Product details
Overview
VS-6CWQ06FNTRRPBF from Vishay Semiconductors is a surface-mount, dual-leg Schottky rectifier in D-PAK (TO-252AA) package with common cathode configuration, rated for 60 V reverse voltage and 3.5 A average forward current per leg (7 A total device), featuring low 0.61 V forward voltage at 3 A and 25 °C - used in DC/DC converters, battery charging circuits, and reverse polarity protection.
For engineers reviewing the VS-6CWQ06FNTRRPBF datasheet, VS-6CWQ06FNTRRPBF pinout, VS-6CWQ06FNTRRPBF application, or VS-6CWQ06FNTRRPBF equivalent, key selection criteria include its center-tap common-cathode topology, 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-anode Schottky rectifier integrates two independent 3.5 A legs sharing a single cathode terminal, enabling compact half-wave or synchronous rectification in space-constrained power stages. Its guard-ringed die structure supports rugged operation up to 150 °C junction temperature and withstands 490 A non-repetitive surge current (5 μs sine).
The device delivers high-frequency switching performance with 145 pF typical junction capacitance per leg at 5 V and 10,000 V/μs maximum dV/dt rating. Its low forward slope resistance (34.31 mΩ) and threshold voltage (0.38 V at max TJ) minimize conduction losses in 12–48 V input systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Package | D-PAK (TO-252AA) - surface-mount outline with exposed thermal pad for PCB heat sinking |
| IF(AV) per leg | 3.5 A - continuous DC or rectangular waveform current per anode leg at TC = 133 °C |
| VRRM | 60 V - maximum repetitive reverse voltage; defines safe blocking range in buck/flyback outputs |
| VF @ 3 A, 25 °C | 0.61 V - low conduction loss enabling >92 % efficiency in 5–12 V output converters |

Pinout & Package
D-PAK (TO-252AA) package with three terminals: two anodes (pins 1 and 2) and one common cathode (pin 3). Exposed copper thermal pad (pin 4) is electrically connected to cathode and must be soldered to PCB ground plane for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode Leg A | Input path for first Schottky diode; connects to primary-side switch node or transformer winding |
| 2 | Anode Leg B | Input path for second Schottky diode; enables dual-input or interleaved rectification |
| 3 | Common Cathode | Shared output node; ties both legs to DC output rail or filter capacitor negative |
| 4 | Thermal Pad | Electrically tied to cathode; requires minimum 100 mm² copper pour for thermal compliance |
Key Features
| Feature | Design Value |
|---|---|
| Center-tap common cathode | Enables dual-anode rectification with single output node - reduces PCB routing complexity vs. discrete diodes |
| Guard ring structure | Prevents edge breakdown under high dv/dt or mechanical stress - extends lifetime in automotive transients |
| MSL Level 1 rating | Supports standard 260 °C peak reflow without preconditioning - eliminates moisture sensitivity handling overhead |
| Low VF temperature coefficient | VF drops to 0.53 V at 125 °C (3 A) - improves thermal stability vs. silicon diodes with positive TC |
| RoHS-compliant Pb-free finish | Meets EU Directive 2002/95/EC and JEDEC J-STD-020 - qualified for industrial and consumer production |
Applications

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; higher VF (0.72 V @ 3 A) and lower EAS (4.5 mJ) | Limited surge robustness in motor drive freewheeling; acceptable for low-power SMPS | Select when cost sensitivity outweighs 12 % higher conduction loss and reduced avalanche margin |
| MBR660CT | TO-220AB package, 60 V, 3 A per leg; no MSL Level 1 rating; VF = 0.75 V @ 3 A | Requires through-hole assembly and heatsink mounting - unsuitable for high-density SMT designs | Choose only for legacy through-hole platforms where D-PAK footprint is unavailable |
Compared with STPS640CW and MBR660CT, VS-6CWQ06FNTRRPBF provides superior thermal performance (4.70 °C/W vs. ≥6.5 °C/W), lower forward drop, and guaranteed lead-free reflow compatibility - making it optimal for new SMT power designs demanding reliability and efficiency.

FAQ
What is the maximum junction temperature rating for the VS-6CWQ06FNTRRPBF?
The VS-6CWQ06FNTRRPBF has a maximum junction temperature (TJ max.) of 150 °C, verified per absolute maximum ratings in Vishay document 94249. This rating applies under steady-state conditions with proper PCB thermal management - specifically, a minimum 100 mm² copper pour connected to the exposed thermal pad (pin 4) and maintained at ≤133 °C case temperature for full 3.5 A per leg operation.
Is the VS-6CWQ06FNTRRPBF pin-compatible with other D-PAK dual Schottky rectifiers?
The VS-6CWQ06FNTRRPBF uses standard D-PAK (TO-252AA) pinout: pins 1 and 2 are anodes, pin 3 is common cathode, and pin 4 is the thermal pad tied to cathode. It matches JEDEC outline TO-252AA and shares identical land pattern dimensions with STPS640CW and MBR660CT - however, electrical differences (e.g., VF, EAS, RthJC) require validation before substitution in existing designs.
Does the VS-6CWQ06FNTRRPBF support lead-free reflow soldering?
Yes, the VS-6CWQ06FNTRRPBF is RoHS-compliant and rated MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. Its Pb-free finish and thermal design allow direct integration into standard lead-free SMT processes without pre-baking or special handling - confirmed in Vishay document 94249 revision 14-Jan-11.
What is the avalanche energy rating of the VS-6CWQ06FNTRRPBF, and how is it tested?
The VS-6CWQ06FNTRRPBF has a non-repetitive avalanche energy rating (EAS) of 6 mJ per leg, measured at TJ = 25 °C with IAS = 1 A and L = 12 mH (per document 94249). This rating reflects single-pulse robustness against inductive switching transients and is validated using standardized avalanche test circuits - not intended for repetitive operation.
How does the forward voltage of the VS-6CWQ06FNTRRPBF vary with temperature?
The VS-6CWQ06FNTRRPBF exhibits a negative temperature coefficient for forward voltage: VF drops from 0.61 V at 25 °C to 0.53 V at 125 °C (both at 3 A per leg), as shown in the electrical specifications table. This behavior improves thermal stability in high-temperature environments and reduces conduction loss drift during sustained load operation.
