DEVICE MARKING INFORMATION
See specific marking information in the device marking table on page2 of this data
sheet.
This new series of digital transistors is designed to replace a single
device and its external resistor bias network. The BRT (Bias Resistor
Transistor) contains a single transistor with a monolithic bias network
consisting of two resistors; a series base resistor and a base–emitter
resistor. The BRT eliminates these individual components by integrating
them into a single device. The use of a BRT can reduce both system cost
and board space. The device is housed in the SC–70/SOT–323 package
which is designed for low power surface mount applications.
• Simplifies Circuit Design
• Reduces Board Space
• Reduces Component Count
• The SC–70/SOT–323 package can be soldered using wave or reflow.
The modified gull–winged leads absorb thermal stress during soldering
eliminating the possibility of damage to the die.
• Available in 8 mm embossed tape and reel
Use the Device Number to order the 7 inch/3000 unit reel.
Replace “T1” with “T3” in the Device Number to order
the 13 inch/10,000 unit reel.
