2SD1555,NPN Power Transistor with Built-in Damper Diode, TO-3P(H)IS

The 2SD1555 is a silicon NPN power transistor designed for high-voltage and high-speed switching applications, particularly in color television horizontal deflection circuits. It features a high collector-base voltage of 1500V and a collector-emitter voltage of 600V, making it suitable for demanding applications. The built-in damper diode enhances performance by suppressing voltage spikes during switching operations. With a low collector-emitter saturation voltage ranging from 3.0V to 5.0V at I_C = 4A and I_B = 0.8A, the 2SD1555 ensures efficient performance. It is capable of dissipating up to 50W of power and is encased in a robust TO-3P(H)IS package, providing durability and reliability in various operating conditions.
