1500 W peak pulse in a DO-214AB footprint
The 1.5SMC170AHM3_A/I: It clamps a 145 V reverse standoff voltage to a maximum of 234 V at a peak pulse current of 6.4 A.
Voltage clamping and application fit
With a 145 V reverse standoff voltage (working voltage), this TVS sits on a 145 V nominal rail and remains transparent until a transient pushes it above the 162 V minimum breakdown threshold. The 234 V maximum clamping voltage defines the peak voltage the downstream circuitry must survive during a 6.4 A pulse. The 1500 W peak pulse rating (10/1000 µs) is the standard TVS power metric — it translates to the device's ability to absorb a defined surge without failing. For shorter transients (e.g., 8/20 µs), the peak power capability is significantly higher, but the 10/1000 µs figure is the one used for cross-reference and derating calculations. It is suited for 145 V bus protection in automotive and telecom equipment where the board sees the full temperature range.
