Bias Resistor Transistors LDTA114EET1G Series
PNP Silicon Surface Mount Transistors S-LDTA114EET1G Series
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 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-89 package which is designed for low power surface mount applications.
• Simplifies Circuit Design • Reduces Board Space • Reduces Component Count • The SC-89 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. • We declare that the material of product compliance with RoHS requirements. • S- Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q101 Qualified and PPAP Capable.
