Its 70 V reverse standoff voltage means it clamps transients on 48 V or 60 V DC buses — not 5 V or 12 V rails. The breakdown voltage starts at 77.8 V, and the clamping voltage is held to 125 V at the 4 A peak pulse current. Sourcing is straightforward — we can quote against your BOM quantity and lead time at the time of request.","metaTitle":"SMAJ70E3/TR13 TVS Diode – 500W, 70V Standoff, DO-214AC","metaDescription":"SMAJ70E3/TR13 Zener TVS diode, 500W peak pulse power, 70V reverse standoff, DO-214AC (SMA) surface mount.
