The 47.8 V minimum breakdown voltage gives the guard band above the 43 V reverse standoff — the diode stays off during normal DC operation and only conducts when the transient pushes the line past that threshold. ## DO-214AB SMC — reflow profile and board integration The wide temperature span suits it for industrial and telecom environments where the ambient inside the enclosure can swing well past the commercial 85 °C mark. The single unidirectional channel means this variant protects one polarity — the cathode band on the package marks the protected side, and the anode connects to ground. For AC or bipolar lines, two devices or a bidirectional variant would be needed. ## Active production and sourcing posture The Tape & Reel packaging option (also available as Cut Tape) aligns with standard pick-and-place assembly.","metaTitle":"SMCJ43A-13 Diodes Inc TVS Diode, 1500W, Unidirectional","metaDescription":"Diodes Inc SMCJ43A-13 Zener TVS diode, 1500W peak pulse power, 43V standoff, 69.4V clamp, DO-214AB SMC package.
