Product details
Overview
VS-6CWQ06FNTRLPBF from Vishay Semiconductors is a surface-mount, center-tap dual Schottky rectifier in D-PAK (TO-252AA) package, rated 60 V reverse voltage and 3.5 A average forward current per leg (7 A total device), with low 0.61 V forward voltage at 3 A and 25 °C, used for high-frequency freewheeling and reverse battery protection in DC/DC converters and switching power supplies.
For engineers reviewing the VS-6CWQ06FNTRLPBF datasheet, VS-6CWQ06FNTRLPBF pinout, VS-6CWQ06FNTRLPBF application, or VS-6CWQ06FNTRLPBF equivalent, key selection criteria include its common-cathode dual-leg configuration, 4.70 °C/W junction-to-case thermal resistance per leg, 6 mJ non-repetitive avalanche energy rating, and RoHS-compliant, MSL Level 1 reflow capability.
Technical Context
This dual Schottky rectifier integrates two identical anode terminals sharing a single cathode terminal in a monolithic die structure, enabling synchronous half-wave rectification in center-tapped topologies. Its guard ring design enhances ruggedness against transient overvoltage and thermal stress, supporting reliable operation up to 150 °C junction temperature.
The device operates with low forward voltage drop across its wide temperature range (–40 °C to 150 °C), and exhibits fast recovery characteristics due to absence of minority-carrier storage-confirmed by 10,000 V/μs maximum dV/dt rating and 145 pF typical junction capacitance per leg at 5 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max DC Reverse Voltage) | 60 V - supports input rails up to 48 V nominal systems with margin for transients |
| IF(AV) per leg | 3.5 A - enables continuous conduction mode operation in compact 12–24 V DC/DC converters |
| VF at 3 A, 25 °C | 0.61 V - reduces forward conduction loss to ~1.83 W per leg, easing thermal management |
| RthJC per leg | 4.70 °C/W - allows direct PCB copper pour heatsinking without external heatsink for ≤2.5 W dissipation |
| EAS per leg | 6 mJ - withstands inductive turn-off energy in flyback and buck-boost freewheeling paths |
| CT per leg @ 5 V | 145 pF - minimizes capacitive loading on high-side switch nodes in synchronous rectifier designs |
| IRM @ 125 °C | 30 mA - ensures stable blocking under elevated ambient conditions in enclosed power modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS640CW | Same D-PAK package, 60 V, 3 A per leg (6 A total); VF = 0.65 V @ 3 A, 25 °C; RthJC = 5.5 °C/W per leg | Lower current rating limits use in >5 A continuous output designs; higher thermal resistance requires larger copper area | Select when cost sensitivity outweighs marginal efficiency gain and board space permits additional thermal relief |
| MBR1060CT | TO-220AB package, 60 V, 5 A per leg (10 A total); VF = 0.75 V @ 5 A, 25 °C; no MSL rating | Through-hole mounting incompatible with automated SMT lines; lacks RoHS-compliant reflow profile support | Choose only for legacy through-hole designs or prototyping where thermal mass mitigates peak dissipation |
Compared with STPS640CW and MBR1060CT, the VS-6CWQ06FNTRLPBF delivers superior thermal performance (4.70 vs. 5.5 °C/W), tighter VF matching across legs, and full SMT manufacturability-making it optimal for high-density, high-efficiency 3–7 A DC/DC modules targeting automotive and industrial markets.

FAQ
What is the maximum average forward current rating per leg for VS-6CWQ06FNTRLPBF?
The VS-6CWQ06FNTRLPBF is rated for 3.5 A average forward current per leg at TC = 133 °C with 50 % duty cycle rectangular waveform. This corresponds to 7 A total device current. Derating is required above 133 °C case temperature, as shown in Figure 5 of the datasheet. The VS-6CWQ06FNTRLPBF maintains this rating under MSL Level 1 reflow conditions and supports sustained operation up to 150 °C junction temperature.
Does VS-6CWQ06FNTRLPBF support lead-free reflow assembly?
Yes, the VS-6CWQ06FNTRLPBF is RoHS-compliant and qualified for lead-free reflow with a maximum peak temperature of 260 °C, meeting MSL Level 1 per J-STD-020. Its PbF marking confirms lead-free terminations and compatibility with standard industry reflow profiles. No pre-baking is required prior to assembly, and the VS-6CWQ06FNTRLPBF retains full electrical specifications after reflow.
What is the pin configuration and thermal pad connection for VS-6CWQ06FNTRLPBF?
The VS-6CWQ06FNTRLPBF uses a 4-pin D-PAK (TO-252AA) outline: Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2, Pin 4 = Exposed Thermal Pad. The thermal pad is electrically tied to the cathode (Pin 2) and must be soldered to a large PCB copper area for thermal conduction and EMI control. The VS-6CWQ06FNTRLPBF datasheet specifies minimum pad dimensions and solder stencil guidelines in Document 95016.
How does the guard ring feature improve reliability of VS-6CWQ06FNTRLPBF?
The guard ring in the VS-6CWQ06FNTRLPBF enhances edge termination robustness, suppressing surface leakage and preventing premature breakdown under high dv/dt or transient overvoltage conditions. This design improves long-term reliability in harsh environments such as automotive load-dump events or industrial motor drive freewheeling paths. The VS-6CWQ06FNTRLPBF demonstrates stable IRM and EAS performance across its full temperature range thanks to this structural reinforcement.
Can VS-6CWQ06FNTRLPBF replace discrete Schottky diodes in center-tapped transformer designs?
Yes, the VS-6CWQ06FNTRLPBF is specifically designed as a drop-in replacement for two discrete Schottky diodes in center-tapped configurations-its common-cathode topology eliminates separate cathode routing and reduces parasitic inductance. Unlike discrete solutions, the VS-6CWQ06FNTRLPBF ensures matched VF and thermal coupling between legs, improving current sharing and system efficiency. It is widely deployed in telecom and server power supplies for this purpose.
