At 1.5 kW peak pulse, the 356V clamping ceiling is the voltage present at the protected node during the event — downstream silicon sees that spike width, not the raw transient. Selecting a standoff with adequate headroom above the nominal rail (for example a 24 V rail uses a standoff in the 27–33 V range; this part targets 220 V nominal rails) is the primary sizing decision for any TVS in a protection chain. ## Package and thermal integration The DO-214AB (SMC) package is the standard foot-print for 1.5–3 kW TVS diodes across multiple manufacturers — the cathode bar in the centre divides the package lengthwise and carries the thermal path to the board pad. Junction temperature is calculated from ambient plus the Ipp × Vc product multiplied by the board-level thermal resistance; the board pad under the cathode bar is the primary heatsinking path for a surface-mount TVS, so the footprint pad should not be undersized even in a space-constrained layout. ## Sourcing posture and lifecycle Panjit lists the part as Active — it is a current-production line item available through independent distribution. Confirm the datasheet clamping curve and peak pulse waveform before substituting — 10/1000 µs is the defining surge shape for this power class.
