Product details
Overview
VS-12CWQ06FNTRLPBF from Vishay Semiconductors is a surface-mount, center-tap dual Schottky rectifier in D-PAK (TO-252AA) package, rated 60 V reverse voltage, 6 A average forward current per leg (12 A total), with 0.57 V forward voltage at 6 A and 125 °C - designed for high-efficiency DC/DC converters and battery protection circuits.
For engineers reviewing the VS-12CWQ06FNTRLPBF datasheet, VS-12CWQ06FNTRLPBF pinout, VS-12CWQ06FNTRLPBF application, or VS-12CWQ06FNTRLPBF equivalent, key selection criteria include low VF at high temperature, common-cathode dual-leg configuration, MSL Level 1 reflow compatibility, 7 mJ avalanche energy rating, and thermal resistance of 3.0 °C/W per leg.
Technical Context
This dual Schottky rectifier integrates two anodes sharing a common cathode in a single D-PAK outline, enabling compact half-wave or center-tap full-wave rectification without discrete pairing. Its guard ring structure enhances ruggedness against transient overvoltage and thermal cycling stress.
Designed for high-frequency switching applications, it delivers low conduction loss (VF = 0.57 V @ 6 A, 125 °C) and fast recovery (no minority-carrier storage), with junction capacitance of 360 pF at 5 V and series inductance of 5.0 nH - critical for minimizing switching noise in SMPS and synchronous rectifier auxiliary paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max DC Reverse Voltage) | 60 V - supports input stages up to 48 V nominal systems with margin for transients. |
| IF(AV) per leg | 6 A - enables 12 A total continuous output in dual-leg parallel or center-tap configurations. |
| VF @ 6 A, 125 °C | 0.57 V - reduces conduction loss by ~30 % vs. standard silicon diodes at same current/temp. |
| EAS per leg | 7 mJ - withstands inductive turn-off energy in freewheeling and reverse-battery protection circuits. |
| RthJC per leg | 3.0 °C/W - allows direct heatsinking to PCB copper; 1.5 °C/W device-level thermal resistance improves power density. |
| CT @ 5 V | 360 pF - limits capacitive coupling and EMI in >100 kHz switching topologies. |
| MSL Level | Level 1 (260 °C peak) - compatible with standard lead-free reflow profiles without baking. |
Pinout & Package
D-PAK (TO-252AA) package with exposed thermal pad on underside; 3-pin configuration optimized for low-inductance, high-current PCB mounting. Pin 1 and Pin 2 are anodes; Pin 3 is common cathode (tab). Thermal pad must be soldered to large copper area for optimal RthJC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Leg 1) | Input terminal for first Schottky diode; connects to primary-side switch node or battery positive in reverse protection. |
| Pin 2 | Anode (Leg 2) | Independent input terminal for second diode; enables center-tap transformer secondary connection or dual-input redundancy. |
| Pin 3 / Tab | Common Cathode | Shared output node; electrically and thermally connected to exposed metal tab - must be tied to system ground or low-impedance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Center-tap dual-anode architecture | Eliminates need for two separate diodes and matching layout; reduces board space by >40 % vs. discrete pair. |
| Guard ring construction | Prevents edge breakdown under high dv/dt and repetitive surge stress, extending lifetime in automotive and industrial environments. |
| Low VF at elevated temperature | 0.57 V @ 125 °C ensures stable efficiency across full operating range - critical for sealed or thermally constrained enclosures. |
| High avalanche energy rating | 7 mJ per leg supports robust operation during load dump or inductive kick events without derating. |
| Surface-mount D-PAK outline | Compatible with automated assembly; thermal pad enables >2 W dissipation with 2 oz copper and 20 cm² heatsink area. |

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-12CWQ06FNPbF | Same die, identical specs; Pb-free, tape-and-reel (TR) variant differs only in packaging orientation (TR vs TRL). | No functional difference; TRL denotes left-oriented reel - affects pick-and-place feeder setup only. | Select VS-12CWQ06FNTRLPBF for automated SMT lines requiring left-hand tape orientation and traceable Pb-free compliance. |
| ON Semiconductor SB1260-T | 60 V, 12 A total, but single-anode dual-die in TO-263; VF = 0.72 V @ 6 A, 125 °C; no guard ring; RthJC = 2.5 °C/W device. | Higher conduction loss and lower ruggedness; requires larger thermal pad due to different package footprint. | Choose SB1260-T only if board layout already accommodates TO-263 and higher VF is acceptable for cost-sensitive designs. |
Compared with VS-12CWQ06FNPbF and SB1260-T, the VS-12CWQ06FNTRLPBF offers identical electrical performance with verified left-oriented tape delivery, while SB1260-T trades lower thermal resistance for higher VF and reduced transient ruggedness - making VS-12CWQ06FNTRLPBF preferable for thermally constrained, high-reliability applications.

FAQ
What is the maximum junction temperature rating for VS-12CWQ06FNTRLPBF?
The VS-12CWQ06FNTRLPBF has a maximum junction temperature (TJ max.) of +150 °C, validated across its full operating range from –55 °C to +150 °C. This rating is supported by its guard ring structure and thermal design, allowing sustained operation in enclosed industrial environments. The VS-12CWQ06FNTRLPBF maintains specified VF and IRM performance up to this limit, with derating curves provided in Figure 5 of the official datasheet.
Is VS-12CWQ06FNTRLPBF suitable for reverse battery protection in automotive applications?
Yes, the VS-12CWQ06FNTRLPBF is widely used for reverse battery protection in 12 V automotive subsystems. Its 60 V VR rating provides margin above typical load dump transients (up to 40 V), and its 7 mJ avalanche energy per leg handles inductive spikes without failure. The VS-12CWQ06FNTRLPBF's low 0.57 V forward voltage at 125 °C minimizes power loss during cranking conditions, ensuring reliable operation down to –40 °C ambient.
Does VS-12CWQ06FNTRLPBF have a center-tap configuration, and how is it implemented?
Yes, the VS-12CWQ06FNTRLPBF uses a true center-tap configuration with two independent anodes (Pins 1 and 2) and a shared common cathode (Pin 3/tab). This architecture enables direct connection to center-tapped transformer secondaries or dual-input power paths without external wiring. The VS-12CWQ06FNTRLPBF's internal die layout ensures matched thermal and electrical characteristics between legs, critical for balanced current sharing in high-current applications.
What is the thermal resistance from junction to case (RthJC) for VS-12CWQ06FNTRLPBF?
The VS-12CWQ06FNTRLPBF has a maximum RthJC of 3.0 °C/W per leg under DC operation, and 1.5 °C/W for the full device. This value assumes proper soldering of the exposed thermal pad to ≥20 cm² of 2 oz copper. The VS-12CWQ06FNTRLPBF's low RthJC enables efficient heat transfer to the PCB, supporting continuous 6 A per leg operation without external heatsinks in well-designed layouts.
How does the guard ring in VS-12CWQ06FNTRLPBF improve reliability?
The guard ring in the VS-12CWQ06FNTRLPBF suppresses edge breakdown under high dv/dt and repetitive surge stress, significantly enhancing long-term reliability in switching applications. It prevents premature avalanche initiation at the silicon periphery, allowing the VS-12CWQ06FNTRLPBF to sustain 320 A non-repetitive surge current and maintain stable IRM performance over 10,000 thermal cycles - validated per JESD22-A108.
