Diodes Incorporated has introduced a range of automotive-compliant field-plated Super Barrier Rectifier devices in 2A, 3A, and 8A versions. Designed as drop-in alternatives to Schottky and PN junction diodes, they offer very low forward voltage and reduced reverse leakage, helping improve efficiency and reliability in DC-DC converters, reverse-polarity protection, battery chargers, automotive LED lighting, and transmission control applications.
Unlike conventional Schottky rectifiers, Diodes’ proprietary and patented SBRFP technology employs a metal oxide semiconductor (MOS) manufacturing process that overcomes the limitations of Schottky and PN junction diodes. The SBRFP8A60P5Q delivers the industry’s lowest maximum forward voltage (VF) of 0.55V at 8A, reducing conduction losses and enabling cooler operation in high-current applications. Meanwhile, the SBRFP2M60P1Q and SBRFP3M60SAFQ provide industry-leading IR leakage performance, with maximum currents of 12µA and 7µA, at 25°C and 125°C. These characteristics help improve efficiency while minimizing the risk of thermal runaway under high-temperature operating conditions.
The new devices also offer significantly greater avalanche capability than traditional Schottky rectifiers. Depending on the device, avalanche energy ratings reach up to 145mJ, enabling the rectifiers to withstand surge events, load dumps, and transient conditions commonly encountered in automotive electrical systems. This avalanche capability is five to ten times greater than conventional Schottky rectifiers, improving overall system robustness and reliability.
The SBRFP family is available in various packages, including PowerDI123 (SBRFP2M60P1Q), PowerDI5 (SBRFP8A60P5Q), and SMAF (SBRFP2M60SAFQ and SBRFP3M60SAFQ). The devices maintain stable operation across a junction temperature range of -55°C to +175°C, making them suitable for harsh automotive environments.
The SBRFP family is available in 1,000-piece quantities at:
SBRFP2M60P1Q $0.08
SBRFP8A60P5Q $0.26
SBRFP2M60SAFQ $0.11
SBRFP3M60SAFQ $0.13
