BUD42D
High Speed, High Gain
Bipolar NPN Transistor with
Antisaturation Network and
Transient Voltage
Suppression Capability
The BUD42D is a state−of−the−art bipolar transistor. Tight dynamic
characteristics and lot to lot minimum spread make it ideally suitable
for light ballast applications.
Main Features:
• Free Wheeling Diode Built In
• Flat DC Current Gain
• Fast Switching Times and Tight Distribution
• “6 Sigma” Process Providing Tight and Reproducible Parameter
Spreads
• Epoxy Meets UL94, VO @ 1/8”
• ESD Ratings: Machine Model, C; >400 V
Human Body Model, 3B; >8000 V
Two Versions:
• BUD42D−1: Case 369D for Insertion Mode
• BUD42D, BUD42DT4: Case 369C for Surface Mount Mode
