? The STK4102II series STK4102II and STK4101V series (high-grade type) are pin-compatible in the out- put range of 6W to 50W. Once the PCB pattern is designed, you can easily satisfy the requirements for new sets simply be changing the IC. ? 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 pop noise ? Greatly reduced heat sink due to substrate temperature 125?C guaranteed ? Excellent cost performanceSTK4141II's datasheet is the same as STK4102II Share this STK4102II pinout picture with your friends or on forums
