1ch class-AB Audio Power IC
60W
Overview
The STK404-070N-E is a hybrid IC for the audio power amplifier that mounts discrete components as the audio
power amplifier circuit in small space using the original Insulated Metal Substrate Technology IMST. The compact
package has been achieved by adopting the low thermal resistance substrate (our conventional model kind ratio).
Application
Audio Power use
Features
Pin-to-pin compatible outputs ranging from 60W to 180W
Miniature package
Output load impedance: R = 6 recommended.
L
Allowable load shorted time: 0.3 second
Allows the use of predesigned applications for standby, mute, and the load short protection circuit.

A Thermal Design Tip For STK404-070N-E Amplifier
[Thermal Design Conditions]
The thermal resistance (θc-a) of the heat-sink which manages the heat dissipation inside the Hybrid IC will be
determined as follow:
(Condition 1) The case temperature (Tc) of the Hybrid IC should not exceed 125°C
Pd c-a + Ta 125°C··································································· (1)
Where Ta : the ambient temperature for the system
(Condition 2) The junction temperature of each power transistor should not exceed 150°C
Pd c-a + Pd/N j-c + Ta 150°C·················································· (2)
Where N : the number of transistors (two for 1 channel , ten for channel)
θj-c : the thermal resistance of each transistor (see specification)
Note that the power consumption of each power transistor is assumed to be equal to the total power dissipation (Pd)
divided by the number of transistors (N).
From the formula (1) and (2), we will obtain:
c-a (125 Ta)/Pd ······································································ (1)’
c-a (150 Ta)/Pd j-c/N ··························································· (2)’
The value which satisfies above formula (1)’ and (2)’ will be the thermal resistance for a desired heat-sink.
Note that all of the component except power transistors employed in the Hybrid IC comply with above conditions.
[Example of Thermal Design]
Generally, the power consumption of actual music signals are being estimated by the continuous signal of
1/8 P max. (Note that the value of 1/8 P max may be varied from the country to country.)
O
O
(Sample of STK404-070N-E ; 40W×1ch)
If V
is ±30V, and R is 6, then the total power dissipation (Pd) of inside Hybrid IC is as follow;
L
CC
Pd = 19.6W (at 5W output power,1/8 of P max)
O
There are two (2) transistors in Audio Section of this Hybrid IC, and thermal resistance (θj-c) of each transistor is
3.0°C/W. If the ambient temperature (Ta) is guaranteed for 50°C, then the thermal resistance (θc-a) of a desired heat-
sink should be;
From (1)’ c-a (125 50)/19.6
3.83
From (2)’ c-a (150 50)/19.6 3.0/2
3.60
Therefore, in order to satisfy both (1)’ and (2)’, the thermal resistance of a desired Heat-sink will be 3.60°C/W.
[Note]
Above are reference only. The samples are operated with a constant power supply. Please verify the conditions when
your system is actually implemented.
