Supplied on strip (tape-and-reel or ammo pack), which is standard for high-volume SMT line assembly — no loose bag packaging here; the part ships in the form factor the pick-and-place expects.","metaTitle":"Diotec 1.5SMCJ78 Zener TVS Diode, 1500W Peak, DO-214AB","metaDescription":"Diotec 1.5SMCJ78 unidirectional Zener TVS diode, 78V standoff, 139V clamping, 1500W peak pulse, DO-214AB SMC surface mount.
