The MRA4003T3 series is a surface mount standard recovery power rectifier with glass passivation. It is ideally suited for surface mount automotive applications. The compact J-Bend leads package is ideal for automated handling. The rectifier has a stable, high temperature, glass passivated junction. The case is molded epoxy that meets UL 94 V-0 standards and weighs approximately 70 mg. All external surfaces are corrosion resistant and the terminal leads are readily solderable. The lead and mounting surface temperature for soldering purposes is 260°C maximum for 10 seconds in a solder bath. The rectifier has a band in the plastic body to indicate the cathode lead. The ordering information includes various package options and quantities. Maximum ratings information is not provided in the document.
This handbook describes the MRA4003T3 series recovery power rectifiers, which are surface‑mount devices in an SMA plastic package. It includes construction features, mechanical characteristics, ordering information, and maximum electrical ratings.
The document also contains thermal and electrical characteristic tables, package dimensions, and contact information for literature fulfillment and technical support.
