Description

Product Overview

The MRA4007T3G from onsemi is a surface mount standard recovery power rectifier diode in an SMA (DO-214AC) package. It features a 1000V reverse voltage rating, 1A average rectified forward current, and glass passivated junction construction for enhanced reliability. AEC-Q101 qualified variants (NRVA prefix) are available for automotive applications.

Key Specifications

Package SMA (DO-214AC)

Features

  • Compact SMA package with J-bend leads for automated handling
  • Stable, high-temperature glass passivated junction
  • AEC-Q101 qualified (NRVA prefix versions)
  • Pb-Free and RoHS compliant
  • Low forward voltage drop of 1.1V at 1A
  • High surge current capability of 30A

Applications

  • AC-to-DC rectification in power supplies
  • Reverse polarity protection circuits
  • Free-wheeling diode in inductive load applications
  • Automotive electronics and lighting systems
  • General purpose power rectification

The MRA4007T3G is a surface mount standard recovery power rectifier from onsemi, featuring glass passivated junction construction ideally suited for automotive and industrial power applications. With a 1000V peak repetitive reverse voltage rating and 1A average rectified forward current, this device provides reliable rectification in a compact SMA (DO-214AC) package. The glass passivation ensures stable high-temperature performance and long-term reliability.

The MRA4007T3G operates as a unidirectional current switch based on a PN junction. When forward biased (anode positive relative to cathode), current flows with a forward voltage drop of typically 1.1V at 1A. When reverse biased, the junction blocks current flow up to the rated 1000V reverse voltage, with leakage current specified at 10 µA maximum. The glass passivated junction provides superior temperature stability and reduces reverse leakage compared to standard planar junctions. The standard recovery characteristic (>500ns reverse recovery) makes it suitable for line-frequency rectification applications rather than high-frequency switching.
