The strip packaging option confirms unit-per-pack dispatch, not full reel; reel quantities and full-reel MOQs are confirmed at quote time. The 'AQ' automotive suffix on this Diotec part aligns with automotive procurement practice, though the evidence does not confirm a specific AEC-Q qualification class. For AEC-Q100 or AEC-Q101 screen classes required by some OEM screening programs, the component engineer should confirm the exact lot qualification level with Diotec directly — particularly the temperature cycling and humidity bias screening records. ## Sourcing posture — active production, independent distribution Diotec Semiconductor lists the 1.5SMCJ28CA-AQ as Active — this is a current-production part suitable for new automotive designs, not a last-time-buy candidate. The Diotec brand maintains independent distribution supply, and this part is quoted to order against BOM quantity with availability and lead time confirmed at RFQ.","metaTitle":"Diotec 1.5SMCJ28CA-AQ TVS Diode, 28V standoff","metaDescription":"Diotec 1.5SMCJ28CA-AQ bidirectional TVS diode, 28V standoff, 31.1V min breakdown, 1.5 kW peak pulse, AEC automotive.
