Zener TVS, 1.5SMC series, 1.5SMC600A, 512 V standoff, 828 V clamping, 1.9 A peak pulse, 1500 W, DO-214AB SMC package, surface mount.","salesMarkdown":"The 1.5SMC600A is a unidirectional Zener-based TVS diode in the DO-214AB (SMCJ) package, rated 1500 W peak pulse at the standard 10/1000 µs waveform — this is the surge-energy ceiling the Littelfuse 1.5SMC series is built around for telecom and access-equipment line cards. The standoff voltage of 512 V defines the normal operating rail this diode sits across without conduction — the protected line runs at or below 512 V DC in typical telecom power-bus or DSL over-current architectures. When a surge exceeds the 570 V minimum breakdown, the device clamps at 828 V maximum and conducts the 1.9 A peak pulse current away from the load — the 258 V margin between standoff and clamping ceiling is the TVS safety window. ## Telecom deployment context and junction thermal margin Listed applications flag telecom — power-overEthernet cards, DSLAM line modules, and central-office DC rails at 48 V or 60 V where transients on the distribution bus need a defined clamping shelf below semiconductor withstand limits. Surface-mount termination in the DO-214AB package routes the fault current to the PCB plane through the solder joints — board layout must carry the peak pulse current without the trace fusing open before the TVS clamps.","metaTitle":"1.5SMC600A TVS Diode, 1.5kW, 512V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC600A unidirectional TVS Zener, 512 V standoff, 828 V clamping, 1.5 kW peak pulse.
