Product details
Overview
SBR10E45P5 from Diodes Incorporated is a 10A, 45V Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring ultra-low 0.47V max forward voltage at 10A/25°C and only 0.28mA max reverse leakage at 45V/125°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 SBR10E45P5 datasheet, SBR10E45P5 pinout, SBR10E45P5 application, or SBR10E45P5 equivalent, key selection criteria include forward voltage drop at full load, high-temperature reverse leakage stability, thermal resistance (RθJA = 88°C/W), and compatibility with thin-profile, thermally constrained power designs.
Technical Context
This SBR uses patented Super Barrier Rectifier technology to achieve Schottky-like low VF without the high IR trade-off typical of conventional Schottky diodes. Its junction-to-case thermal resistance is 14°C/W, enabling efficient heat transfer to PCB copper in the PowerDI5 package.
The device operates across –55°C to +150°C and sustains 275A non-repetitive surge current (8.3ms). Reverse leakage remains tightly controlled-0.05mA typical at 125°C-making it suitable for high-ambient industrial and adapter applications where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage before breakdown; sets upper limit for input/output rail isolation in 36V nominal systems. |
| IO (AV) | 10 A - Continuous average forward current rating; supports ≥10W power conversion with appropriate PCB copper area. |
| VF Max | 0.47 V @ 10A, 25°C - Enables <4.7W conduction loss per diode at full load, critical for efficiency-critical 10W+ adapters. |
| IR Max | 0.28 mA @ 45V, 125°C - Low high-temp leakage preserves system standby power budget and prevents thermal runaway in enclosed environments. |
| RθJA | 88 °C/W - Thermal resistance to ambient on 2″×2″ Al board; defines required minimum copper area for safe operation at 10A. |
| IFSM | 275 A - Surge capability handles inrush and transient overloads in offline SMPS without failure. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced, low-profile (≤1.1 mm height), lead-free, RoHS- and "Green"-compliant molded plastic package with exposed cathode pad for improved thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current terminal | Connected to source side (e.g., transformer secondary or switch node); carries full forward current during conduction. |
| Cathode (Exposed Pad + Lead 2) | Output current terminal | Electrically and thermally connected to PCB copper pour; primary path for heat extraction and return current routing. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Combines low VF (0.47V) and low IR (0.28mA @125°C), eliminating Schottky's high-leakage limitation in high-temp operation. |
| Thermally Efficient PowerDI5 | RθJC = 14°C/W enables direct thermal coupling to PCB ground plane, reducing junction temperature rise by >30% vs. SO-8 equivalents. |
| Thin Profile (≤1.1 mm) | Enables use in space-constrained USB-C PD adapters, slim wall-wart chargers, and stacked multilayer PCBs. |
| Halogen & Antimony Free | Meets IEC 61249-2-21 "Green" standard (<900ppm Br, <900ppm Cl, <1000ppm Sb), supporting eco-compliance in EU/Asia markets. |
Applications
| AC-DC Adapters & Chargers | DC-DC Converters |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 12–24V output, 10–30W flyback or QR controllers. IC Role / Device Role / Timing Role: Freewheeling rectifier replacing MOSFETs or standard Schottkys to reduce conduction loss and simplify gate drive. Use Value: 0.47V VF cuts conduction loss by ~35% vs. 0.72V Si diodes, improving adapter efficiency from 85% to ≥87.5% at full load. | Use Scenario: Output rectification in isolated 5–12V buck-derived converters for FPGA, DSP, or PMIC rails. IC Role / Device Role / Timing Role: High-current output rectifier handling continuous 10A load with minimal thermal derating. Use Value: Stable 0.05mA IR at 125°C prevents output rail droop and ensures reliable regulation under sustained high-ambient conditions. |
| Polarity Protection Circuits | Industrial Power Supplies |
Use Scenario: Input reverse-polarity protection in 24V/48V industrial modules with limited board space. IC Role / Device Role / Timing Role: Series-blocking diode placed before main DC-DC stage to prevent damage from miswired inputs. Use Value: 0.47V drop adds only 1.95W loss at 4.2A (typical 24V system), minimizing heat sink requirements vs. higher-VF alternatives. | Use Scenario: Auxiliary supply rectification in programmable logic controllers (PLCs) operating continuously at 70–85°C ambient. IC Role / Device Role / Timing Role: Primary bulk rectifier for 5V/3.3V auxiliary rails feeding microcontrollers and sensors. Use Value: RθJA = 88°C/W and robust 150°C max TJ allow uninterrupted operation without forced air, reducing system BOM cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10BQ040-M3 | 40V VRRM, 0.45V VF @ 10A, 0.5mA IR @ 125°C - lower blocking voltage, higher leakage. | Not suitable for 45V-rated systems; acceptable only in ≤40V designs with relaxed leakage budgets. | Select only if VRRM margin <5V is acceptable and thermal environment stays ≤105°C. |
| ON Semiconductor SBRT10U45 | 45V VRRM, 0.49V VF @ 10A, 0.2mA IR @ 125°C - slightly higher VF, lower IR, same package. | Better leakage control but sacrifices ~0.02V conduction efficiency; preferred in ultra-low-standby systems. | Choose when IR-driven standby power is more critical than full-load efficiency. |
Compared with VS-10BQ040-M3 and SBRT10U45, the SBR10E45P5 delivers optimal balance: highest VRRM margin (45V), lowest VF among 45V-class SBRs, and industry-leading IR stability up to 125°C-making it ideal for thermally aggressive, efficiency-sensitive 10W+ adapters.

FAQ
What is the maximum junction temperature and how does it affect layout?
The SBR10E45P5 has a maximum junction temperature of +150°C. To maintain safe operation at 10A, its RθJA of 88°C/W requires ≥2-inch² of 2-oz copper on the cathode pad. Thermal vias under the exposed pad and connection to internal ground planes further reduce θJA by up to 25%, preventing thermal shutdown in sealed enclosures.
Is the PowerDI5 package compatible with standard reflow profiles?
Yes-the PowerDI5 package is qualified for lead-free reflow per J-STD-020, with peak temperatures up to 260°C. Its matte tin finish and annealed copper leadframe ensure reliable solder wetting. Recommended profile includes ramp rate ≤3°C/s, preheat 150–200°C for 60–120s, and time above liquidus (217°C) of 60–90s.
How does SBR technology differ from standard Schottky and fast recovery diodes?
SBR technology uses a modified epitaxial structure that lowers barrier height while suppressing minority-carrier injection-achieving VF near Schottky levels (0.47V) but with IR characteristics closer to fast recovery diodes (0.28mA @125°C). This avoids the thermal runaway risk of Schottkys and the higher switching losses of fast recovery types.
Can SBR10E45P5 replace a 10A TO-220 rectifier in existing designs?
No-it is not a drop-in replacement due to different package, thermal path, and pinout. While electrically compatible (same VRRM/IO), the PowerDI5 requires revised PCB layout: larger copper area for thermal management, no mounting hole, and dual-terminal (anode/cathode) routing instead of three-terminal TO-220. Thermal simulation is recommended before redesign.
