Darlington transistors with
built-in temperature compensation diodes
for audio amplifier applications
SAP
series
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.
