idle below this and activates once the transient pushes the line into breakdown above 86.5 V minimum.

The part ships on tape and reel or cut tape, suitable for standard SMT pick-and-place.

Frequently asked questions

What type is the 1.5SMC91A/TR7 — and what series does it belong to?

It is a Zener-type unidirectional TVS diode in the 1.5SMC series, housed in the DO-214AB (SMC) surface-mount package. The single unidirectional channel means it protects one polarity only — it does not handle bidirectional AC transients.
