1500W bidirectional TVS in DO-214AB
The 1.5SMC200CA R7G: With a peak pulse power rating of 1500 W (10/1000 µs waveform) and a clamping voltage of 274 V at 5.7 A peak pulse current, this part handles moderate-energy surges — think inductive kickback from relays or ESD events on industrial I/O lines. The single bidirectional channel means you can place it across a differential pair or an AC-coupled line without worrying about polarity — one device covers both halves of the waveform.
Breakdown and clamping — what the numbers mean on the bench
Minimum breakdown voltage is 190 V; the TVS starts conducting at that threshold and clamps the transient to 274 V maximum before the current reaches 5.7 A.
Package and board-fit
Housed in a DO-214AB (SMC) surface-mount package, the same footprint as standard SMC diodes — reflow profile follows typical Pb-free solder curves for the body size. Supplied on Tape & Reel (TR), suitable for automated pick-and-place assembly.
