Product details
Overview
SBR5E45P5-7D from Diodes Incorporated is a 5A, 45V Super Barrier Rectifier (SBR®) in the POWERDI®5 package, featuring ultra-low 0.6V max forward voltage at 5A and 0.28mA 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 SBR5E45P5-7D datasheet, SBR5E45P5-7D pinout, SBR5E45P5-7D application, or SBR5E45P5-7D equivalent, key selection criteria include thermal resistance (RθJA = 90°C/W), high-temperature IR stability (75µA at 125°C), low-profile 1.1mm height, and RoHS-compliant green packaging.
Technical Context
This Super Barrier Rectifier employs a proprietary epitaxial structure to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature reverse leakage performance. Its 45V VRRM rating and 120A non-repetitive surge capability support robust operation in switching power supplies with transient overloads.
The POWERDI®5 package integrates a bottom-side heat sink for enhanced thermal conduction, enabling higher current density in space-constrained designs. Its 8°C/W junction-to-case thermal resistance supports reliable operation up to +150°C junction temperature under proper PCB layout.
Key Specifications

| IO(AV) | 5A - Continuous average forward current at +25°C ambient on standard FR-4 PCB |
| VF(MAX) | 0.6V @ 5A, 25°C - Limits conduction loss to ≤3W per diode in high-current paths |
| IR(MAX) | 0.28mA @ 45V, 25°C - Ensures minimal standby power loss in offline converters |
| RθJA | 90°C/W - Requires ≥100mm² copper pour for full 5A derating at +70°C ambient |
| IFSM | 120A @ 8.3ms - Withstands typical AC line surge events without failure |
| TJ Range | –55°C to +150°C - Enables use in automotive under-hood and industrial environments |

|---|---|
Use Scenario: Secondary-side synchronous rectification in 12–65W USB PD wall adapters. IC Role / Device Role / Timing Role: Freewheeling rectifier replacing MOSFETs in cost-sensitive designs where gate drive complexity must be avoided. Use Value: Delivers >92% efficiency at 5V/3A output with no control circuitry, reducing BOM count and layout area. | Use Scenario: Output rectification in isolated flyback or forward converters for industrial sensors. IC Role / Device Role / Timing Role: High-reliability output diode handling 5A continuous load with minimal thermal rise on 2-layer PCBs. Use Value: Maintains <0.3V drop at 125°C, avoiding efficiency collapse in enclosed enclosures without forced air. |
| Polarity Protection | Automotive Body Electronics |
Use Scenario: Reverse-voltage protection at 12V/5A input rails in smart home hubs and PoE-powered devices. IC Role / Device Role / Timing Role: Low-loss series protection diode placed before LDOs or PMICs. Use Value: 0.6V drop limits power dissipation to 3W-enabling use without heatsink in sealed enclosures. | Use Scenario: Power rail conditioning in automotive infotainment display modules operating at ambient –40°C to +85°C. IC Role / Device Role / Timing Role: Input rectifier and ESD clamp in 12V supply path with 8kV HBM rating. Use Value: Stable 0.28mA IR at 25°C and 75µA at 125°C prevents battery drain in always-on modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT5A45-13 | Same 45V/5A rating but TO-277 package; RθJA = 110°C/W; VF = 0.59V typ | Larger footprint; less suitable for ultra-thin designs; requires more board area for thermal relief | Prefer when legacy TO-277 footprint compatibility is required and height is not constrained |
| PS1045L-13 | 45V/10A rating in POWERDI®5; VF = 0.62V max; IR = 0.35mA max at 25°C | Higher current capacity but higher leakage; larger die size increases capacitance (CT = 120pF vs. 85pF) | Choose only if 10A rating is needed; otherwise SBR5E45P5-7D offers better IR/VF trade-off at 5A |
Compared with SBRT5A45-13 and PS1045L-13, the SBR5E45P5-7D delivers the lowest combination of forward voltage and high-temperature leakage in the POWERDI®5 form factor-making it optimal for thermally dense, space-limited 5A rectification where efficiency and reliability across temperature are critical.

FAQ
What is the maximum recommended PCB copper area for full 5A operation at +70°C ambient?
A minimum 100mm² of 2oz copper connected to the bottom heat sink pad is required to maintain junction temperature below +150°C at 5A and +70°C ambient, based on the specified RθJA of 90°C/W and thermal simulation data from Diodes' AP02002 layout guidelines.
Does the SBR5E45P5-7D require a heatsink for 5A continuous operation?
No external heatsink is required. The POWERDI®5 package's bottom-side thermal pad, when soldered to ≥100mm² of 2oz copper, provides sufficient heat dissipation. RθJC of 8°C/W enables direct PCB thermal conduction-eliminating need for mechanical heatsinks in most applications.
How does the SBR5E45P5-7D compare to standard Schottky rectifiers in high-temperature operation?
At +125°C and 45V reverse bias, its IR is 75µA-up to 10× lower than typical Schottkys (which exceed 500µA). This directly improves no-load efficiency and reduces thermal runaway risk in enclosed, high-ambient environments like LED drivers and industrial power supplies.
Is the SBR5E45P5-7D suitable for automotive under-hood applications?
Yes-it is qualified for TJ = –55°C to +150°C and features 8kV HBM ESD rating. However, it is not AEC-Q101 qualified; for automotive safety-critical systems, Diodes' AEC-Q101-certified SBR variants (e.g., SBR5E45Q-7D) must be used instead.
