DESCRIPTION

The PMLL4148L and PMLL4448 are high-speed switching diodes fabricated in

planar technology, and encapsulated in small hermetically sealed glass

SOD80C SMD packages. PMLL4148L was formerly named PMLL4148 and

has no difference to this type in technical specification, processing, packing or

labelling.
