When a transient exceeds the breakdown voltage, the device clamps at 16.7V maximum — this is the voltage the downstream circuitry must survive. The 94A peak pulse current rating at 10/1000µs defines the energy-handling capacity for a single surge event. The 1500W peak pulse power is specified at 25°C; derate linearly above that per the datasheet curve. For a 12V DC bus, the 10.2V standoff leaves margin below the nominal rail while clamping well below typical semiconductor abs-max ratings (usually 20-24V for 12V-rated ICs). Housed in a DO-214AB (SMC) surface-mount package, the device operates over a -55°C to 150°C junction temperature range. The SMC footprint is standard for 1500W TVS diodes — the large copper pad on the cathode side (for unidirectional variants) or the body itself (bidirectional) conducts heat into the PCB plane. The base product number 1.5SMC12 identifies the voltage family; the CA suffix indicates bidirectional, and R7G denotes the reel and packaging code.","metaTitle":"1.5SMC12CA R7G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC12CA R7G Zener TVS, 1500W peak pulse, 10.2V standoff, 16.7V clamp, DO-214AB.
