1500 W bidirectional TVS for 24 V automotive buses
The 1.5SMC24CAHM6G: It clamps at 33.2 V maximum and has a 20.5 V reverse standoff voltage, making it a fit for protecting 24 V nominal automotive power rails and signal lines against transients like load dump and inductive kickback.
AEC-Q101 qualification and temperature range
This part carries AEC-Q101 qualification, meaning it has passed the automotive-grade stress tests for temperature cycling, high-temperature reverse bias, and ESD robustness. The bidirectional configuration (single channel) means the device clamps both positive and negative transients symmetrically, which is useful on AC-coupled or floating signal lines where polarity is not fixed.
Peak pulse current and clamping performance
The minimum breakdown voltage is 22.8 V, so the part starts conducting well below the 33.2 V clamp — this gives margin for the TVS to absorb energy before the protected circuit sees overvoltage.
The package is rated for the full 1500 W pulse without external heatsinking, relying on the PCB copper area for thermal dissipation.
