American Microsemiconductor TF200-700 Power Transistor

The TF200-700 power transistor from American Microsemiconductor is a low-frequency, NPN bipolar transistor designed for discrete power applications. This device targets applications where a robust, analog-friendly transistor is needed for power amplification or regulation in circuits that operate at relatively slow switching speeds. The NPN structure provides typical emitter-collector current paths suited to linear amplification, regulator circuits, and other non-rapid switching roles in power electronics. In practice, designers rely on this class of device for simple, rugged amplification or regulation tasks within single-transistor power meshes, where the device's characteristics support stable operation with appropriate heat sinking and bias networks. When incorporating the TF200-700 into a circuit, engineers consult the official datasheet to verify electrical ratings, such as collector current and voltage limits, as well as package details, pinout, thermal resistance, and mounting recommendations to ensure reliable thermal management. The TF200-700's identification under the American Microsemiconductor portfolio signals a purpose-built, discrete NPN power transistor intended for applications that require a sturdy, straightforward solution in low-frequency power paths.
