transistors with built-in temperature compensation diodes for audio amplifier applications

Features
qBuilt-in temperature compensation diodes and one emitter resistor qReal time temperature compensation The temperature compensation diodes are mounted on one chip and placed in the center of the chip to detect temperature rises directly. qElimination of the temperature dependency of the idling current The temperature coefficient of the diodes is optimized to have the idling current stabilized; thus one of the fatal failure modes in conventional Darlington
transistors, Thermal Runaway, is avoidable. qSymmetrical design for the
PNP and the
NPN pinouts The new design minimizes the length of the pattern layout, and output distortions are controlled. qDarlington
transistors, temperature compensation diodes and one emitter resistor are incorporated in one package, so labor for parts insertion as well as the parts count is reduced.
