Tape & Reel and Packaging Specifications for
Small-Signal Transistors, FETs and Diodes
Embossed Tape and Reel is used to facilitate automatic pick and place equipment feed requirements. The tape is used as the
shipping container for various products and requires a minimum of handling. The antistatic/conductive tape provides a secure
cavity for the product when sealed with the “peel–back” cover tape.
• Two Reel Sizes Available (7"and 13",)
• SOT–23, SC–70/SOT–323,
• Used for Automatic Pick and Place Feed Systems
SC–89, SC–88/SOT–363, SC–88A/SOT–353,
• Minimizes Product Handling
SOD–323, SOD-523 in 8 mm Tape
• EIA 481, –1, –2
Use the standard device title and add the required suffix as listed in the option table below (Table 1). Note that the individual
reels have a finite number of devices depending on the type of product contained in the tape. Also note the minimum lot size is
one full reel for each line item, and orders are required to be in increments of the single reel quantity.
