DF01MA-E3/45

DF01MA-E3/45 is a miniature glass-passivated single-phase bridge rectifier from Vishay General Semiconductor. It is designed for AC-to-DC full-wave rectification in general purpose applications. The device provides a repetitive peak reverse voltage of 100 V, a maximum RMS reverse voltage of 70 V, and a maximum DC blocking voltage of 100 V. It can deliver an average forward current of 1.0 A at an ambient temperature of 40°C, with a peak forward surge current rating of 30 A for a single sine-wave pulse.

The rectifier has a maximum forward voltage of 1.1 V at 1.0 A forward current, and reverse current is 5 µA at 25°C and 500 µA at 125°C. Typical junction capacitance is 25 pF at 4 V. The device is rated for operating junction and storage temperatures from -55°C to +150°C. Thermal resistance is 40°C/W junction-to-ambient and 15°C/W junction-to-lead when mounted on a PCB with 0.5" x 0.5" copper pads.

The part is supplied in a 4-lead DFM through-hole package with matte tin plated solderable leads. It is RoHS3-compliant, carries UL recognition (file E54214), and the molding compound meets UL 94 V-0 flammability rating. Typical applications include power supplies, lighting ballasts, adapters, battery chargers, home appliances, office equipment, and telecommunications.
