Product details
Overview
SBR15A30SP5 from Diodes Incorporated is a 15A, 30V Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring 0.59V max forward voltage at 15A/25°C, 0.1mA max reverse leakage at 30V/25°C, and thermal resistance of 3°C/W junction-to-case. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact DC-DC converters and solar panel interfaces.
For engineers reviewing the SBR15A30SP5 datasheet, SBR15A30SP5 pinout, SBR15A30SP5 application, or SBR15A30SP5 equivalent, key selection criteria include low VF stability across temperature, <1.1mm profile for thin PCBs, JEDEC-qualified reliability, RoHS/Green compliance, and thermal performance under sustained 15A conduction.
Technical Context
This SBR uses patented Super Barrier Rectifier technology to achieve lower forward voltage than Schottky diodes while maintaining superior high-temperature reverse leakage stability-0.03mA at 125°C and 30V versus typical Schottky degradation. Its PowerDI5 package enables 3°C/W RθJC with proper heatsinking, supporting continuous 15A operation in thermally constrained environments.
The device is rated for 136A non-repetitive surge (8.3ms), 460mJ single-pulse avalanche energy, and operates from –65°C to +150°C junction temperature. It exhibits 300pF junction capacitance at 15V reverse bias, making it suitable for high-frequency switching applications where low stored charge and fast recovery are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe DC or peak AC reverse operating limit. |
| IO (AV) | 15 A - Average rectified forward current at TA = +25°C with specified PCB layout; determines continuous power handling capability. |

Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced, 3-terminal plastic package with 1.1mm maximum height, matte tin-plated leads, and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to input/high-side rail; must be routed with low-inductance trace for high di/dt switching. |

Applications
| Solar Panel Bypass Diode | DC-DC Converter Output Rectifier |
|---|---|
|
Use Scenario: Installed across individual PV cell strings to prevent hot-spot damage during partial shading. IC Role / Device Role / Timing Role: Polarity-controlled bypass switch that conducts only when string voltage drops below adjacent strings. Use Value: 0.1mA IR at 125°C ensures negligible parasitic leakage under desert ambient conditions, preserving panel yield. |
Use Scenario: Secondary-side rectifier in isolated 48V-to-12V flyback or forward converter for telecom equipment. IC Role / Device Role / Timing Role: High-current unidirectional conduction path synchronized to transformer reset phase. Use Value: 0.59V VF at 15A reduces conduction loss by ~1.2W vs. standard Schottky, improving full-load efficiency by 0.8%. |
| AC-DC Adapter Freewheeling Diode | Polarity Protection in Industrial Power Inputs |
|

IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from accidental reverse battery connection. Use Value: 136A IFSM withstands 24V jump-start transients; 30V VRRM provides 2× safety margin over nominal 24V systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15BQ030-M3/45 | 30V, 15A Schottky; VF = 0.52V @ 15A/25°C but IR = 1.5mA @ 125°C - 50× higher leakage. | Less stable at elevated temperatures; unsuitable for solar bypass above 85°C ambient. | Prefer SBR15A30SP5 where high-temp leakage control is critical; choose VS-15BQ030-M3/45 only if cost sensitivity outweighs thermal drift risk. |
| ON Semiconductor SBRA1530 | 30V, 15A SBR; VF = 0.57V @ 15A/25°C, IR = 0.05mA @ 125°C; PowerFLAT 5x6 package (RθJC = 4.5°C/W). | Larger footprint (5x6mm vs. PowerDI5's 4x6.5mm); less suitable for ultra-thin adapters. | Select SBR15A30SP5 for space-constrained designs requiring <1.1mm height; SBRA1530 preferred when board area permits larger thermal pad. |
Compared with VS-15BQ030-M3/45 and SBRA1530, the SBR15A30SP5 uniquely balances ultra-low VF, sub-0.1mA room-temp leakage, <1.1mm profile, and 3°C/W thermal resistance-making it optimal for thermally dense, high-reliability solar and industrial DC-DC applications.

FAQ
What is the maximum continuous forward current rating for SBR15A30SP5?
The SBR15A30SP5 is rated for 15A average rectified forward current at TA = +25°C with minimum recommended pad layout per Diodes' package outline. Derating is required above +25°C ambient; at +85°C, the usable IO drops to approximately 10.5A based on thermal resistance and junction temperature limits.
Does SBR15A30SP5 require a heatsink for 15A operation?
No external heatsink is required for 15A continuous operation if mounted on an FR4 PCB with ≥1-inch² copper pour connected to the exposed cathode pad. With this layout, RθJA drops to 20°C/W, keeping TJ ≤ +125°C at +85°C ambient-well within the –65°C to +150°C operating range.
How does SBR15A30SP5 differ from standard Schottky rectifiers?
Unlike standard Schottky diodes, the SBR15A30SP5 uses a proprietary barrier structure that suppresses high-temperature leakage: IR remains ≤0.03mA at +125°C/30V, whereas typical Schottkys exceed 1mA under same conditions. This enables reliable operation in solar and automotive under-hood environments.
Is SBR15A30SP5 suitable for automotive applications?
The SBR15A30SP5 itself is not AEC-Q200 qualified; however, Diodes offers automotive-grade equivalents (e.g., SBR15A30SP5Q) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation. For non-automotive industrial or consumer use, the standard part meets JEDEC reliability standards and is widely deployed in automotive-adjacent systems like EV charging accessories.
