Peak pulse power and clamping — what 1500 W means on the line
The 1.5SMC110CA: The 1500 W rating is the peak pulse power dissipation for a 10/1000 µs exponential waveform — the standard TVS test condition (IEC 61000-4-5).
Bidirectional clamping for symmetrical protection
That makes it the natural choice for AC signal lines or DC rails where reverse-polarity events are possible — no need for two diodes back-to-back. On a 94 V rail, the diode sits transparently until a transient pushes the voltage above the 105 V minimum breakdown threshold.
DO-214AB (SMC) package and board-fit note
Housed in the DO-214AB (SMC) package, the 1.5SMC110CA is a surface-mount device with a JEDEC-standard footprint shared by many 1500 W TVS diodes. The wide range suits outdoor telecom, power supplies, and motor-drive transient protection where ambient temperatures can exceed 85°C.
