Product details
Overview
SBR8M100P5 from Diodes Incorporated is an 8A, 100V super barrier rectifier (SBR) diode in PowerDI®5 package, featuring VF(max) = 0.88 V at 8A/25°C, IR(max) = 100 µA at 100V/125°C, and rated for TJ = –55°C to +175°C. It serves as a polarity protection, recirculating, or blocking diode in automotive DC-DC and AC-DC converters.
For engineers reviewing the SBR8M100P5 datasheet, SBR8M100P5 pinout, SBR8M100P5 application, or SBR8M100P5 equivalent, key selection criteria include forward voltage drop at high temperature, surge current capability (IFSM = 160 A), junction-to-ambient thermal resistance (RθJA = 25°C/W on 2″ Al board), and AEC-Q101 readiness via automotive-grade variant SBR8M100P5Q.
Technical Context
This SBR device employs patented Super Barrier Rectifier technology to achieve lower forward voltage than standard Schottky diodes while maintaining superior high-temperature leakage performance. Its soft, fast switching behavior minimizes EMI in high-frequency power conversion stages.
The PowerDI®5 package integrates a thermally enhanced bottom-side heat sink with dual-pin anode/cathode configuration requiring PCB-level connection of left and right terminals. Junction capacitance is 245 pF at VR = 4 V, supporting stable operation in 1 MHz switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 100 V - Maximum repetitive reverse voltage; defines safe DC blocking capability in automotive battery-line circuits. |
| IO (A) | 8 A - Average rectified output current at TA = 25°C; derates to ~4.5 A at TA = 100°C per Figure 4. |
| VF (max) | 0.88 V - Measured at IF = 8 A, TJ = 25°C; enables low conduction loss in high-current 12V/48V automotive subsystems. |
| IR (max) | 100 µA - At VR = 100 V, TJ = 125°C; ensures minimal standby leakage in always-on vehicle modules. |
| IFSM | 160 A - Non-repetitive peak forward surge current (8.3 ms); withstands load-dump transients in ISO 16750-2 compliant designs. |
| TJ Range | –55°C to +175°C - Extended junction temperature range supports under-hood placement without derating penalties. |
Pinout & Package
Package: PowerDI®5 - surface-mount, thermally optimized plastic package with exposed bottom-side heat sink; dimensions: 3.966 mm × 6.51 mm × 1.10 mm (L × W × H); weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; must be electrically connected to right pin on PCB for full current path continuity. |
| Right Pin | Cathode | Current exit terminal; tied to ground or return rail; forms low-inductance loop with left pin when soldered adjacent on PCB. |
| Bottom Side | Thermal Pad / Heat Sink | Exposed copper pad for direct thermal coupling to PCB copper pour; critical for achieving RθJA = 25°C/W on aluminum board. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Enables Schottky-like VF with silicon-junction-level IR stability up to 175°C junction temperature. |
| Soft, Fast Switching | Minimizes reverse recovery ringing and EMI in 100–500 kHz DC-DC converters without snubbers. |
| +175°C Operating TJ | Supports placement near power MOSFETs or engines without thermal derating in automotive ADAS or infotainment systems. |
| Lead-Free & Halogen-Free | Meets RoHS 3 (2015/863/EU) and automotive "Green" standards (<900 ppm Br/Cl, <1000 ppm Sb). |
Applications
| Automotive Polarity Protection | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Reverse-battery connection protection in 12V/48V vehicle ECUs and body control modules. IC Role / Device Role / Timing Role: Blocking diode placed between battery input and downstream regulator; conducts only during correct polarity. Use Value: Prevents catastrophic failure during service misconnection; leverages low VF to minimize voltage drop and power loss at 8A continuous. | Use Scenario: Secondary-side rectification in synchronous or non-synchronous buck converters powering ADAS sensors. IC Role / Device Role / Timing Role: Unidirectional current path delivering regulated 3.3V/5V from 12V bus; operates at 200–300 kHz switching frequency. Use Value: Soft switching reduces EMI emissions; 175°C rating allows compact layout near hot components without thermal throttling. |
| AC-DC Front-End Rectification | Recirculating Diode in Motor Drivers |
Use Scenario: Bridge rectifier output stage in automotive auxiliary power supplies (e.g., HVAC control units). IC Role / Device Role / Timing Role: High-current freewheeling path after transformer secondary; handles 8A average and 160A surge pulses. Use Value: Low VF reduces conduction loss by >15% vs. standard FRD; high IFSM sustains reliability during line surges. | Use Scenario: Flyback diode across brushed DC motor windings in seat/mirror actuators. IC Role / Device Role / Timing Role: Provides low-loss recirculation path during PWM turn-off; clamps inductive kickback. Use Value: Fast, soft recovery prevents voltage overshoot spikes that could damage gate drivers; 245 pF CJ stabilizes switching node. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT8M100P5 | Same electrical specs; identical PowerDI5 package; differs only in marking code and traceability documentation. | No functional difference; used interchangeably in commercial designs where automotive qualification is not required. | Select SBRT8M100P5 if sourcing from alternate Diodes manufacturing lines with different lot traceability protocols. |
| SBR10M100P5 | 10A IO rating (vs. 8A); otherwise identical VR, VF, IR, and thermal specs; same PowerDI5 footprint. | Provides 25% higher current margin for future-proofing or margin-critical 12V systems with transient peaks above 8A. | Choose SBR10M100P5 when design requires headroom beyond 8A continuous or when consolidating BOMs across multiple current grades. |
Compared with SBRT8M100P5, SBR8M100P5 offers identical performance with standard commercial traceability; versus SBR10M100P5, it trades 2A current headroom for tighter cost and space optimization in volume automotive modules.

FAQ
Is SBR8M100P5 qualified to AEC-Q101?
No - SBR8M100P5 is the commercial-grade version. The automotive-qualified variant is SBR8M100P5Q, which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities. Both share identical electrical and thermal specifications.
What is the recommended PCB pad layout for PowerDI5?
Diodes specifies a symmetrical two-pad layout with 1.84 mm center-to-center spacing (e = 1.84 mm), 4.86 mm × 1.31 mm top-side pads, and a 3.054 mm × 3.549 mm thermal pad. Full dimensions and Gerber recommendations are published in Diodes' Package Outline document #AP02009.
Can SBR8M100P5 replace a standard Schottky diode in a 12V automotive circuit?
Yes - it replaces 8A Schottkys with VF ≤ 0.88 V while offering significantly better high-temperature leakage performance (IR = 2.0 µA at 125°C vs. typical Schottky >100 µA). Its soft switching also reduces EMI compared to abrupt-recovery Schottkys.
What is the thermal resistance when mounted on FR-4 PCB?
On a standard 2 oz. FR-4 board (MRP layout), RθJA = 90°C/W (Note 7). This value assumes no thermal vias or external heatsinking; adding 4–6 thermal vias under the bottom pad reduces RθJA to ~55°C/W in typical production layouts.
