Product details
Overview
SBR5E45P5-13D from Diodes Incorporated is a 5A, 45V Super Barrier Rectifier (SBR®) in the POWERDI®5 surface-mount package, featuring ultra-low 0.6V max forward voltage at 5A/25°C and only 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 SBR5E45P5-13D datasheet, SBR5E45P5-13D pinout, SBR5E45P5-13D application, or SBR5E45P5-13D equivalent, key selection criteria include thermal resistance (RθJA = 90°C/W), high-temperature IR stability (75µA @ 125°C), low-profile 1.1mm height, RoHS-compliant lead-free finish, and ESD robustness (8kV HBM).
Technical Context
This Super Barrier Rectifier uses a proprietary epitaxial structure to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature reverse leakage performance. Its 45V VRRM rating targets secondary-side rectification in ≤12V output power supplies.
The POWERDI®5 package integrates a bottom-side heat sink with thermally efficient 8°C/W RθJC, enabling higher current density in space-constrained layouts. Pin configuration supports PCB-level thermal management via direct copper pad connection to the cathode terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse blocking voltage; suitable for 12V-output DC-DC and AC-DC secondary rectification. |
| IO(AV) | 5 A - Average forward current rating at 25°C ambient; derates to ~3.5A at 85°C per Figure 4. |
| VF(max) | 0.6 V @ 5A, 25°C - Enables <3W conduction loss at full load, reducing thermal stress in thin-profile adapters. |
| IR(max) | 0.28 mA @ 45V, 25°C - Low leakage preserves efficiency in standby mode; rises to 75µA at 125°C (not catastrophic). |
| RθJA | 90 °C/W - Measured on 1-layer FR-4 board; requires ≥200mm² copper pour for safe 5A operation at 70°C ambient. |
| ESD HBM | 8 kV - Robust handling tolerance eliminates need for additional ESD protection in assembly lines. |
Pinout & Package
Package: POWERDI®5 - thermally enhanced surface-mount package with exposed bottom-side cathode pad (heat sink), 1.1mm profile, and 3.966mm × 6.504mm footprint. Molded green compound, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left) | Input current terminal | Connected to source (e.g., transformer secondary or switching node); must be routed with low-inductance trace. |
| Cathode (Right) | Output current terminal | Electrically tied to bottom-side thermal pad; requires solid copper connection for thermal and electrical return path. |
| Thermal Pad (Bottom) | Common cathode / heat sink | Not electrically isolated; must be soldered to ≥200mm² internal/external copper plane for RθJA compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.6V max @ 5A/25°C - reduces conduction loss by ~30% vs. comparable Schottky diodes, directly improving adapter efficiency. |
| High-temp IR stability | 75µA @ 125°C, 45V - maintains low standby power in hot environments without thermal runaway risk. |
| Thermally efficient package | RθJC = 8°C/W - enables >75% of junction heat to transfer directly to PCB, supporting higher power density. |
| Low-profile construction | 1.1mm max height - fits within 12mm-thick laptop adapters and slim USB-C chargers. |
Applications
| AC-DC Adapters & Chargers | DC-DC Converters |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in 10–30W USB PD wall adapters. IC Role / Device Role / Timing Role: Freewheeling rectifier replacing MOSFET + driver in cost-sensitive designs; conducts during low-side switch off-time. Use Value: Eliminates gate drive complexity while delivering 0.6V VF and 0.28mA IR - matching Schottky efficiency with better thermal margin. |
Use Scenario: Output rectification in isolated flyback or forward converters for industrial IoT power modules. IC Role / Device Role / Timing Role: Uncontrolled rectifier in fixed-frequency 100–500kHz topologies; handles continuous 5A DC output current. Use Value: Stable 75µA IR at 125°C ensures no efficiency collapse in sealed enclosures, unlike standard Schottkys. |
| Polarity Protection Circuits | Automotive Body Electronics |
|
Use Scenario: Reverse-voltage protection at 12V input rails of embedded controllers and sensor nodes. IC Role / Device Role / Timing Role: Series-blocking diode placed before LDO or buck converter input; conducts only during correct polarity. Use Value: 0.6V drop minimizes voltage headroom loss vs. 0.8–1.2V of standard silicon diodes, preserving regulation margin. |
Use Scenario: Power rail protection in automotive cabin modules (e.g., mirror controls, seat memory) operating up to 105°C ambient. IC Role / Device Role / Timing Role: Input rectifier and surge clamp in 12V supply paths subjected to load dump transients. Use Value: 120A IFSM rating withstands ISO 7637-2 pulse 5a; 8kV HBM ESD protects against assembly-line discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT5A45SP5-13 | Same 45V/5A rating but uses Schottky architecture; VF = 0.52V typ @ 5A, but IR = 1.2mA @ 125°C. | Better VF at room temp, but higher leakage above 85°C limits use in sealed automotive modules. | Prefer for room-temp-only consumer adapters where lowest conduction loss is critical. |
| PS1045L-13 | 45V/10A SBR in POWERDI®123; VF = 0.62V @ 10A, RθJA = 65°C/W, larger 3.5mm × 4.5mm footprint. | Higher current capability and better thermal performance, but incompatible footprint and layout. | Select when system requires >5A average current or tighter thermal budget; not drop-in. |
Compared with SBRT5A45SP5-13, SBR5E45P5-13D trades marginal VF increase for 5× lower IR at 125°C - critical for reliability in enclosed environments. Against PS1045L-13, it offers identical VF and SBR benefits in half the area, accepting higher RθJA for space-constrained designs.

FAQ
What is the thermal pad connection requirement for SBR5E45P5-13D?
The bottom-side thermal pad is electrically connected to the cathode and must be soldered to a minimum 200 mm² copper area on the PCB. This provides both electrical return path and thermal conduction; omitting this pad increases RθJA by >40% and risks thermal shutdown at 5A load.
Can SBR5E45P5-13D replace a standard Schottky diode in an existing design?
Yes, if the original Schottky has comparable VRRM and IO ratings. However, verify that the PCB pad layout matches POWERDI®5 dimensions (3.97mm × 6.50mm) and that the cathode thermal pad is fully exposed and connected - many Schottky footprints lack adequate copper for this package's thermal pad.
How does SBR5E45P5-13D perform under transient overcurrent conditions?
It withstands non-repetitive 120A surge current for 8.3ms (per IEC 61000-4-5), making it suitable for load-dump and inrush scenarios in automotive body electronics. Derating curves in Figure 4 confirm sustained 5A operation up to 70°C ambient with proper PCB copper.
Is SBR5E45P5-13D qualified for automotive applications?
While not AEC-Q101 certified, its -55°C to +150°C operating range, 120A IFSM rating, and stable IR up to 125°C support use in non-safety-critical automotive body electronics (e.g., lighting control, HVAC actuators). For safety-critical systems, Diodes' AEC-Q101-qualified SBR variants should be selected.
