The BUD44D2 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
