VOLTAGE/HIGH SPEED
D44TD Series
NPN POWER TRANSISTORS
300-400 VOLTS
2 AMP, 500 WATTS
The D44TD series of NPN Power Transistors is designed for use in switching applications requiring high-
voltage capability, fast switching speeds and low-saturation
voltages.
They are particularly suited for off-line switching power supplies, solid-state lighting ballast, invertes, solenoid/relay drivers and deflection circuits.
Features: • Performance information tailored for switching
applications • 100°C maximum limits specified for:
• Switching times • Saturation
voltages • Leakage currents • 300 to 400V VCEO(sus) in a TO-220AB Package
• Very fast turn-qff, tf 180 nsec (typ.
) @ 1.
