Low Forward Voltage Surface-Mount Rectifiers for Efficient and Thermal Stable Power Conversion
MCC introduces the MBRB40xxCTQ and MBRD20xxCTQ Series, a family of automotive‑grade surface‑mount Schottky Barrier Rectifiers designed for high‑current power conversion with controlled power loss and efficient heat dissipation. Offered in compact DPAK and thermally efficient D2-PAK packages, these devices support high power density designs while maintaining stable electrical performance and long‑term reliability in demanding environments.
Featuring low forward voltage drop, fast switching performance, and high junction temperature capability, the MBRB40xxCTQ and MBRD20xxCTQ Series improves overall efficiency and reduces thermal stress in high‑frequency and high‑power applications. AEC‑Q101 qualification, UL‑rated molded packages, and MSL 1 reliability further ensure consistent and dependable operation in automotive and industrial power systems.
AEC-Q101 Schottky Barrier Rectifiers
Features & Benefits:
- High current capability for demanding power conversion stages
- Low forward voltage drop (typ. < 0.93 V) to improve efficiency and reduce power loss
- Fast switching speed with low stored charge for high‑frequency operation
- Automotive‑qualified to AEC‑Q101 standards
- Maximum junction temperature up to 150 °C or 175 °C (model dependent)
- DPAK (TO‑252) package for compact, space‑constrained designs
- D2-PAK (TO‑263) package for enhanced thermal dissipation in high‑power applications
Applications
These Schottky rectifiers are well suited for a wide range of power conversion, protection, and control applications where efficiency, thermal performance, and reliability are critical. Their fast-switching behavior and automotive-grade qualification make them suitable for both industrial and automotive system designs.
