Features:

• The STK4102II series (STK4152II) and STK4101Vseries (high-grade type) are pin-compatible in the out-put range of 6W to 50W and enable easy design.
• Small-sized package whose pin assignment is the same as that of the STK4101II series• Built-in muting circuit to cut off various kinds of popnoise
• Greatly reduced heat sink due to substrate temperature 125°C guaranteed
• Excellent cost performance
