Product details
Overview
VS-12CWQ04FNTRRPBF from Vishay Semiconductors is a surface-mount, center-tap dual Schottky rectifier in D-PAK (TO-252AA) package, rated at 40 V reverse voltage, 6 A average forward current per leg (12 A total), and 0.48 V forward voltage drop at 6 A and 125 °C - designed for high-frequency switching power supplies and battery protection circuits.
For engineers reviewing the VS-12CWQ04FNTRRPBF datasheet, VS-12CWQ04FNTRRPBF pinout, VS-12CWQ04FNTRRPBF application, or VS-12CWQ04FNTRRPBF equivalent, key selection criteria include low VF at elevated temperature, common-cathode dual-leg configuration, MSL Level 1 moisture sensitivity, and avalanche energy rating of 9 mJ per leg.
Technical Context
This dual Schottky rectifier integrates two identical anode terminals sharing a single cathode terminal in a monolithic die structure, enabling synchronous freewheeling or dual-output DC/DC conversion without external interconnects. Its guard ring design enhances ruggedness against transient overvoltage and thermal stress.
The device operates across -55 °C to +150 °C junction temperature range with 3.0 °C/W thermal resistance (junction-to-case per leg), supporting high-power-density PCB layouts where thermal management relies on copper pour under the exposed cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max DC Reverse Voltage) | 40 V - supports input stages up to 36 V nominal systems with margin for ripple and transients |
| IF(AV) per leg | 6 A - enables 12 A total continuous conduction in center-tap configurations without derating |
| VF at 6 A, 125 °C | 0.48 V - reduces conduction loss by ~30% vs. standard silicon diodes in high-temp operation |
| EAS per leg | 9 mJ - withstands inductive turn-off energy in flyback or buck-boost converters without failure |
| RthJC per leg | 3.0 °C/W - allows direct thermal coupling to heatsinked PCB copper, critical for >5 W dissipation |
| CT at 5 V | 405 pF - minimizes capacitive loading in >1 MHz switching topologies |
| IRM at 125 °C | 40 mA - ensures stable reverse blocking in hot environments like automotive under-hood applications |
Pinout & Package
D-PAK (TO-252AA) package with exposed cathode thermal pad on underside; three-terminal configuration: Pin 1 (Anode A), Pin 2 (Cathode), Pin 3 (Anode B). Pin 2 is electrically and thermally connected to the large metal tab for low-inductance, low-resistance cathode return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode A | Input terminal for first Schottky leg; routed separately to enable independent control or sensing |
| Pin 2 | Common Cathode | Shared output node and primary thermal interface; must be soldered to ≥200 mm² copper pour for rated current |
| Pin 3 | Anode B | Input terminal for second Schottky leg; symmetrical to Pin 1 for balanced current sharing |
Key Features
| Feature | Design Value |
|---|---|
| Center-tap dual-anode topology | Eliminates need for external cathode tie point, reducing layout parasitics and improving current balance between legs |
| Guard ring construction | Prevents edge breakdown during repetitive avalanche events, extending lifetime in unregulated surge conditions |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak without baking, simplifying SMT assembly |
| Low series inductance (5.0 nH) | Minimizes voltage overshoot during fast di/dt transitions in synchronous rectification |
| Lead (Pb)-free and RoHS-compliant | Meets global environmental regulations without performance trade-offs in thermal or electrical behavior |
Applications
| Switching Power Supplies | Battery Charging Circuits |
|---|---|
Use Scenario: Secondary-side rectification in 24–48 V output DC/DC converters operating at 300–500 kHz. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing MOSFET drivers; common-cathode output feeds bulk capacitor bank. Use Value: 0.48 V VF at 125 °C reduces conduction loss by 1.8 W per leg vs. Si diode, directly improving efficiency above 85% at full load. | Use Scenario: Input OR-ing and reverse-polarity protection in multi-source Li-ion battery chargers (e.g., USB-C PD + wall adapter). IC Role / Device Role / Timing Role: Back-to-back configured as ideal diode controller alternative; anodes accept independent inputs, cathode delivers combined output. Use Value: 40 mA IRM at 125 °C prevents thermal runaway during hot-plug events, ensuring safe operation without active monitoring. |

IC Role / Device Role / Timing Role: Series-connected anode-to-battery, cathode-to-load; blocks reverse current while conducting forward at <0.5 V drop. Use Value: 150 °C TJ max and -55 °C minimum storage temperature ensure reliability across engine bay thermal cycles (-40 °C to +125 °C ambient). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-12CWQ04FNPbF | Same die, tube packaging (no TR suffix); identical electrical specs and thermal performance | No tape-and-reel handling; suited for low-volume prototyping or manual assembly | Select when reel feed is unnecessary and cost-sensitive small-batch builds are prioritized |
| ON Semiconductor NRVB1245CTT4G | 45 V VR, 12 A total IF(AV), but higher VF (0.72 V @ 6 A, 125 °C); TO-220AC package | Larger footprint, no MSL Level 1 rating; requires heatsink for same power level | Choose only if 45 V margin is mandatory and thermal constraints allow through-hole mounting |
Compared with VS-12CWQ04FNPbF and NRVB1245CTT4G, the VS-12CWQ04FNTRRPBF offers superior thermal integration via D-PAK's exposed cathode, lower forward drop for efficiency-critical 40 V systems, and standardized tape-and-reel delivery for automated SMT lines - making it optimal for volume production of compact, high-efficiency power stages.

FAQ
What is the maximum junction temperature rating for the VS-12CWQ04FNTRRPBF?
The VS-12CWQ04FNTRRPBF has a maximum junction temperature (TJ max.) of +150 °C, validated across its full operating range from -55 °C to +150 °C. This rating enables reliable operation in thermally demanding environments such as enclosed power supplies or automotive under-hood modules, provided thermal design meets the specified RthJC of 3.0 °C/W per leg and adequate PCB copper area is allocated beneath the cathode pad.
Does the VS-12CWQ04FNTRRPBF support lead-free reflow soldering?
Yes, the VS-12CWQ04FNTRRPBF is lead (Pb)-free and RoHS-compliant, with MSL Level 1 classification per J-STD-020. It supports peak reflow temperatures up to 260 °C without baking, making it compatible with standard lead-free SMT processes including IPC-J-STD-020-compliant profiles and no-floor-life restrictions.
How is the current rating distributed between the two anodes of the VS-12CWQ04FNTRRPBF?
The VS-12CWQ04FNTRRPBF is rated for 6 A average forward current per anode leg (Pin 1 and Pin 3), with a shared cathode (Pin 2). The total device rating is 12 A when both legs conduct simultaneously in balanced center-tap configurations - confirmed by the "2 x 6 A" designation in Vishay's official product summary and validated by thermal derating curves in Figure 5 of the datasheet.
What does the "TR" and "R" in VS-12CWQ04FNTRRPBF signify?
In VS-12CWQ04FNTRRPBF, "TR" indicates tape-and-reel packaging, and the final "R" denotes right-oriented tape orientation per Vishay's ordering convention. The "PbF" suffix confirms lead-free finish. This configuration ensures compatibility with standard pick-and-place machines using right-edge feed direction, distinguishing it from TRL (left-oriented) or tube-packaged variants like VS-12CWQ04FNPbF.
Is the VS-12CWQ04FNTRRPBF suitable for reverse battery protection in automotive applications?
Yes, the VS-12CWQ04FNTRRPBF is suitable for reverse battery protection in 12 V automotive systems. Its 40 V VR rating provides margin against jump-start transients, 150 °C TJ max supports under-hood thermal cycling, and 40 mA IRM at 125 °C ensures stable blocking without thermal runaway - all verified in Vishay's official datasheet under Electrical Specifications and Absolute Maximum Ratings sections.
