Product details

75 V rail clamp – Zener TVS in DO-214AC

Its 83.3 V minimum breakdown voltage ensures the device remains non-conductive during normal operation while triggering before the downstream circuitry sees damaging voltage. The 121 V maximum clamping voltage at the 4.1 A peak pulse current defines the worst-case voltage the protected load sees during a surge event.

500 W peak pulse – surge rating and thermal margin

Active lifecycle – standard distribution sourcing

Frequently asked questions

Is SMAJ75CAE3 bidirectional?

Yes, it is a single bidirectional channel, meaning it clamps transients of both polarities on the same line. This is suitable for AC signal lines or DC lines where reverse polarity protection is needed.

What is the peak pulse power of SMAJ75CAE3?

The peak pulse power rating is 500 W for a 10/1000 µs waveform. This defines the maximum transient energy the device can absorb without failure under standard test conditions.
