Product details
Overview
SBR8E45P5-13 from Diodes Incorporated is a 45 V, 5 A Super Barrier Rectifier (SBR®) in the POWERDI®5 package, featuring ultra-low 0.6 V forward voltage at 5 A and only 0.28 mA reverse leakage at 45 V/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 SBR8E45P5-13 datasheet, SBR8E45P5-13 pinout, SBR8E45P5-13 application, or SBR8E45P5-13 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJC = 8 °C/W), reverse leakage stability up to +125°C, and low-profile 1.1 mm height for space-constrained power stages.
Technical Context
This SBR rectifier uses proprietary super barrier technology to achieve lower VF than Schottky diodes while maintaining significantly better high-temperature IR stability than standard silicon PN junctions. Its 45 V VRRM rating targets secondary-side rectification in ≤12 V output AC-DC and isolated DC-DC topologies.
The POWERDI®5 package integrates an exposed bottom-side heat sink with dual anode/cathode terminals on left/right edges-requiring PCB-level connection between pins for current sharing. Thermal resistance of RθJA = 90 °C/W (on 1 oz FR-4) and RθJC = 8 °C/W enables efficient heat transfer to the board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage for secondary-side rectification in 5–12 V output supplies |
| IO(AV) | 5 A - Continuous average forward current capability at +25°C ambient |
| VF @ 5A | 0.6 V max at +25°C - Reduces conduction loss to ≤3 W per diode in 5 A applications |
| IR @ 45V | 0.28 mA max at +25°C - Low leakage preserves efficiency in standby and light-load modes |
| RθJC | 8 °C/W - Enables direct thermal coupling to PCB copper for high-power density layouts |
| Package Height | ≤1.1 mm - Fits under 1.2 mm height constraints in ultra-thin adapters and USB-PD designs |
| ESD HBM | 8 kV - Robust handling during automated assembly without additional ESD safeguards |
Pinout & Package
Supplied in the thermally enhanced POWERDI®5 surface-mount package (3.966 mm × 6.504 mm × 1.1 mm), with an exposed copper heat sink on the bottom side. Pin connections require external PCB trace linking left and right terminals to carry full 5 A current path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pad | Anode (A) | Primary anode terminal; must be connected via PCB trace to right pad for parallel current path |
| Right Pad | Anode (A) | Secondary anode terminal; electrically tied to left pad on PCB to distribute 5 A current |
| Bottom Exposed Pad | Cathode (K) | Thermal and electrical cathode node; soldered directly to large copper pour for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.6 V max at 5 A/25°C - Cuts conduction loss by ~30% vs. comparable Schottky diodes |
| High-temp IR stability | 75 µA typical at 45 V/125°C - Maintains low standby power in hot environments |
| Thermally optimized package | RθJC = 8 °C/W - Allows >60% higher power density than SO-8 equivalents |
| Low-profile footprint | 1.1 mm max height - Enables use in <12 mm thick wall adapters and portable chargers |
| Green compliance | Halogen- and antimony-free, RoHS-compliant - Meets IEC 61249-2-21 and JEDEC JS709C |

Use Value: Stable 0.28 mA IR at +25°C and 75 µA at +125°C ensures minimal standby drain across industrial temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT5A45SP5-13 | Same POWERDI®5 package; VF = 0.58 V typ at 5 A but IR = 0.35 mA max at 45 V/25°C | Slightly higher leakage limits use in ultra-low-standby designs | Prefer when lowest possible VF is critical and IR margin allows |
| PS1045L-13 | TO-277 package; VF = 0.62 V max at 5 A; RθJA = 110 °C/W; height = 1.6 mm | Larger footprint and taller profile restricts use in thin adapters | Select when legacy TO-277 layout compatibility is required over size/thermal performance |
Compared with SBRT5A45SP5-13 and PS1045L-13, the SBR8E45P5-13 delivers the best balance of low VF, low IR, and minimal height-making it optimal for next-generation compact, thermally constrained power supplies where both efficiency and volume are design priorities.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR8E45P5-13 has an operating junction temperature range of –55°C to +150°C. For continuous 5 A operation, thermal design must ensure TJ remains ≤150°C-achievable with RθJC = 8 °C/W and adequate PCB copper area, especially given its 75 µA IR at 125°C ambient.
Is the POWERDI®5 package lead-free and RoHS compliant?
Yes-the SBR8E45P5-13 features a lead-free finish and meets EU Directive 2011/65/EU (RoHS 2), including all applicable exemptions. It is also halogen- and antimony-free, certified "Green" per Diodes' specification (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb).
How should the left and right terminals be connected on the PCB?
The left and right pads are both anode terminals and must be electrically joined using a low-impedance PCB trace. This parallel connection distributes the 5 A forward current and minimizes resistive heating-failure to connect them results in single-pad current overload and potential failure.
Does this diode require a heatsink beyond the PCB copper pour?
No external heatsink is needed. The exposed bottom-side cathode pad is designed for direct soldering to a ≥1 in² 2 oz copper pour, providing sufficient thermal conduction. With RθJC = 8 °C/W and RθJA = 90 °C/W (on standard FR-4), board-level copper is the primary heatsink.
