No official successor order code is recorded in the lifecycle data, meaning the manufacturer no longer produces this exact part and has not designated a drop-in replacement. The DO-214AB (SMC) package is a surface-mount, JEDEC-standard outline with a gull-wing lead form. The cathode band identifies the unidirectional orientation; the anode is the tab side. Reflow profile follows standard lead-free solder profiles for the tin-plated terminations.","metaTitle":"1.5SMC16AT3G Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC16AT3G Zener TVS, 1500W peak pulse, 15.2V breakdown, 22.5V clamp, DO-214AB.
