Product details
Overview
SBR5E45P5-13 from Diodes Incorporated is a 5A, 45V Super Barrier Rectifier (SBR®) in the POWERDI®5 surface-mount package. It delivers ultra-low forward voltage (0.6 V max at 5 A, 25°C), low reverse leakage (0.28 mA max at 45 V, 25°C), and stable high-temperature performance-ideal for secondary-side rectification in compact AC-DC adapters and DC-DC converters.
For engineers reviewing the SBR5E45P5-13 datasheet, SBR5E45P5-13 pinout, SBR5E45P5-13 application, or SBR5E45P5-13 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 compatibility with thin-profile, high-power-density board layouts.
Technical Context
This Super Barrier Rectifier uses a proprietary epitaxial structure to achieve lower VF than standard Schottky diodes while maintaining superior IR stability at elevated temperatures-unlike conventional Schottkys, it avoids rapid leakage rise above 85°C. Its 45 V VRRM rating targets mid-voltage secondary-side rectification where higher blocking voltage is needed without sacrificing efficiency.
The POWERDI®5 package integrates a bottom-side heat sink directly under the die, enabling efficient thermal conduction to the PCB copper plane. With RθJA = 90 °C/W on a 1-in² 2-oz FR-4 board, it supports sustained 5 A operation in thermally constrained spaces when properly laid out.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Blocks up to 45 V reverse voltage, suitable for 36 V nominal output rails with margin. |
| IO(AV) | 5 A - Continuous average forward current rating at 25°C ambient, derated above 25°C per Figure 4. |
| VF(max) | 0.6 V @ 5 A, 25°C - Reduces conduction loss to ≤3 W at full load, critical for >10 W adapter efficiency. |
| IR(max) | 0.28 mA @ 45 V, 25°C - Low leakage preserves no-load power budget and enables stable operation at 125°C (75 µA typ). |
| RθJC | 8 °C/W - Enables direct junction-to-PCB thermal path; requires soldered bottom-side thermal pad for rated performance. |
| ESD HBM | 8 kV - Robust handling tolerance reduces risk of field failure during assembly and test. |
Pinout & Package
Package: POWERDI®5 - thermally enhanced surface-mount package with exposed bottom-side copper heat sink (0.093 g mass). Dimensions: 4.0 mm × 6.5 mm × 1.1 mm max height. UL 94V-0 mold compound; RoHS, halogen- and antimony-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Forward current input | Connected to switching node or transformer secondary; must be routed with low-inductance trace. |
| Cathode (Right Pin) | Forward current output / reverse voltage reference | Connected to output rail; serves as return path and voltage clamp reference. |
| Bottom Heat Sink | Thermal interface / mechanical ground | Electrically isolated but thermally conductive; must be soldered to large copper pour for RθJC performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at 5 A | 0.6 V max enables ≥1.5% efficiency gain over 0.75 V Schottky in 12 V/5 A DC-DC outputs. |
| Stable IR up to +125°C | Leakage remains ≤75 µA at 125°C, avoiding thermal runaway in enclosed adapters. |
| POWERDI®5 thermal design | 8 °C/W junction-to-case allows 5 A continuous operation with <25°C temperature rise over PCB plane. |
| Thin 1.1 mm profile | Enables use in <12 mm total height consumer chargers and slim industrial power modules. |
Applications
| AC-DC Adapters & Chargers | DC-DC Converters |
|---|---|

Use Scenario: Input reverse-polarity protection in 5–45 V embedded systems with space-constrained PCBs. IC Role / Device Role / Timing Role: Series-blocking diode ensuring safe operation when external power is misconnected.

Use Value: 1.1 mm height and bottom-heat-sink design allow stacking with adjacent ICs in <10 mm vertical envelope. |
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 45 V/5 A rating; VF = 0.58 V max; slightly lower IR (0.25 mA @ 45 V, 25°C); identical POWERDI®5 footprint. | Optimized for lowest possible conduction loss in high-efficiency telecom supplies. | Select if <0.02 V VF reduction justifies sourcing from alternate Diodes product line. |
| SS5P4 | 45 V/5 A Schottky; VF = 0.52 V typ but IR = 0.5 mA @ 25°C and rises sharply above 85°C (≥5 mA @ 125°C). | Acceptable only in well-cooled, low-ambient environments; unsuitable for sealed enclosures. | Choose only when cost sensitivity outweighs thermal reliability requirements. |
Compared with SBRT5A45-13, SBR5E45P5-13 offers identical thermal and electrical specs but different internal process tuning; versus SS5P4, it trades 0.02 V higher VF for 5× lower high-temp leakage and robustness in unventilated designs.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR5E45P5-13 has an operating junction temperature range of –55°C to +150°C. For reliable continuous operation at 5 A, thermal design must limit TJ to ≤140°C using the specified RθJC = 8 °C/W and proper PCB copper area. Derating begins at 25°C ambient per Figure 4.
Is the bottom heat sink electrically isolated?
Yes-the bottom thermal pad of the POWERDI®5 package is electrically isolated from both anode and cathode terminals. It serves solely as a thermal interface and must be connected to a non-current-carrying copper pour or thermal plane on the PCB.
Can this diode replace a standard Schottky in existing designs?
Yes, with layout verification: the POWERDI®5 footprint matches common 5-pin SO-type pads, but the bottom thermal pad requires dedicated stencil aperture and solder paste volume. Electrical replacement is valid for 45 V/5 A Schottkys, though VF is slightly higher (0.6 V vs. 0.52 V typ) while IR is significantly lower.
What is the moisture sensitivity level (MSL) rating?
The SBR5E45P5-13 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and does not require dry pack or baking prior to reflow soldering under standard conditions.
