Product details
Overview
VS-6CWQ04FNTRPBF from Vishay Semiconductors is a surface-mount, common-cathode, center-tap Schottky rectifier in D-PAK (TO-252AA) package, rated 40 V reverse voltage, 3.5 A average forward current per leg (7 A total), with 0.49 V forward voltage at 3 A and 125 °C - used in DC/DC converters and battery protection circuits.
For engineers reviewing the VS-6CWQ04FNTRPBF datasheet, VS-6CWQ04FNTRPBF pinout, VS-6CWQ04FNTRPBF application, or VS-6CWQ04FNTRPBF equivalent, key selection criteria include low VF for efficiency, MSL Level 1 reflow compatibility, 150 °C max junction temperature, and dual-leg common-cathode topology for compact power stage design.
Technical Context
This dual-anode Schottky rectifier integrates two independent 40 V / 3.5 A legs sharing a single cathode terminal, enabling synchronous freewheeling or dual-output rectification without external parallel diodes. Its guard ring structure enhances ruggedness against avalanche stress and thermal cycling.
Designed for high-frequency switching (dV/dt up to 10,000 V/μs), it delivers low conduction loss (rt = 37.33 mΩ) and low junction capacitance (189 pF at 5 V), minimizing switching losses in 100 kHz–1 MHz SMPS topologies while maintaining stable operation from –40 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max DC Reverse Voltage) | 40 V - supports input rails up to 36 V nominal with margin for transient spikes in automotive and industrial supplies. |
| IF(AV) per leg | 3.5 A - enables continuous 7 A total output when both legs operate in parallel configuration with shared cathode. |
| VF at 3 A, 125 °C | 0.49 V - reduces conduction loss to ~1.47 W per leg, critical for thermally constrained PCB layouts. |
| RthJC per leg | 4.70 °C/W - allows direct heatsinking to copper pour; 2.35 °C/W device-level thermal resistance improves thermal management scalability. |
| EAS per leg | 8.0 mJ - withstands single-event inductive energy surges typical in motor drive flyback and buck converter freewheeling. |
| CT at 5 V | 189 pF - limits capacitive turn-on loss and EMI generation in high-speed switching applications. |
| dV/dt rating | 10,000 V/μs - ensures reliable commutation in fast-switching SiC/GaN-based converters without false triggering. |
Pinout & Package
D-PAK (TO-252AA) package with exposed thermal pad on underside; 3-pin outline (2 anodes + 1 common cathode); MSL Level 1 compliant; lead (Pb)-free; tape-and-reel packaging (TR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | First Schottky anode | Connects to first switching node (e.g., high-side switch drain or transformer secondary winding end A). |
| 2 (Cathode) | Common cathode | Shared return path for both legs; must be routed to low-inductance ground/power plane for optimal thermal and EMI performance. |
| 3 (Anode B) | Second Schottky anode | Connects to second switching node (e.g., second transformer winding end or auxiliary rail source). |
Key Features
| Feature | Design Value |
|---|---|
| Center-tap common-cathode configuration | Enables dual-output or interleaved rectification with single-package footprint, reducing board area vs. discrete dual-diode solutions. |
| Guard ring construction | Improves long-term reliability under repetitive avalanche stress and high dv/dt conditions, extending lifetime in harsh environments. |
| Low forward slope resistance (37.33 mΩ) | Minimizes I²R heating at high load currents, supporting sustained 3.5 A/leg operation without derating at TC = 135 °C. |
| MSL Level 1 reflow compatibility | Permits standard Pb-free reflow profiles (peak 260 °C) without preconditioning, simplifying SMT assembly and reducing process risk. |
| 150 °C maximum junction temperature | Supports operation in sealed enclosures or high-ambient environments (e.g., automotive under-hood, industrial motor drives). |
Applications
| Server Power Supply Rectification | Battery Charging Circuit |
|---|---|
Use Scenario: High-efficiency 12 V/48 V intermediate bus conversion in rack-mounted server PSUs using synchronous buck topology. IC Role / Device Role / Timing Role: Freewheeling Schottky rectifier replacing MOSFET body diode to reduce conduction loss during low-side switch off-time. Use Value: 0.49 V VF at 3 A/125 °C cuts rectifier loss by >35% vs. standard 0.75 V Si diode, improving full-load efficiency by ~0.8%. | Use Scenario: Dual-battery charging system in portable medical equipment requiring reverse-polarity protection and charge-path isolation. IC Role / Device Role / Timing Role: Common-cathode dual-anode diode providing independent charge path control and reverse battery blocking for two Li-ion cells. Use Value: 40 V VR rating accommodates 16.8 V (4S) Li-ion stack plus safety margin; low VF prevents excessive heat buildup during 3 A continuous charge. |

IC Role / Device Role / Timing Role: Output rectifier in high-frequency (500 kHz) buck regulator handling peak loads during image capture bursts. Use Value: 189 pF CT and 10,000 V/μs dV/dt rating suppress switching noise and prevent false turn-on during fast voltage transitions. | Use Scenario: Freewheeling path in 24 V BLDC motor driver half-bridge where inductive kickback must be clamped rapidly. IC Role / Device Role / Timing Role: Snubberless flyback diode absorbing stored inductive energy during PWM dead-time intervals. Use Value: 8 mJ EAS per leg handles typical motor phase energy without avalanche degradation; 150 °C TJ max supports continuous operation near motor housing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSS8010M | Single-anode 40 V / 8 A Schottky in D-PAK; no center-tap; higher IF(AV) but lacks dual-leg topology. | Requires two devices for dual-path use; better suited for single-rail high-current outputs. | Select when needing >3.5 A per path and no shared cathode requirement. |
| SB540-E3/54 | 40 V / 5 A discrete Schottky in DO-201AD; higher VF (0.55 V @ 3 A), no MSL Level 1 rating, larger footprint. | Limited to lower-frequency (<100 kHz) designs; unsuitable for automated high-volume SMT. | Select only for cost-sensitive, non-reflow, low-frequency legacy designs. |
Compared with VSS8010M and SB540-E3/54, VS-6CWQ04FNTRPBF uniquely provides dual-anode integration with MSL Level 1 compliance and sub-0.5 V VF at elevated temperature - essential for space-constrained, high-efficiency, high-reliability power stages.

FAQ
What is the maximum average forward current rating for VS-6CWQ04FNTRPBF per leg?
The VS-6CWQ04FNTRPBF is rated for 3.5 A average forward current per leg at TC = 135 °C with 50 % duty cycle rectangular waveform. The total device rating is 7 A when both legs operate simultaneously under proper thermal management. This rating assumes use of the D-PAK thermal pad and adequate PCB copper area for heat dissipation.
Does VS-6CWQ04FNTRPBF support lead-free reflow soldering?
Yes, VS-6CWQ04FNTRPBF meets MSL Level 1 per J-STD-020 and is qualified for peak reflow temperatures up to 260 °C. Its Pb-free (PbF) construction and robust package allow standard lead-free reflow profiles without preconditioning or special handling requirements.
What does the "center-tap configuration" mean for VS-6CWQ04FNTRPBF?
The center-tap configuration of VS-6CWQ04FNTRPBF refers to its internal common-cathode structure: two independent Schottky anodes (pins 1 and 3) share one cathode terminal (pin 2). This enables dual-path rectification or freewheeling in split-rail or interleaved topologies without external wiring between cathodes.
Can VS-6CWQ04FNTRPBF replace two separate 40 V Schottky diodes?
Yes, VS-6CWQ04FNTRPBF can replace two discrete 40 V Schottky diodes in applications requiring shared cathode routing, such as dual-output flyback or center-tapped transformer rectification. It saves PCB area, reduces assembly cost, and ensures matched thermal and electrical characteristics between legs.
What is the typical junction capacitance of VS-6CWQ04FNTRPBF and why does it matter?
The VS-6CWQ04FNTRPBF has a typical junction capacitance of 189 pF per leg at 5 V reverse bias and 25 °C. This low CT value minimizes displacement current and switching loss during high-frequency turn-off, making it suitable for converters operating above 300 kHz where capacitive losses dominate.
