EMBOSSED TAPE AND REEL
SOT-23, SC-59, SC-70/SOT-323, SC–90/SOT–416, SOT-223 and SO-16 packages are available only in
Tape and Reel.
Use the appropriate suffix indicated below to order any of the SOT-23, SC-59,
SC-70/SOT-323, SOT-223 and SO-16 packages. (See Section 6 on Packaging for additional information).
SOT-23:
available in 8 mm Tape and Reel
Use the device title (which already includes the “T1” suffix) to order the 7 inch/3000 unit reel.
Replace the “T1” suffix in the device title with a “T3” suffix to order the 13 inch/10,000 unit reel.

RADIAL TAPE IN FAN FOLD BOX OR REEL
TO-92 packages are available in both bulk shipments and in Radial Tape in Fan Fold Boxes or Reels.
Fan Fold Boxes and Radial Tape Reel are the best methods for capturing devices for automatic insertion in
printed circuit boards.
TO-92:
available in Fan Fold Box
Add an “RLR” suffix and the appropriate Style code* to the device title to order the Fan Fold box.
available in 365 mm Radial Tape Reel
Add an “RLR” suffix and the appropriate Style code* to the device title to order the Radial Tape
Reel.
*Refer to Section 6 on Packaging for Style code characters and additional information on ordering
*requirements.
DEVICE MARKINGS/DATE CODE CHARACTERS
SOT-23, SC-59, SC-70/SOT-323, and the SC–90/SOT–416 packages have a device marking and a date
code etched on the device.
The generic example below depicts both the device marking and a representa-
tion of the date code that appears on the SC-70/SOT-323, SC-59 and SOT-23 packages.
ABC
D
The “D” represents a smaller alpha digit Date Code. The Date Code indicates the actual month in which the
part was manufactured.
