BU2510-E3/45 Description

Short technical summary and product information.

The BU2510-E3/45 is a single-phase bridge rectifier from Vishay General Semiconductor, part of the Enhanced isoCink+™ series. It is designed for AC/DC full-wave rectification in power supply and white-goods applications. The device features a glass passivated chip junction for reliability. Key electrical ratings include a repetitive peak reverse voltage (VRRM) of 1000V, an average rectified forward current of 25A when mounted with a heatsink (TC=60°C), and 3.5A without heatsink (TA=25°C). The non-repetitive peak forward surge current (IFSM) is 300A. Forward voltage is typically 0.97V at 12.5A and 25°C. Reverse leakage current is 5µA maximum at 25°C. The device is housed in a through-hole BU package with matte tin plated leads, solderable per J-STD-002 and JESD 22-B102. The molding compound meets UL 94 V-0 flammability rating. Operating junction temperature range is -55°C to +150°C. The E3 suffix indicates RoHS-compliant and lead-free commercial grade. This rectifier is suitable for general purpose use in switching power supplies, home appliances, and white goods.
