The 1N5408G-T is a glass passivated rectifier diode manufactured by Diodes Incorporated. It features a DO-201AD axial through-hole package and supports an average rectified output current of 3.0 A at 55°C ambient temperature. The device withstands a peak repetitive reverse voltage of 1000 V with a maximum forward voltage drop of 1.1 V at 3.0 A. It exhibits a typical reverse recovery time of 2.0 μs and handles a non-repetitive peak forward surge current of 125 A. Operating temperatures range from -65°C to +150°C.
Verify the specific ordering suffix 'T' corresponds to the 1.2K Tape & Reel packaging configuration as defined in the manufacturer's ordering information table. Confirm that the component meets the required environmental standards, specifically RoHS compliance and UL flammability rating 94V-0 for the molded plastic case material before finalizing procurement specifications.
Select this component when a standard recovery rectifier with a 1000 V blocking voltage and 3 A continuous current rating is required. Ensure the application environment allows for the specified thermal resistance characteristics and that the operating temperature falls within the -65°C to +150°C junction range. Verify that the DO-201AD package dimensions fit the intended PCB layout constraints.
This part belongs to the 1N5400G–1N5408G series of 3.0A glass passivated rectifiers. The 'G' suffix indicates RoHS compliance, while the '-T' suffix designates the tape and reel shipping format. The series utilizes a single-phase, half-wave configuration suitable for general-purpose industrial and commercial electronics requiring reliable DC conversion.
Compatible substitutes include the 1N5408G (bulk packaging) or equivalent 3A 1000V rectifiers from other manufacturers such as SMC Diode Solutions or Vishay, provided they match the DO-201AD footprint and electrical ratings.
