STD02N and STD02P
Darlington Transistors for Audio Amplifiers
Features and Benefits
Description
▪ Built-in temperature compensation diodes
▪ High power (130 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
TheSTD02NandSTD02PareenhancedDarlingtontransistors
with built-in drivers and temperature compensation diode.
Manufactured using the unique Sanken thin-wafer production
technology, these devices achieve higher power levels through
decreasedthermalresistance,andcanwithstandhighervoltages
than similar devices on the market.
▪ NPN and PNP versions
The temperature compensation diode is integrated on the same
chip as the power transistors. By this design, the STD02N and
STD02P eliminate delays that would otherwise be induced
betweenthermalsensingattheheatsource,andtheoperationof
the compensation circuitry.Thus, these transistors are ideal for
applications where enhanced thermal stability is required.
▪ 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
This device is provided in a 5-pin TO-3P plastic package with
pin 4 removed. Contact Sanken™ for application support and
additional information on device performance.
Package: 5 pin TO-3P (MT-100)
Applications include:
▪ General amplifier applications
▪ Professional audio amplifiers
▪ Car audio amplifiers
