The peak pulse current it can handle is 103 A under the same 10/1000 µs condition. That current number is the one to check against your expected transient energy — a lower-impedance surge source will push more current through the TVS, and if the surge exceeds 103 A the device may fail shorted. ## Obsolete — sourcing the 1.5SMC10AT3G today For a BOM line that still calls out this exact part number, the only path is independent distribution. We source these against an RFQ — confirmed availability and pricing come back at quote time, not from a live shelf count. ## Package and temperature envelope Housed in a DO-214AB (SMC) surface-mount package, the 1.5SMC10AT3G is a unidirectional device with one protected channel. The junction temperature range is -65°C to 150°C, which covers most industrial and automotive ambient conditions — though the junction temperature during a transient event will spike well above ambient, and the 150°C absolute maximum must not be exceeded. Power line protection is not supported (the part is not designed for continuous AC mains clamping). It is intended for general-purpose transient suppression on DC rails, signal lines, or low-voltage power buses.","metaTitle":"1.5SMC10AT3G Littelfuse Zener TVS, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC10AT3G Zener TVS diode, 1500W peak pulse, 8.55V reverse standoff, DO-214AB SMC.
