At 28V reverse standoff the diode sits off-state; once the line exceeds the 31.1V minimum breakdown the device clamps the transient, limiting the peak at the protected node to 45.4V maximum while conducting 33A peak pulse (10/1000 µs waveform). The 1.5 kW peak pulse rating sets the energy the part can absorb in that 10/1000 µ event — enough to absorb an ISO 7637-2 automotive load-dump transient without propagating the spike downstream to the ECU or sensor IC. ## 150°C junction rating for under-hood transient suppression The AEC-Q101 qualification covers temperature cycling, humidity bias, and electrical stress, giving the automotive supply chain the PPAP traceability and failure-in-time data that an AEC grade demands. ## Surface-mount SMC tape-and-reel for automotive assembly The part ships in tape-and-reel (TR) or cut-tape (CT) packaging, supporting standard SMT placement in high-volume ECU assembly.","metaTitle":"Panjit 1.5SMCJ28A-AU_R1_000A1 TVS Diode, 28V, 1.5kW SMC","metaDescription":"Panjit International Inc.
