Overview
This datasheet provides extensive information on high-speed stud base rectifiers rated up to 30.0 amperes, specializing in military applications where high voltage and speed are essential. These rectifiers are designed for use in switching power supplies and regulators. They stand out due to their hermetic seal, metallurgical bonding, and capability to function at high temperatures.
Key Features
- Hermetic Seal
- Metallurgically Bonded
- High Temperature Operation
Absolute Maximum Ratings
The rectifiers can operate at a junction operating temperature range from -85°C to +150°C. For storage, the temperature extends up to +175°C, ensuring they can withstand extreme conditions without degradation.
Performance Characteristics
Maximum Current Rating
The 1N3909/73909 Series has a diverse temperature-dependent maximum current rating, highlighting the device’s adaptability to various thermal conditions.
Maximum Allowable Surge Current
The rectifiers are capable of managing different levels of surge current, with a direct correlation between the number of cycles at 60Hz and the maximum allowable surge current.
Typical Reverse Current vs. Instantaneous Forward Voltage
Charts detailing the typical reverse current across various temperatures and the relationship between the instantaneous forward voltage and current are provided.
Product Variants and Specifications
There are several models of the rectifiers categorized by case type and type number, differing by their peak inverse voltage (PIV), current ampere rating at 25°C, and cases type ratings. The document also specifies the forward surge current (IFsm) for each type.
Military Specifications
Selected products are available that meet military specifications, indicated by designations such as JAN, JTX, and JTXV, adhering to MIL-S-19500/304C and MIL-S-19500/308 standards.
