Breakdown occurs at a minimum of 133 V, and the clamping voltage is held to 193 V maximum at the 7.9 A peak pulse current. ## Package and board-fit for the SMC footprint Housed in the DO-214AB (SMC) package, a standard surface-mount footprint for TVS diodes rated above 1 kW. The large copper tab on the bottom side conducts heat into the PCB pad — the board copper area under the package sets the effective thermal resistance for repetitive surge duty. Rated for operation from -55°C to +150°C junction, covering the full industrial temperature range and most automotive under-hood environments where the ambient near the PCB can exceed 105°C. The wide-temperature spec is typical of a Zener-based TVS structure that maintains stable breakdown voltage across the thermal envelope.","metaTitle":"SMCJ120A-13-F Diodes Inc TVS Diode, 1500W, DO-214AB","metaDescription":"SMCJ120A-13-F TVS Zener diode from Diodes Inc, 120V standoff, 193V clamp, 1500W peak pulse.

For a shorter pulse (e.g. 8/20 µs from an ESD event), the diode can absorb a much higher peak power. The real protection envelope is defined by the clamping voltage (193 V max) and the peak pulse current (7.9 A) at that waveform."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMCJ120A-13-F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMCJ120A-13-F when reusing this data.
