1500W bidirectional transient suppressor
The 1.5SMC200CA TR13 PBFREE: This is a single-channel bidirectional device in the DO-214AB (SMC) surface-mount package. The bidirectional configuration means a single part handles both positive and negative transients, saving board space versus back-to-back unidirectional diodes.
Voltage ratings and the clamping decision
The breakdown voltage range starts at 190V minimum — this is where the device begins to avalanche. For a 150V to 170V DC bus — common in three-phase rectified mains or telecom rectifiers — the 171V standoff gives margin below the nominal rail while clamping well before the downstream components' absolute maximum ratings.
Package and board integration
Housed in the DO-214AB (SMC) package, this TVS has a standard JEDEC footprint with the cathode tab as the heat path. The surface-mount SMC footprint is shared across the 1.5SMC family, so a single PCB layout covers multiple voltage variants if the BOM needs to flex.
