At 7.13 V minimum the zener avalanche kicks in, which is the breakover threshold. The clamping ceiling at peak pulse current is 11.3 V — that is what the downstream load sees at 134.5 A of 10/1000 µs surge current. The Tj rating of -55 °C to 150 °C places this in the industrial temperature band — it survives a soldering transient hot-spot on the die without derating in a non-ventilated enclosure, so long as the board-level thermal path keeps the junction below the 150 °C limit during a clamping event. ## DO-214AB SMC package — what it demands of the board Surface-mount DO-214AB (SMCJ supplier package) requires a land pattern sized to the cathode bar — the anode/cathode silkscreen marking is the only polarity indicator on the body. Tape-and-reel and cut-tape packaging are both available. General-purpose classification means no special screening flow — this is the standard commercial grade, not a hi-rel or automotive-screened variant.","metaTitle":"Littelfuse 1.5SMC7.5A, 6.4V TVS Diode, 1500W","metaDescription":"Littelfuse 1.5SMC7.5A unidirectional TVS diode, 6.4V standoff, 7.13V min breakdown, 11.3V clamping at 134.5A peak pulse, 1500W peak, DO-214AB SMC.
