Product details
Overview
SBR10B45P5-7 from Diodes Incorporated is a 10A, 45V advanced Super Barrier Rectifier (SBR) in the POWERDI®5 surface-mount package, featuring ultra-low 0.55V max forward voltage at 10A 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 power supplies.
For engineers reviewing the SBR10B45P5-7 datasheet, SBR10B45P5-7 pinout, SBR10B45P5-7 application, or SBR10B45P5-7 equivalent, key selection criteria include thermal resistance (RθJA = 93°C/W), peak surge current rating (140A), RoHS-compliant green packaging, and stable IR performance up to +125°C - critical for high-density DC-DC and AC-DC designs.
Technical Context
This SBR rectifier employs proprietary super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature reverse leakage stability. Its 45V VRRM and 10A IO rating target mid-voltage secondary-side rectification where efficiency and thermal management are constrained.
The POWERDI®5 package delivers low-profile (1.1mm max height), high thermal efficiency (RθJC = 10°C/W), and optimized PCB pad layout per AP02001 - enabling direct replacement of larger SO-8 or TO-252 devices without board redesign.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage in reverse bias; defines safe operating range in 36–48V output rails. |
| IO (AV) | 10 A - Continuous average forward current at TA = +25°C; derates linearly above 25°C per Figure 4. |
| VF (max) | 0.55 V @ 10A, +25°C - Enables <5.5W conduction loss at full load; reduces heatsink requirements. |
| IR (max) | 0.38 mA @ 45V, +25°C - Low leakage preserves efficiency in standby and light-load conditions. |
| RθJA | 93 °C/W - Junction-to-ambient thermal resistance on 1-layer FR-4; informs minimum copper area needed for thermal compliance. |
| IFSM | 140 A @ 8.3ms - Non-repetitive surge capability; withstands typical inrush and transient events in SMPS outputs. |
| ESD HBM | 8 kV - Robust handling tolerance; reduces risk of field failure during assembly and test. |
Pinout & Package
Packaged in the compact, thermally enhanced POWERDI®5 (3.966 × 6.504 mm, 1.1 mm profile), this device uses a 3-terminal surface-mount configuration with anode, cathode, and exposed thermal pad (cathode-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to input/switch node; must route with low-inductance trace for high-frequency switching. |
| Cathode (Pin 2) | Forward current exit / common return | Electrically tied to exposed thermal pad; requires solid thermal via array to inner ground plane. |
| Thermal Pad (Bottom) | Thermal and electrical connection to cathode | Not a signal pin; soldered directly to PCB copper for RθJC = 10°C/W; must not be floated or isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.55V max at 10A/25°C - cuts conduction loss by ~30% vs. comparable Schottky diodes, improving system efficiency. |
| High-temp IR stability | 0.38mA max at 45V/25°C, with minimal increase up to +125°C - maintains low standby power in hot environments. |
| POWERDI®5 package | 1.1mm max height, 93°C/W RθJA - enables ultra-thin adapters and space-constrained DC-DC modules. |
| Green, RoHS-compliant | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); lead-free finish - meets global environmental compliance mandates. |
| ESD robustness | 8kV HBM rating - eliminates need for external ESD protection in most board-level handling scenarios. |
Applications
| AC-DC Adapters | DC-DC Converters |

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 higher IR (0.5mA @ 45V/25°C) | Marginally lower conduction loss, but less suitable for high-temp standby-critical designs | Prefer when peak efficiency at room temperature outweighs high-temp leakage concerns |
| MBR1045CT | TO-220AB dual common-cathode Schottky; 0.75V VF, 10A rating, no thermal pad | Requires heatsink; incompatible footprint; higher conduction loss and thermal resistance | Only consider for legacy through-hole designs where rework is impractical |
Compared with SBRT10U45SP5-13 and MBR1045CT, the SBR10B45P5-7 uniquely balances ultra-low VF, low IR across temperature, and compact thermal packaging - making it optimal for new space- and efficiency-constrained surface-mount power supplies.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR10B45P5-7 has an operating junction temperature range of –55°C to +150°C. For continuous 10A operation, thermal design must ensure TJ does not exceed +150°C - typically requiring ≤77°C ambient with proper PCB copper area and via count per AP02001 layout guidelines.
Is the thermal pad electrically isolated?
No. The exposed thermal pad on the POWERDI®5 package is internally connected to the cathode terminal. It must be soldered to a PCB copper area tied to the cathode net - floating or isolated pads will cause thermal and electrical failure.
How does its reverse leakage compare to standard Schottky diodes at elevated temperature?
At +125°C and 45V reverse bias, the SBR10B45P5-7 exhibits <10× lower IR than typical 45V Schottky diodes (e.g., ~1–5mA). Its proprietary barrier structure suppresses thermally activated leakage, maintaining <1.5mA even at +150°C junction temperature.
Can it replace a 10A TO-220 Schottky in existing designs?
It can replace TO-220 Schottkys in new designs where board space and thermal profile are prioritized - but not as a drop-in replacement due to different footprint, thermal interface, and mounting method. Requires PCB redesign to accommodate POWERDI®5 pad layout and thermal via strategy per AP02001.
