Diodes Incorporated has introduced a new family of automotive-compliant Field-Plated Super Barrier Rectifiers (SBRFP). The devices combine ultra-low forward voltage, low reverse leakage and high avalanche capability to improve efficiency and reliability in demanding automotive power applications.
Diodes Incorporated Field-Plated Super Barrier Rectifiers (SBRFP) for automotive
Key Characteristics
- Technology: Proprietary field-plated Super Barrier Rectifier (SBR) based on MOS process
- Current ratings: 2 A, 3 A and 8 A versions
- Standout model: SBRFP8A60P5Q — maximum forward voltage of only 0.55 V at 8 A
- Low reverse leakage:
- SBRFP2M60P1Q: max 12 µA
- SBRFP3M60SAFQ: max 7 µA
- Avalanche energy capability: up to 145 mJ (5–10× higher than conventional Schottky rectifiers)
- Maximum junction temperature: 175°C
- Operating temperature range: −55°C to +175°C
- Packages: PowerDI123, PowerDI5 and SMAF
- Automotive-compliant design for harsh transient environments
- Drop-in alternatives to Schottky and PN-junction rectifiers
The field-plated SBR structure delivers the rare combination of low conduction losses, low leakage at high temperature and superior surge/transient robustness — critical for modern vehicle power networks.
Target Applications
- DC-DC converters
- Reverse-polarity protection
- Battery charging circuits
- Automotive LED lighting
- Transmission control systems
The initial portfolio includes SBRFP2M60P1Q, SBRFP2M60SAFQ, SBRFP3M60SAFQ and SBRFP8A60P5Q.
