Surge protection for 136 V rails
The 1.5SMC160A-M3/57T: The 152 V minimum breakdown voltage ensures the device triggers before the rail exceeds its safe operating area, while the 219 V clamp limits the voltage seen by the load during a surge event.
Package and thermal considerations
The SMC footprint is standard for high-power TVS diodes and provides adequate copper area for heat sinking during repetitive surge events. The part is supplied in Tape & Reel packaging, suitable for automated pick-and-place assembly.
