Rated for 1500W (1.5kW) peak pulse power, this part handles surge events common in industrial power supplies, telecom rectifiers, and AC-DC converter outputs where the DC bus sits near 145V. ## Breakdown and clamping — the protection window The minimum breakdown voltage is 161.5V, so the device starts conducting before the voltage reaches a level that would damage downstream silicon rated for a 200V to 250V absolute maximum. The 234V clamping ceiling ensures the protected node sees a peak voltage well within the typical 250V to 300V MOSFET or IGBT breakdown margin on a 145V bus. Bidirectional construction means a single DO-214AB part replaces two series-back-to-back unidirectional TVS diodes — saves board area and one solder joint per protected line. Operating temperature spans -65°C to 150°C junction, covering the full industrial and automotive ambient range without derating concerns at the board level.","metaTitle":"1.5SMC170CA TR13 PBFREE TVS, 1500W, 145V Standoff, DO-214AB","metaDescription":"Central Semiconductor 1.5SMC170CA TR13 PBFREE bidirectional TVS, 1500W peak pulse, 145V reverse standoff, DO-214AB (SMC).
