With a breakdown voltage range starting at 29.75 V and clamping at 47.99 V (max) at the rated peak pulse current of 33.3 A, this diode absorbs surge energy before it reaches downstream silicon. The SMC footprint is shared by many TVS diodes in the 1500 W class, so a board layout designed for this package can accept pin-to-pin alternatives from other manufacturers — but confirm the standoff voltage and polarity before substituting.","metaTitle":"1.5SMC33 Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC33 Zener TVS diode, 1500W peak pulse power, 28.2V standoff, DO-214AB SMC.
