Product details
Overview
NRVB8H100MFSWFT3G from onsemi is an automotive-grade Schottky barrier rectifier in a wettable flank DFN5 (DFNW5) package, rated for 100 V reverse voltage and 8 A average forward current at TC = 165°C, with low 0.68 V forward voltage at 8 A and 125°C junction temperature, used in high-efficiency DC/DC converters and automotive power supplies.
For engineers reviewing the NRVB8H100MFSWFT3G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC−Q101 qualification, 175°C maximum junction temperature, wettable flank package for automated optical inspection, and 75 mJ unclamped inductive switching energy rating.
Technical Context
This device operates as a unidirectional power rectifier using a planar Schottky barrier structure with integrated guardring for stress protection. It delivers low conduction loss via 0.68 V VF at 8 A/125°C and supports high-temperature operation up to TJ = 175°C with thermal resistance RθJC of 2.2°C/W into a 600 mm² copper pad.
The NRVB8H100MFSWFT3G features a full-cut SO−8 FL variant (Case 507BA, DFNW5) with wettable flanks (WF suffix), enabling post-mount solder joint inspection. Its 100 V VR rating and 75 A IFSM surge capability suit it for 12 V/24 V automotive rail clamping and synchronous rectification in buck-derived topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 100 V - blocks up to 100 V DC or repetitive AC reverse bias without breakdown |
| Avg Forward Current | 8 A at TC = 165°C - continuous conduction capability with heatsink-integrated PCB layout |
| Forward Voltage | 0.68 V at 8 A, TJ = 125°C - reduces conduction loss by ~30% vs. standard silicon diodes in same footprint |
| Junction Temp Range | −55°C to +175°C - enables under-hood deployment in engine control units and ADAS power stages |
| Surge Current | 75 A non-repetitive half-sine - withstands load dump transients in 12 V automotive systems |
| Thermal Resistance | RθJC = 2.2°C/W - allows efficient heat transfer to PCB copper when mounted per FR4 layout guidelines |
| ESD Rating | HBM Class 3B (≥8 kV), MM Class M4 - meets robustness requirements for automated assembly and field operation |
Pinout & Package
NRVB8H100MFSWFT3G uses the DFNW5 package (Case 507BA), measuring 4.90 × 5.90 × 1.00 mm with 1.27 mm pitch, featuring wettable flanks for AOI-compatible solder joint verification. The exposed thermal pad (Pin 5) must be soldered to a dedicated copper pour for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Anode | Parallel-connected input terminals accepting high-current forward bias from source rail |
| 4 | No Connect | Internally isolated; no electrical function - must remain unconnected in PCB layout |
| 5 (Exposed Pad) | Cathode / Thermal Plane | Primary cathode connection and mandatory thermal interface to PCB ground plane or heatsink copper |
Key Features
| Feature | Design Value |
|---|---|
| AEC−Q101 Qualified | Validated for automotive applications including engine control, body electronics, and infotainment power rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR8H100MFST3G | Same die, SO−8 FL package (Case 488AA); no wettable flanks; non-automotive grade marking | Lacks AEC−Q101 qualification and WF inspection capability; suitable for industrial/commercial designs only | Select when cost sensitivity outweighs automotive compliance and AOI requirements |
| STPS8H100SF | 100 V / 8 A Schottky in PowerFLAT 5x6; VF = 0.72 V @ 8 A, TJ = 125°C; no AEC−Q101 documentation found | Compatible footprint but unverified for PPAP; lower EAS (55 mJ) and higher VF increase thermal stress in high-duty-cycle EPS use | Consider only after validating AEC−Q101 status and thermal performance in target application |
Compared with MBR8H100MFST3G and STPS8H100SF, the NRVB8H100MFSWFT3G uniquely combines AEC−Q101 qualification, wettable flanks for process traceability, and 75 mJ EAS - making it the only option qualified for safety-critical automotive power stages requiring zero-defect solder joint assurance and load-dump resilience.

FAQ
What is the maximum junction temperature rating for the NRVB8H100MFSWFT3G?
The NRVB8H100MFSWFT3G has a maximum operating junction temperature of +175°C, validated per AEC−Q101 stress testing. This rating enables deployment in high-ambient locations such as near power inductors or under-hood ECUs. Derating curves in the datasheet confirm 8 A IF(AV) capability at TC = 165°C, directly supporting thermal design in constrained automotive enclosures.
Does the NRVB8H100MFSWFT3G have wettable flanks, and why does that matter?
Yes, the NRVB8H100MFSWFT3G features wettable flanks (indicated by "WF" in the part number). These chamfered side terminations allow automated optical inspection (AOI) of solder fillets post-reflow - critical for zero-defect manufacturing in automotive electronics. Unlike standard DFN packages, this design eliminates hidden voids or insufficient solder joints that could cause field failures in safety-relevant systems.
Is the NRVB8H100MFSWFT3G AEC−Q101 qualified and PPAP capable?
Yes, the NRVB8H100MFSWFT3G is explicitly AEC−Q101 qualified and PPAP capable, as stated in the official onsemi datasheet. The "NRVB" prefix denotes automotive-specific site and control change requirements, and the device undergoes full automotive qualification including HTGB, TCT, and HTRB testing. Documentation required for PPAP submission is available through onsemi's automotive support portal.
What is the thermal resistance from junction to case (RθJC) for the NRVB8H100MFSWFT3G?
The NRVB8H100MFSWFT3G has a maximum junction-to-case thermal resistance (RθJC) of 2.2°C/W, measured with a 600 mm² 1 oz. copper bond pad on FR4. This value assumes proper soldering of the exposed thermal pad (Pin 5) to a dedicated copper pour. Effective thermal design requires minimizing interfacial resistance between the pad and PCB copper to achieve the specified RθJC performance.
What does the "NRVB" prefix signify in NRVB8H100MFSWFT3G?
The "NRVB" prefix identifies the NRVB8H100MFSWFT3G as an automotive and high-reliability variant within onsemi's Schottky rectifier family. It signals unique site and control change requirements, AEC−Q101 qualification, PPAP capability, and traceability enhancements - distinguishing it from commercial-grade equivalents like MBR8H100MFST3G, which use the "MBR" prefix and lack automotive-specific controls.
