Additional Details

The TPC8123-H is supplied in a small surface-mount package, suitable for automated assembly processes. It is crucial to consult the Toshiba Semiconductor and Storage datasheet for detailed electrical characteristics, thermal performance, and recommended operating conditions. Proper thermal management is essential to ensure reliable operation and prevent damage. The gate-source voltage (VGS) and drain current (ID) should be kept within specified limits. Note that as a P-channel MOSFET, it requires a negative gate-source voltage to turn on.
