The 64.4 V minimum breakdown voltage gives a guard band above the 58 V standoff, so the part stays out of conduction during normal operation and only fires when a transient pushes past the threshold. ## Temperature range and package — where it fits No power-line protection claim (the part is not designed for AC mains), but for DC rails up to 58 V it is a straightforward clamp.","metaTitle":"STMicroelectronics SMBJ58A-TR TVS Diode, 600W, DO-214AA","metaDescription":"STMicroelectronics SMBJ58A-TR TRANSIL™ TVS diode, 58V standoff, 600W peak pulse power, unidirectional, DO-214AA SMB, -55°C to 150°C.
