Motorola Bipolar Power Transistor Device Data

Designer's™ Data Sheet

High Speed, High Gain Bipolar

NPN Power Transistor with

Integrated Collector-Emitter

Diode and Built-in Efficient

Antisaturation Network

The BUL44D2 is state–of–art High Speed High gain BIPolar transistor (H2BIP).

High dynamic characteristics and lot to lot minimum spread (

±150 ns on storage time)

make it ideally suitable for light ballast applications. Therefore, there is no need to

guarantee an hFE window.

Main features:

• Low Base Drive Requirement

• High Peak DC Current Gain (55 Typical) @ IC = 100 mA

• Extremely Low Storage Time Min/Max Guarantees Due to the

H2BIP Structure which Minimizes the Spread

• Integrated Collector–Emitter Free Wheeling Diode

• Fully Characterized and Guaranteed Dynamic VCE(sat)

• “6 Sigma” Process Providing Tight and Reproductible Parameter Spreads

It’s characteristics make it also suitable for PFC application.
