1500W bidirectional clamping — what the ratings mean for your protection rail
The 1.5SMC16CA_R1_00001: The 13.6V reverse standoff voltage means it stays transparent on a 12V nominal rail; the 22.5V clamp voltage defines the maximum transient the downstream circuitry sees before the TVS conducts. At 67A peak pulse current, the device can sink a significant surge without failing open — the limiting factor in a real layout is the PCB trace inductance between the TVS and the protected load, not the silicon itself.
Board-fit and thermal integration
Housed in a DO-214AB (SMC) surface-mount package, the part's cathode tab is the primary heat path. The -55°C to 150°C junction temperature range suits outdoor or under-hood deployments where the ambient sees wide swings. Power line protection is not listed as a primary use — the device is intended for general-purpose signal or low-voltage DC rail clamping.
