The SMB package is widely used for 600W-class TVS diodes and mates with common reflow profiles for lead-free assembly. Operating from -55°C to 150°C junction temperature, the device covers the full industrial temperature range and maintains clamping performance across thermal extremes without derating the peak pulse power at ambient temperatures below 25°C. ## Active lifecycle and procurement posture The part is offered in Tape & Reel (TR) or Cut Tape (CT) packaging to match assembly volume requirements.","metaTitle":"SMBJ18A-13 Diodes Inc TVS, 600W, 29.2V Clamp, DO-214AA","metaDescription":"SMBJ18A-13 Diodes Inc Zener TVS diode: 18V standoff, 29.2V clamp at 20.5A, 600W peak pulse, DO-214AA SMB.
