Housed in the DO-214AB (SMC) surface-mount package, the SMCJ43CA-13 occupies a standard footprint common across the SMCJ series. The SMC body size supports the 1.5 kW power dissipation without requiring an external heatsink — the copper pad area on the PCB and the solder joint to the cathode tab set the thermal resistance. The package is supplied in Tape & Reel (TR) and Cut Tape (CT) options, compatible with standard pick-and-place and reflow profiles. The device is not rated for power line protection — the spec explicitly notes no power line protection, so it is best suited for signal, data, and low-power DC rail applications where fast clamping is needed.","metaTitle":"SMCJ43CA-13 Diodes Inc TVS Diode, 1.5 kW, Bidirectional, SMC","metaDescription":"SMCJ43CA-13 bidirectional Zener TVS diode, 1500W peak pulse power, 43V standoff, 69.4V clamp.

The breakdown starts at 47.8 V minimum, so the diode does not conduct during normal operation, and the 69.4 V clamp provides a safety margin for common 60 V-rated downstream components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMCJ43CA-13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMCJ43CA-13 when reusing this data.
