The -55°C to 150°C junction temperature range covers both cold-start telecom cabinets and hot industrial enclosures without derating concern at the ambient extremes. ## Package and board-fit — DO-214AA SMB footprint Housed in the DO-214AA (SMB) package, the SMBJ170A-13 shares the same 2-lead footprint as the rest of the SMBJ family. The SMB package is larger than the SMA variant, offering better thermal dissipation for the 600W pulse — the copper pad area under the cathode tab on the PCB sets the junction-to-ambient thermal resistance for repetitive surges. Tape & Reel packaging supports automated pick-and-place for volume production. ## Active production and sourcing posture The part carries no power line protection rating — it is intended for signal and DC rail transient suppression, not AC mains clamping.","metaTitle":"SMBJ170A-13 TVS Diode, 170V Standoff, 275V Clamp, DO-214AA","metaDescription":"SMBJ170A-13 unidirectional TVS from Diodes Inc. 170V reverse standoff, 275V clamp at 2.2A, 600W peak pulse power.
