DFB2505 - DFB25100

Glass Passivated Bridge Rectifiers

Features

• UL certificate # E326243

• Glass passivated junction

• Ideal for printed circuit board

• Reliable low cost construction

• Plastic material has Underwriters Laboratory Flammability Classification 94V-0

• Surge overload rating to 350 amperes peak

• Isolated voltage from case to lead over 2500 volts

* Single phase, half wave, 60Hz, resistive or inductive load. For capacitive load, derate current by 20%

** Device mounted on 4" x 6" x 0.25" Al-plate heat sink.

*** In development. Please contact Fairchild Semiconductor for more information.

* Measured at 1MHz and applied Reverse bias of 4.0V DC.
