Product details
Overview
VS-6CWQ10FNTRPBF from Vishay Semiconductors is a surface-mount, dual-leg, common-cathode Schottky rectifier in D-PAK (TO-252AA) package, rated for 100 V reverse voltage and 3.5 A average forward current per leg (7 A total device), with low 0.63 V forward voltage at 3 A and 125 °C - optimized for high-frequency switching power supplies and battery protection circuits.
For engineers reviewing the VS-6CWQ10FNTRPBF datasheet, VS-6CWQ10FNTRPBF pinout, VS-6CWQ10FNTRPBF application, or VS-6CWQ10FNTRPBF equivalent, key selection criteria include its center-tap common-cathode configuration, 4.7 °C/W thermal resistance per leg, 5 mJ non-repetitive avalanche energy rating, and MSL Level 1 reflow compatibility up to 260 °C peak.
Technical Context
This dual-anode Schottky rectifier integrates two independent diode legs sharing a single cathode terminal, enabling compact center-tap topology without external interconnects. Its guard-ringed junction design enhances ruggedness against transient overvoltage and thermal stress, supporting reliable operation up to 150 °C junction temperature.
The device delivers high-frequency performance via low 92 pF junction capacitance per leg and 5.0 nH series inductance, while maintaining low conduction loss through 30.89 mΩ forward slope resistance and sub-1 V forward drop across 3–6 A at elevated temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max DC Reverse Voltage) | 100 V - supports input stages of 48 V and 60 V industrial SMPS and battery systems with margin against transients. |
| IF(AV) per leg | 3.5 A - enables continuous 7 A total output in dual-leg parallel configurations with shared thermal path. |
| VF at 3 A, 125 °C | 0.63 V - reduces conduction loss by ~35 % vs. standard silicon rectifiers, improving efficiency in high-temp environments. |
| RthJC per leg | 4.70 °C/W - allows direct PCB copper pour heatsinking for >2 W dissipation per leg without external heatsink. |
| EAS per leg | 5.0 mJ - withstands inductive flyback energy in freewheeling and reverse-battery protection applications. |
| dV/dt Rating | 10,000 V/μs - ensures stable commutation in fast-switching topologies like synchronous buck and LLC resonant converters. |
| Junction Temp Range | −40 to +150 °C - qualified for under-hood automotive auxiliary supplies and industrial motor drive auxiliary rails. |
Pinout & Package
D-PAK (TO-252AA) surface-mount package with exposed thermal pad on underside; 4-pin outline (pins 1–4), center-tap common-cathode configuration requiring no internal bond wire between anodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode Leg 1 | Independent anode connection for first Schottky diode leg; routed separately for asymmetric current sharing or dual-output designs. |
| Pin 2 | Cathode (Common) | Shared cathode node for both diode legs; must be connected to lowest system potential and thermally anchored to large copper area. |
| Pin 3 | Anode Leg 2 | Independent anode connection for second Schottky diode leg; enables center-tap rectification or dual-input redundancy. |
| Pin 4 | Thermal Pad / Cathode Extension | Exposed metal pad electrically tied to cathode; primary thermal path to PCB - requires solder mask defined stencil and full paste coverage. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protected junction | Prevents edge breakdown during repetitive surge events, extending lifetime in 440 A IFSM-rated applications. |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking - compatible with automated assembly lines using peak 260 °C profiles. |
| Low 92 pF junction capacitance | Minimizes switching losses and EMI generation in >500 kHz DC-DC converters and PFC pre-regulators. |
| 0.48 V threshold voltage (VF(TO)) | Indicates low barrier height Schottky metallization, contributing to reduced leakage and improved low-current efficiency. |
| Common cathode center-tap topology | Eliminates need for external cathode tie, reducing layout parasitics and enabling symmetrical thermal distribution across both legs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS745S | Same D-PAK package, 45 V VR, 7 A total IF(AV), but single-diode (not center-tap); VF = 0.52 V @ 3.5 A, 125 °C. | Lacks dual-anode isolation - unsuitable for center-tap or dual-input topologies; better for single-rail high-efficiency rectification. | Select STPS745S only when VR ≤ 45 V suffices and common-cathode dual-leg functionality is not required. |
| MBR20100CT | TO-220AB package, 100 V VR, 10 A total IF(AV), dual common-cathode; VF = 0.85 V @ 10 A, 25 °C; no MSL rating. | Through-hole mounting, higher VF at elevated temperature, no reflow qualification - incompatible with high-volume SMT production. | Choose MBR20100CT only for prototyping or low-volume legacy designs where thermal mass outweighs assembly constraints. |
Compared with STPS745S and MBR20100CT, VS-6CWQ10FNTRPBF uniquely combines 100 V rating, center-tap dual-anode topology, MSL Level 1 compliance, and low 0.63 V VF at 125 °C - making it the only SMT-qualified option for thermally constrained, dual-input 48–60 V industrial and telecom power stages.

FAQ
What is the maximum junction temperature rating for VS-6CWQ10FNTRPBF?
The VS-6CWQ10FNTRPBF has a maximum junction temperature (TJ max.) of +150 °C, verified per JEDEC JESD22-A108 and supported by its 4.70 °C/W RthJC per leg. This rating enables operation in sealed enclosures and high-ambient industrial environments where thermal management is limited - the VS-6CWQ10FNTRPBF maintains specified electrical parameters up to this limit when mounted on ≥1 in² 2-oz copper with thermal vias.
Does VS-6CWQ10FNTRPBF support lead-free reflow assembly?
Yes, VS-6CWQ10FNTRPBF is Pb-free (RoHS-compliant) and rated MSL Level 1 per J-STD-020, with peak reflow temperature tolerance up to 260 °C. The device requires no pre-baking and is qualified for standard SnAgCu (SAC305) reflow profiles - the VS-6CWQ10FNTRPBF's D-PAK package and internal construction ensure mechanical and electrical integrity throughout the full thermal cycle.
How is the center-tap configuration implemented in VS-6CWQ10FNTRPBF?
The VS-6CWQ10FNTRPBF implements center-tap functionality via a monolithic common-cathode structure: pins 1 and 3 serve as independent anodes, while pin 2 (and the exposed thermal pad, pin 4) form the shared cathode node. This eliminates external wiring between cathodes, reducing parasitic inductance and ensuring matched thermal coupling - the VS-6CWQ10FNTRPBF's internal layout supports true dual-leg symmetry without performance compromise.
What is the non-repetitive avalanche energy rating of VS-6CWQ10FNTRPBF?
The VS-6CWQ10FNTRPBF is rated for 5.0 mJ non-repetitive avalanche energy (EAS) per leg at TJ = 25 °C, measured with IAS = 1 A and L = 10 mH. This rating reflects robustness against inductive switching transients in freewheeling and reverse-battery protection roles - the VS-6CWQ10FNTRPBF's guard-ringed die design sustains this energy level without parameter shift or degradation under controlled test conditions.
Can VS-6CWQ10FNTRPBF replace standard silicon rectifiers in existing designs?
VS-6CWQ10FNTRPBF can replace standard silicon rectifiers in high-frequency, thermally sensitive applications - but only if VR ≥ 100 V and layout accommodates D-PAK footprint and thermal pad requirements. Unlike silicon, the VS-6CWQ10FNTRPBF exhibits higher reverse leakage (4.9 mA at 125 °C), so designs with strict standby power budgets require validation - the VS-6CWQ10FNTRPBF's lower VF improves efficiency but demands attention to thermal anchoring and PCB copper area.
