STD03N and STD03P
Darlington Transistors for Audio Amplifiers
Features and Benefits
▪ Built-in temperature compensation diodes
▪ High power (160 W) handling in a small package
(TO-3P), for minimized heat sink requirements
▪ Built-in drivers and temperature compensation diodes,
reducing external component count and simplifying
circuit design
▪ NPN and PNP versions
▪ Emitter terminals placed symmetrically, pin 5 on NPN
and pin 1 on PNP models, allowing adjacent placement on
PCB to minimize trace length and output skew when used
in pairs
▪ Approved by major manufacturers
Package: 5 pin TO-3P (MT-100)
Description
The STD03N and STD03P are enhanced Darlington transistors
with built-in drivers and temperature compensation diode.
Manufactured using the unique Sanken thin-wafer production
technology, these devices achieve higher power levels through
decreased thermal resistance, and can withstand higher voltages
than similar devices on the market.
The temperature compensation diode is integrated on the same
chip as the power transistors. By this design, the STD03N and
STD03P eliminate delays that would otherwise be induced
between thermal sensing at the heat source, and the operation of
the compensation circuitry. Thus, these transistors are ideal for
applications where enhanced thermal stability is required.
This device is provided in a 5-pin TO-3P plastic package with
pin 4 removed. Contact Allegro® for application support and
additional information on device performance.
Applications include:
▪ General amplifier applications
▪ Public address amplifiers
▪ Car audio amplifiers
