1500 W transient suppressor for 150 V DC rails
The SMCJ150A-13-F: Its 150 V reverse standoff voltage means it sits across a 150 V DC bus without conducting leakage current, then clamps transients at 243 V maximum to protect downstream silicon. The 6.2 A peak pulse current rating at the 10/1000 µs pulse defines the surge the device can absorb before the junction temperature exceeds the safe operating area. For a 150 V rail in an industrial power supply or telecom rectifier, this TVS handles the energy from a lightning-induced surge or inductive load dump without failing short.
The minimum breakdown voltage is 167 V, which guarantees the TVS starts conducting before the rail exceeds that threshold. The DO-214AB (SMC) package has a low thermal resistance to the PCB copper pad — the 1500 W rating assumes a standard footprint with adequate copper area for heat spreading.
