Bidirectional (1 channel) means it clamps both polarities — no need to stack two unidirectional parts for a symmetrical bus; a single device covers the full AC or reversing-polarity DC rail. ## Automotive grade — AEC-Q101 in an engine-compartment temperature band Junction temperature rated to 150 °C — the upper bound sits well above the under-hood ambient ceiling, so a 105 °C module ambient leaves 45 °C of thermal margin before the junction limit is approached; derating curves in the Panjit datasheet quantify the remaining headroom for the design engineer. ## DO-214AB SMC — surface-mount protection on a standard footprint The SMC package is the dominant industry footprint for 1.5–3 kW TVS diodes — the land pattern is shared across multiple manufacturers, which is the key second-source consideration for a buyer managing single-source risk on a BOM line. Available in tape-and-reel and cut-tape packaging — the tape width and reel diameter are standard for this body size, but the exact lead-free / RoHS status should be confirmed at RFQ since automotive-grade tin-finish parts may carry different plating options than commercial equivalents.","metaTitle":"1.5SMCJ28CA-AU_R1_000A1 TVS Diode, 1.5kW, 28V Standoff","metaDescription":"Panjit automotive bidirectional TVS diode, 1500W peak pulse, 28V standoff, 45.4V clamping.

For any automotive ECU or module, using a non-AEC part on a protection line creates an argument with the quality team."},{"question":"How does a bidirectional TVS diode protect a circuit?","answer":"A bidirectional TVS presents a Zener-like characteristic in both polarities — when the line voltage exceeds the standoff threshold, the device avalanches and clamps the voltage at its specified maximum, shunting the surge current away from the protected load. For a 28 V rail the standoff is set below the normal operating maximum but above any expected transient, so the circuit sees no impact during normal operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ28CA-AU_R1_000A1","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/1.5SMCJ28CA-AU_R1_000A1 when reusing this data.
