The SMA47XXA Series are surface mount Zener diodes featuring a low profile package, ideal for automated placement. They utilize a glass-passivated chip junction for high forward surge capability and meet MSL level 1, per J-STD-020, with a maximum peak of 260 C. The molding compound meets UL 94 V-0 flammability rating and is RoHS-compliant and halogen-free. Terminals are tin-plated and solderable per J-STD-002 and JESD22-B102. The cathode line denotes the cathode end.
