D2PAK Surface Mount Power Package
Motorola Preferred Device
The D2P AK Power Rectifier employs the Schottky Barrier principle in a large
metal–to–silicon power diode. State–of–the–art geometry features epitaxial
construction with oxide passivation and metal overlay contact. Ideally suited for
use in low voltage, high frequency switching power supplies, free wheeling
SCHOTTKY BARRIER
diodes, and polarity protection diodes. These state–of–the–art devices have the
following features:
• Center–Tap Configuration
• Guardring for Stress Protection
• Low Forward Voltage
• 125°C Operating Junction Temperature
• Epoxy Meets UL94, VO at 1/8″
• Guaranteed Reverse Avalanche
• Short Heat Sink Tab Manufactured — Not Sheared!
• Similar in Size to the Industry Standard TO–220 Package
