1500W bidirectional TVS for general-purpose rail clamping
The 1.5SMC43CA R7G: The 36.8 V reverse standoff means it sits across a 36 V rail without conducting leakage; clamping at 59.3 V ensures downstream silicon sees a hard ceiling during a transient. Bidirectional construction makes it a single-device solution for AC lines or DC rails that see reverse polarity — no need for series diodes or two unidirectional parts back-to-back.
Voltage ratings and pulse current handling
Breakdown voltage (min) is 40.9 V at the test current — this is the knee where the device starts conducting.
DO-214AB (SMC) surface-mount package
The large body and copper tab handle the thermal pulse of the 10/1000 µs surge without exceeding the junction limit. Tape-and-reel packaging (R7G suffix) suits automated pick-and-place.
