Bidirectional TVS clamping at 1.5 kW peak
The 1.5SMC7.5CA_R1_00001: The CA suffix marks this as a bidirectional TVS diode — it clamps both polarities of a transient surge, making it suitable for data lines, power rails, and any node that sees reversible voltage excursions.
Three voltage ratings that define the clamp window
Reverse standoff voltage (typ) is 6.4 V — the device idles below this without conducting, so the protected rail runs at or below 6.4 V under normal conditions. Breakdown voltage minimum is 7.13 V — once the surge pushes the anode above this threshold the TVS avalanches and begins conducting, routing the surge current to ground. Maximum clamping voltage at rated peak pulse current is 11.3 V — this is the voltage the downstream circuit sees during a worst-case 132 A surge event; the protected load must survive 11.3 V briefly without damage.
Where 1.5 kW bidirectional TVS diodes protect circuits
Marked for general-purpose use, this part protects low-voltage power buses, signal interfaces, and control lines against transient overvoltage — anything from a buck converter output to an RS-485 data pair that needs a defined clamp ceiling. Junction temperature rating extends to 150 °C, so the SMC package is adequate for thermally demanding environments as long as the board-level pad and thermal pad layout follow the manufacturer footprint — the cathode tab carries the heat out of the junction.
Sourcing — active production, quoted to order
Surface-mount DO-214AB supplied on tape-and-reel or cut-tape; the tape option suits high-volume pick-and-place lines while cut-tape works for prototyping and rework bays.
