ON Semiconductor Doubles Number of Diodes and Transistors in SC-75 Package

July 23, 2000 by Jeff Shepard

ON Semiconductor LLC (Phoenix, AZ) announced it has doubled the number of general-purpose diodes and transistors offered in the SC-75 package. The products offered in this package consist of general-purpose single and dual diodes and transistors intended for low-current switching and signal-conditioning applications. The introduction of seven new transistors, identified as BC847BTT1, BC847CTT1, BC857BTTT1, BC857CTT1, MMBT3904TT1, MMBT3906TT1 and MMBT2222ATT1, marks ON Semiconductor's initial offering of general-purpose transistors in this package. The four new diodes, identified as BAS16TT1, DA121TT1, BAV70TT1 and BAW56TT1, add to an existing line of diodes in the SC-75 package.

These general-purpose diodes and transistors in the SC-75 package have been designed to address the recent worldwide increase in demand and production of digital cellular and PCS handsets. The products offer power dissipation up to 360mW for a 1" x 1" pad size.

The SC-75 package, also referred to as the SOT-416, measures 0.9mm in height and requires a 3.15mm square area in board area. The availability of these SC-75 devices offers designers the ability to migrate to a smaller footprint from SOT-23, SC-70 or SOD-123 packages, offering a 60-percent space savings over the SOT-23, and 30 percent over the SC-70.

"Providing a wide range of devices in packages with smaller footprints is critical to the development of lightweight, portable products," said Collette Hunt, general manager of ON Semiconductor's bipolar discretes business unit. "ON Semiconductor is committed to developing additional micropackages to accommodate newer technologies in wireless and hand-held products and in designs with limited board space."

The general-purpose transistors available in the SC-75 package are priced at a resale value of $0.06 per 5,000-unit quantities. The general-purpose single and dual diodes are priced at a resale value of $0.06 and $0.08 each, respectively, per 5,000-unit quantities.
