At 38.9 V maximum clamping voltage with a 38.6 A 10/1000 µs surge, the diode clamps the spike low enough to protect downstream semiconductors whose absolute-max inputs sit below that level — this 1.5 kW peak rating is the headroom spec that decides whether the part survives a typical AC-line fault or a motor-inductive kicker. ## DO-214AB SMC package and thermal margin The DO-214AB (SMC) outline is the mid-size TVS package — larger than the SMA, smaller than the SMB — which matters for board layout because the SMC landing pad lands on a copper pad that sets the thermal impedance to ambient; the datasheet derating curve ties the 1500 W 10/1000 µs peak-pulse rating to a specific board footprint and airflow. Operating junction temperature runs to 150 °C with a rated -55 °C cold start — the wide TJ window covers both outdoor/wide-temp industrial enclosures and any board that sees self-heating from clamping events without the device stepping out of spec. Surface-mount topology and tape-and-reel / cut-tape packaging fit standard SMT line placement — no through-hole hand-solder step on a production run.","metaTitle":"1.5SMCJ24A_R1_00001 Panjit TVS Diode, 38.9V Clamp, 1500W","metaDescription":"Panjit 1.5SMCJ24A_R1_00001 unidirectional Zener TVS, 24V standoff, 38.9V clamping, 38.6A peak pulse.

It protects a single polarity only; bidirectional protection requires a separate bidirectional variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ24A_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ24A_R1_00001 when reusing this data.
