The SBR10U45SP5-13 from Diodes Incorporated is a 10A Super Barrier Rectifier featuring patented SBR® technology. It combines an ultra-low forward-voltage drop with excellent high-temperature stability and high surge-current capability, making it especially suitable for solar-panel bypass, power rectification and high-efficiency power-conversion applications.
The device is rated for 45V peak repetitive reverse voltage, 45V working peak reverse voltage and 45V DC blocking voltage, with a 32V RMS reverse-voltage rating. Maximum average rectified output current is 10A.
Low conduction loss is a key advantage. At 10A and TJ=25°C, forward voltage is typically 0.42V and 0.47V maximum. At TJ=125°C and 10A, VF is approximately 0.38V typical and 0.41V maximum, helping reduce power dissipation in high-current rectification circuits.
The SBR10U45SP5 provides excellent surge capability, with a 275A non-repetitive peak forward surge current under an 8.3ms single-half-sine-wave condition. Repetitive peak avalanche power is specified at 30kW for a 1µs pulse at 25°C.
Minimum reverse breakdown voltage is 45V at 0.3mA. At 45V reverse bias and TJ=25°C, typical leakage current is 0.05mA, with a maximum specification of 0.3mA. The device is selectively rated for very high junction temperatures, reaching up to 200°C in DC forward mode under the conditions defined by Diodes Incorporated.
The exact SBR10U45SP5-13 ordering option uses the thermally efficient PowerDI5 surface-mount package, with maximum body dimensions of approximately 6.60 × 4.05 × 1.15mm. It is MSL Level 1, lead-free, RoHS compliant, halogen- and antimony-free, and supplied in 5,000-piece tape-and-reel packaging.
For automotive-qualified designs, Diodes specifies the separate SBR10U45SP5Q version; the requested SBR10U45SP5-13 is the standard device. The exact -13 part also remains listed among products being offered in a 2025 Diodes PCN.
