PNP Silicon Surface Mount Transistor
with Monolithic Bias Resistor Network
This new series of digital transistors is designed to replace a single
device and its external resistor bias network. The Bias Resistor
Transistor (BRT) 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.
Features
• Pb−Free Packages are Available
• 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.
Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
