It responds to overvoltage events by breaking down at a minimum of 144V and clamping the surge to a maximum of 209V while conducting a peak pulse current of 3A (10/1000µs waveform). This part is a general-purpose protection device for power supplies, industrial controls, and telecom equipment where a single unidirectional clamp is needed across a DC bus. ## 600W peak pulse power — what it buys you For a 130V rail, that 600W translates to the 3A peak current at the 209V clamp point. In practice, this covers the typical surge from inductive load switching or a nearby lightning strike on a 130V bus in an industrial cabinet. If your application expects repetitive surges or higher energy, you would step up to a higher peak pulse power family; for a single-event protection scheme on a moderate-energy rail, the 600W rating is the standard fit. ## Package and mounting — DO-214AA (SMB) The SMBJ130A-TR comes in the DO-214AA (SMB) surface-mount package, a common footprint shared across the SMBJ family. This is a standard catalog part from STMicroelectronics, available through independent distribution channels.","metaTitle":"SMBJ130A-TR TVS Diode, 600W, 130V Standoff, DO-214AA","metaDescription":"STMicroelectronics SMBJ130A-TR is a 600W unidirectional TVS diode with 130V reverse standoff, 209V clamp, 3A peak pulse current.
