NPN Bipolar Power Transistor

For Switching Power Supply Applications

The BUL44/BUL44F have an applications specific state鈥搊f鈥搕he鈥揳rt die designed

for use in 220 V line operated Switchmode Power supplies and electronic light

ballasts. These high voltage/high speed transistors offer the following:

鈥?/div>

Improved Efficiency Due to Low Base Drive Requirements:

鈥?High and Flat DC Current Gain hFE

鈥?Fast Switching

鈥?No Coil Required in Base Circuit for Turn鈥揙ff (No Current Tail)

鈥?/div>

Full Characterization at 125擄C

鈥?/div>

Tight Parametric Distributions are Consistent Lot鈥搕o鈥揕ot

鈥?/div>

Two Package Choices: Standard TO鈥?20 or Isolated TO鈥?20
