It is primarily used in high-power switching applications like motor control, SMPS circuits, welding machines, and power inverters.

It requires an external heatsink and thermal paste for effective dissipation, especially in continuous or high-current operations.

Depending on the application, modern MOSFETs or IGBTs can be more efficient alternatives, but the replacement requires careful redesign to match characteristics.

It's available through select suppliers or as legacy inventory. Check verified distributors or reach out to Toshiba for current availability.

Yes, base current must be controlled via an appropriate resistor to avoid damage and ensure proper saturation during switching.
