Product details
Overview
SBR10B45P5-13D from Diodes Incorporated is a 10A, 45V Super Barrier Rectifier (SBR) in the POWERDI5 surface-mount package, featuring ultra-low 0.55V max forward voltage at 10A/25°C and only 0.38mA max reverse leakage at 45V/25°C. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact AC-DC adapters and DC-DC converters.
For engineers reviewing the SBR10B45P5-13D datasheet, SBR10B45P5-13D pinout, SBR10B45P5-13D application, or SBR10B45P5-13D equivalent, key selection criteria include thermal resistance (RθJA = 93°C/W), surge capability (IFSM = 140A), RoHS/Green compliance, and low-profile 1.1mm height for space-constrained power stages.
Technical Context
This SBR employs a proprietary super barrier structure to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability-critical for thermally demanding power supplies. Its 10A average forward current rating and 140A non-repetitive surge capability support robust operation in transient-heavy DC-DC outputs and adapter secondary-side rectification.
The POWERDI5 package delivers RθJC = 10°C/W and enables efficient heat transfer to PCB copper, supporting continuous operation up to +150°C junction temperature. Its 12mm tape/reel packaging (5,000 units per reel) aligns with automated SMT assembly requirements for high-volume power electronics manufacturing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U45SP5-13 | Same POWERDI5 package; 0.52V VF typ at 10A but 0.58V max; 0.45mA IR max at 45V/25°C | Slightly higher leakage limits use in ultra-low-standby systems | Prefer when tighter VF distribution matters more than absolute IR minimum |
| MBR1045CT | TO-220AB dual-diode; 0.75V VF max; 1.0mA IR max; RθJA ≈ 50°C/W with heatsink | Requires mechanical mounting and heatsinking; unsuitable for SMT-only designs | Select only if through-hole assembly is mandated or >15A surge immunity is required |
Compared with SBRT10U45SP5-13 and MBR1045CT, the SBR10B45P5-13D uniquely balances ultra-low VF, low IR, SMT compatibility, and sub-1.1mm height-making it optimal for thermally constrained, high-density adapter and converter designs where board space and thermal budget are critical.

FAQ
What is the maximum junction temperature rating for SBR10B45P5-13D?
The device is rated for continuous operation from –55°C to +150°C junction temperature. This allows reliable use in sealed enclosures or under-hood automotive environments where ambient temperatures exceed +100°C, provided thermal design maintains TJ ≤ 150°C using the specified RθJA and RθJC values.
Is SBR10B45P5-13D compatible with lead-free reflow profiles?
Yes-it is qualified for standard IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports peak reflow temperatures up to 260°C. Its lead-free finish and green molding compound meet all RoHS 2 and JEDEC specifications for Pb-free assembly processes.
How does the POWERDI5 package compare thermally to SMA or SMB packages?
POWERDI5 offers RθJA = 93°C/W on 2oz FR-4-~30% lower than SMA (≈135°C/W) and ~20% lower than SMB (≈115°C/W) under identical board conditions. Its exposed cathode pad enables direct thermal conduction to inner-layer copper, significantly improving steady-state thermal performance.
Can SBR10B45P5-13D replace a standard Schottky diode like SS1045 in existing designs?
Yes-its 45V VRRM, 10A IO, and POWERDI5 footprint match SS1045 pin-for-pin. However, its lower VF (0.55V vs. 0.65V typical) reduces conduction loss, while its superior IR stability improves high-temperature reliability-requiring no layout change but delivering measurable efficiency gain.
