The 1.5SMC10CA-E3/57T: Minimum breakdown voltage is 9.5 V; the device starts conducting between 9.5 V and the 14.5 V clamp ceiling. The 8.55 V reverse standoff is the maximum DC voltage the TVS can hold without significant leakage — a 5 V rail sits well below this, so the part stays in high-impedance mode during normal operation. For shorter pulses (8/20 µs) the peak current capability is higher, but the 1500 W figure is the standard comparison point across TVS families.
DO-214AB (SMC) package and temperature range
Housed in the DO-214AB (SMC) surface-mount package, the part handles the 1500 W pulse without requiring a heatsink — the package's large copper tab conducts heat into the PCB copper plane.
Active lifecycle and sourcing posture
Supplied in Tape & Reel (TR) or Cut Tape (CT) packaging for automated pick-and-place assembly.
