Overview:
The datasheet provides detailed information about a series of hermetically sealed, high-efficiency, center-tap rectifiers designed for use in power switching applications. These devices are made to operate effectively at frequencies exceeding 100 kHz and are suited for high-reliability (Hi-Rel) uses due to their small size and robust packaging.
Key Features:
Performance: The rectifiers have a very low forward voltage and a very fast switching time, ranging from 35 to 50 nanoseconds (ns). The package offers low thermal resistance, high surge capability, and is isolated.
Hermetic Packaging: Utilizing the JEDEC TO-258AA metal package, the rectifiers provide a robust and sealed containment, which is critical for reliability in harsh environments.
Variety: Available with common cathode configuration by default, these rectifiers can also be obtained with common anode or doubler configurations upon request.
Industry Compliance: These components have been screened to the military specification MIL-S-19500 with TX, TXV, and S level ratings.
Specifications:
The rectifiers support a peak inverse voltage range from 50 to 600 volts, with a maximum average direct current (DC) output current at a case temperature of 100°C standing at 15 amperes. They are also capable of handling a non-repetitive sinusoidal surge current of up to 150 amperes for an 8.3-millisecond duration. Their operating and storage temperature range lies between -55°C and +150°C, accommodating extreme conditions.
Electrical Characteristics:
The datasheet lists several types of rectifiers (OM5204xX to OM5235XX), with peak inverse voltages (PIV) ranging from 50 to 600 volts. It provides maximum forward voltage at different temperatures and current levels, with values such as 1.1 V at 15 A and 0.90 V at 15 A for lower voltage variants. It also details maximum reverse current and thermal resistance, and recovery time, indicating efficient thermal management and rapid switching capabilities that are important in high-frequency applications.
