MBRB2060CTG Electrical and Thermal Specifications

Understanding the electrical and thermal performance parameters is essential for optimal deployment in power conversion circuits. The MBRB2060CTG is rated for:

Maximum reverse voltage (VRRM): 60 V

Average forward current: 20 A (10 A per diode in common cathode array)

Low typical forward voltage at given currents, reducing conduction losses

Fast switching characteristics inherent to the Schottky structure, enabling efficient high-frequency operation

Robust ESD ratings: Machine Model > 400 V, Human Body Model > 8000 V

Thermally, the device supports high junction temperatures, with effective heat transfer achieved via the surface-mount pad in D2PAK format. When mounted on an FR-4 PCB with recommended pad sizes, the rectifier maintains integrity under rigorous operational stresses, provided the thermal dissipation (dPD/dTJ) stays within the specified junction-to-ambient resistance.

From a mechanical engineering perspective, the MBRB2060CTG features a molded epoxy case (D2PAK, case 418B-04) meeting UL 94 V–0 standards for flame retardance. The package is designed for automated surface mount assembly, supporting peak soldering temperatures up to 260°C for 10 seconds. Its weight (approximately 1.7 grams for D2PAK) and corrosion-resistant finish make it suitable for environments requiring long-term reliability. External terminals offer ease of solderability, and the case complies with ANSI Y14.5M dimensional standards. The package footprint matches other widely used power rectifier packages, supporting migration from legacy TO-220 designs.
