The STK401-020 has four power transistors, so the thermal resistance per transistor
θj-c is 2.1°C / W. With an assured
ambient temperature Ta of 50°C, the required radiator thermal resistance
θc-a would be:
From expression (1)'
θc-a <(125–50)/15.7
<4.78
From expression (2)'
θc-a <(150–50)/15.7–2.1/4
<5.84
To satisfy both, 4.78°C/W is the required radiator thermal resistance.
Figure 2 illustrates Pd - PO when the VCC of STK401-020 is ±16V and RL is functioning at 3.
Pd = 17.6W (1/10 PO max = during 1.5W)
From expression (1)'
θc-a <(125–50)/17.6
<4.26
From expression (2)'
θc-a <(150-50)/17.6–2.1/4
<5.16
To satisfy both, 4.26°C / W is the required radiator thermal resistance. This design example is based on a fixed voltage
supply, and will require verification within your specific set environment.
