Overview
The LITE-ON Semiconductor datasheet provides detailed information on glass passivated bridge rectifiers, specifically the GBJ2504 thru GBJ2510 models. These devices are designed for converting alternating current (AC) to direct current (DC) and are suitable for printed circuit boards due to their compact design.
Key Features
The bridge rectifiers have a reverse voltage range from 400 to 1000 volts and a forward current capability of 25 amperes. They are recognized for their low forward voltage drop and high current capability. Additional features include UL recognition (file # E95060), compliance with RoHS 2002/95/EC, and a flammability classification of 94V-0. Each rectifier weighs approximately 6.82 grams.
Maximum Ratings and Electrical Characteristics
These devices operate optimally at an ambient temperature of 25°C. They have different maximum repetitive peak reverse voltages (VRRM) and maximum DC blocking voltages (VDC) depending on the model number (400V for GBJ2504, 600V for GBJ2506, 800V for GBJ2508, and 1000V for GBJ2510). The average rectified output current per device with a heatsink is 25 amperes, with a peak forward surge current of 350 amperes for an 8.3ms single half sine-wave at 25°C. The recommended mounting torque is 0.5 N.m, and the operating and storage temperature range is from -55°C to +150°C.
Electrical Characteristics
The datasheet also provides static electrical characteristics, including forward voltage and leakage current at different temperatures (25°C and 125°C), as well as typical junction capacitance measured at 0 MHz with a 4.0V reverse voltage applied.
Thermal Characteristics
The thermal characteristics offer a typical thermal resistance from the junction to case, lead, and ambient (RthJc, RthJL, RthJA) when mounted on a specified aluminum plate heatsink dimensions.
Performance Curves
Included as well are rating and characteristic curves that depict forward current derating, maximum non-repetitive surge current, typical forward characteristics, typical junction capacitance, and typical reverse characteristics under various test conditions.
Conclusion
This datasheet provides electrical engineers and designers with essential information for integrating the GBJ2504 to GBJ2510 series bridge rectifiers into their applications, ensuring efficient conversion from AC to DC power with dependable performance within stated environmental and operational parameters.
