Overview
The datasheet details the Military Fast Recovery Rectifiers models 1N3909A through 1N3913A by Microsemi, which are part of the DO2OJAB (DO5) package series. These components are designed to operate with a junction temperature of 150°C and offer a repetitive peak reverse voltage range from 50V to 400V. The rectifiers have an average forward current of 50 Amps and are characterized by their fast recovery time, with options for standard or reverse polarity.
Electrical Characteristics
Key electrical properties include:
Average forward current (IF(AV)): 50 Amps
Maximum surge current (FSM): 400 Amps
Max peak forward voltage (VFM): 2.75 Volts and 1.40 Volts at specified conditions
Maximum peak reverse current (RM): 6 mA to 15 mA
Maximum reverse recovery time (tRR): 150 ns
Maximum junction capacitance (CJ): 150 pF
Thermal and Mechanical Characteristics
The datasheet details temperature ranges for storage (TSTG from 65°C to 175°C) and operation (TJ from 65°C to 150°C). It also specifies the maximum thermal resistance from junction to case (RθJc) as 0.8°C/W and provides mechanical specifications such as mounting torque and weight.
Additional Features
The rectifiers come with 1/4-28 UNF-3A threads, ensuring full threading within a precise distance. They are available in JAN, JANTX, and JANTXV quality levels conforming to Mil-PRF-19500/308A standards. Pulse test conditions are clarified, specifying a pulse width of 300 µs and a duty cycle of 2% to ascertain the parameters accurately.
Ordering Information
When ordering, the datasheet mentions the addition of the suffix ‘R’ for reverse polarity models. This provides flexibility for different circuit designs and ensures correct implementation as per application requirements.
