Product details
Overview
VS-6CWQ10FNTRLPBF from Vishay Semiconductors is a surface-mount, center-tap dual Schottky rectifier in D-PAK (TO-252AA) package, rated for 100 V reverse voltage, 3.5 A average forward current per leg (7 A total), and 0.63 V forward voltage at 3 A and 125 °C - optimized for high-frequency switching power supplies and battery protection circuits.
For engineers reviewing the VS-6CWQ10FNTRLPBF datasheet, VS-6CWQ10FNTRLPBF pinout, VS-6CWQ10FNTRLPBF application, or VS-6CWQ10FNTRLPBF equivalent, key selection criteria include its common-cathode configuration, low VF at elevated temperature, MSL Level 1 reflow compatibility, and 440 A non-repetitive surge rating per leg - critical for compact DC/DC converters and automotive auxiliary power modules.
Technical Context
This dual Schottky rectifier integrates two identical anode terminals sharing a single cathode terminal in a monolithic die structure, enabling synchronous freewheeling in half-bridge topologies without external interconnects. Its guard ring design enhances ruggedness against transient overvoltage and thermal cycling stress.
The device operates with junction temperatures from –40 °C to +150 °C, exhibits 92 pF typical junction capacitance per leg at 5 V reverse bias, and supports dV/dt up to 10,000 V/μs - confirming suitability for fast-switching SMPS designs where reverse recovery loss must be eliminated.

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-diode DFN5x6 package, 100 V/8 A, no center-tap; RthJC = 3.0 °C/W | Requires external cathode connection for dual-leg use; better thermal performance but higher layout complexity | Select when discrete routing of cathodes is acceptable and lower thermal resistance is prioritized over integration |
| MBR20100CT | TO-220AB package, 100 V/10 A total, higher VF (0.85 V @ 10 A, 25 °C), no MSL Level 1 rating | Through-hole mounting only; unsuitable for automated SMT lines or high-density boards | Select only for legacy through-hole designs where reflow compatibility and footprint size are not constraints |
Compared with VSS8010M and MBR20100CT, VS-6CWQ10FNTRLPBF uniquely combines center-tap integration, MSL Level 1 compliance, and D-PAK thermal performance - making it optimal for new SMT-based, space-constrained, high-reliability power modules requiring dual-leg conduction with minimal board area.

FAQ
What is the maximum junction temperature rating for VS-6CWQ10FNTRLPBF?
The VS-6CWQ10FNTRLPBF has a maximum junction temperature (TJ) of +150 °C, validated across its full operating range from –40 °C to +150 °C. This rating is confirmed in the Absolute Maximum Ratings table and supported by thermal impedance curves showing stable ZthJC behavior up to 150 °C. The VS-6CWQ10FNTRLPBF must be mounted with adequate PCB copper area to maintain TJ ≤ 150 °C under worst-case power dissipation.
Does VS-6CWQ10FNTRLPBF support lead-free reflow soldering?
Yes, VS-6CWQ10FNTRLPBF is rated MSL Level 1 per J-STD-020 and qualified for peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering processes. The "PbF" suffix explicitly denotes lead-free termination, and the device requires no pre-baking prior to assembly - a key advantage over moisture-sensitive alternatives.
What does the "W" in the VS-6CWQ10FNTRLPBF part number indicate?
In the VS-6CWQ10FNTRLPBF ordering code, the "W" denotes the D-PAK package variant (TO-252AA). This is defined in Vishay's official part marking documentation (doc# 95059), where "W" is the standardized package identifier for the D-PAK outline - distinct from "S" (SO-8) or "D" (D2PAK) variants within the same Q-series family.
Is VS-6CWQ10FNTRLPBF suitable for reverse battery protection?
Yes, VS-6CWQ10FNTRLPBF is widely deployed in reverse battery protection due to its common-cathode configuration and 100 V blocking capability. When oriented with cathodes tied to system ground and anodes to battery inputs, it blocks reverse polarity while conducting forward current with only 0.63 V drop at 3 A and 125 °C - minimizing voltage loss in critical 12 V automotive subsystems.
What is the thermal resistance from junction to case (RthJC) for VS-6CWQ10FNTRLPBF?
The VS-6CWQ10FNTRLPBF has a maximum RthJC of 4.70 °C/W per leg under DC operation, as specified in the Thermal-Mechanical Specifications table. This value assumes proper soldering of the exposed thermal pad to a minimum 100 mm² copper area on the PCB. The total device RthJC is 2.35 °C/W since both legs share the same case interface.
