Strip packaging means it ships uncut on a tape strip — confirm reel quantities against your assembly line kitting before specifying. Diotec Semiconductor lists this part as Active. For automotive designs with long production runs, this is the status you want — no forced-migration window to manage.","metaTitle":"1.5SMCJ45A-AQ TVS Diode, 45V Standoff, DO-214AB","metaDescription":"Diotec 1.5SMCJ45A-AQ unidirectional Zener TVS, 45V standoff, 72.7V clamping, 1.5kW peak pulse at 10/1000µs, automotive, DO-214AB SMC.
