The MRA4005T3G is a general-purpose single rectifier diode manufactured by onsemi (formerly AMI Semiconductor), designed to provide reliable power conversion in a compact surface-mount package. This discrete semiconductor component falls within the diodes-rectifiers-single category and is engineered to address common design challenges including space constraints on PCBs, thermal management requirements, and the need for dependable rectification in medium-voltage applications.
This device features a maximum DC reverse voltage rating of 600V and handles an average rectified current of 1A, making it suitable for various power supply and voltage regulation tasks. The diode exhibits a maximum forward voltage drop of 1.1V at 1A current, which represents a reasonable trade-off between efficiency and performance for standard recovery applications. With a reverse leakage current of just 10µA at 600V, it maintains excellent blocking characteristics when reverse-biased. The component utilizes standard recovery technology with switching speeds greater than 500ns at currents above 200mA, appropriate for line-frequency rectification and general-purpose switching applications.
Housed in a DO-214AC SMA (Surface Mount Assembly) package, this RoHS3-compliant component is designed for surface-mount installation, facilitating automated assembly processes and enabling high-density circuit layouts. The operating junction temperature range spans from -55°C to 175°C, ensuring reliable performance across demanding environmental conditions from extreme cold to high-temperature industrial environments.
The primary advantages of this rectifier include its compact footprint for space-efficient designs, robust voltage handling capability for medium-voltage circuits, low leakage current for improved efficiency during blocking states, and wide temperature tolerance for diverse operating environments. It's supplied in tape and reel packaging with quantities of 820,100 units, making it ideal for high-volume manufacturing operations.
This diode finds application in AC-to-DC power supplies, battery charging circuits, voltage regulation modules, industrial control systems, consumer electronics, automotive electronics, and general rectification tasks where standard recovery speeds are acceptable.
Equivalent and alternative models include the 1N4005 series in through-hole packages, the S1G through S1M series from various manufacturers offering similar ratings in SMA packages, Vishay's VS-1EGP60 series, Diodes Incorporated's S1A-S1M family, and Fairchild/onsemi's RS1A-RS1M series, all providing comparable 600V, 1A rectification capabilities with standard recovery characteristics.
