Product details
Overview
VS-209CNQ150PBF from Vishay Semiconductors is a high-current center-tap Schottky rectifier module rated for 200 A average forward current, 150 V maximum DC reverse voltage, and operation up to 175 °C junction temperature. It features two common-cathode diodes in a TO-244 package with lug terminals, optimized for low forward voltage (0.71 V at 100 A, 125 °C) and low reverse leakage at elevated temperatures - used in industrial UPS systems, welding power supplies, and high-current DC-DC converters.
For engineers reviewing the VS-209CNQ150PBF datasheet, VS-209CNQ150PBF pinout, VS-209CNQ150PBF application, or VS-209CNQ150PBF equivalent, key selection criteria include its 175 °C thermal rating, dual-leg common-cathode configuration, 0.38 °C/W thermal resistance per leg, 10 kA non-repetitive surge capability, and UL E222165 approval - critical for ruggedized industrial power conversion designs.
Technical Context
The VS-209CNQ150PBF implements a center-tap Schottky architecture with two anode terminals sharing a single cathode baseplate, enabling synchronous rectification or dual-phase freewheeling in high-efficiency topologies. Its proprietary barrier technology suppresses reverse leakage at 125–175 °C, supporting stable operation where conventional silicon diodes fail.
Thermally, it uses a copper baseplate with direct-mount lug terminals and achieves 0.19 °C/W total thermal resistance (junction-to-heatsink), validated under 50% duty cycle rectangular waveforms at TC = 131 °C. The 7.0 nH typical series inductance and 10,000 V/μs dV/dt rating support high-frequency switching up to several hundred kHz without oscillation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKD100-16 | 160 V VRRM, 100 A IF(AV) per leg, TO-247AC package, no center tap | Requires two separate devices for dual-leg function; lower surge rating (6 kA) | Preferred when space permits discrete mounting and lower voltage rating suffices |
| IXYS DSSK100-015A | 150 V VRRM, 100 A IF(AV) per leg, dual common-cathode in SOT-227B, RthJC = 0.45 °C/W | Lower thermal performance and 100 A total rating vs. 200 A; not UL recognized | Used where footprint constraints outweigh thermal or certification requirements |
Compared with VS-209CNQ150PBF, VSKD100-16 offers higher surge robustness per unit area but lacks integrated center-tap functionality, while DSSK100-015A provides compact packaging at the expense of thermal margin and safety certification - making VS-209CNQ150PBF optimal for thermally demanding, certified industrial systems.

FAQ
What is the maximum junction temperature rating for VS-209CNQ150PBF?
The VS-209CNQ150PBF is rated for continuous operation up to +175 °C junction temperature, verified per Vishay's industrial qualification standards. This rating enables deployment in sealed cabinets or high-ambient environments where conventional 150 °C-rated diodes would require significant derating. The VS-209CNQ150PBF maintains specified VF and IR performance across this full range, confirmed in thermal characterization curves (Fig. 2 and Fig. 5 of Doc. 94156).
Does VS-209CNQ150PBF support center-tap transformer configurations?
Yes, the VS-209CNQ150PBF integrates two Schottky diodes with a shared cathode baseplate, forming a true center-tap rectifier topology. Its Anode 1 and Anode 2 terminals connect directly to opposite ends of a center-tapped secondary winding, while the cathode serves as the common DC output. This eliminates the need for external paralleling or discrete dual-diode assemblies - a core design feature confirmed in the "Circuit configuration" section of the datasheet.
What is the thermal resistance from junction to case for VS-209CNQ150PBF?
The VS-209CNQ150PBF has a thermal resistance of 0.38 °C/W per leg (junction-to-case), and 0.19 °C/W for the full module (junction-to-heatsink when properly mounted). These values are measured under standardized conditions per JESD51-14 and are critical for calculating allowable power dissipation - for example, at 175 °C max TJ and 85 °C heatsink temperature, each leg can dissipate up to 237 W continuously. This data appears in the Thermal-Mechanical Specifications table of Doc. 94156.
Is VS-209CNQ150PBF UL recognized, and what is the file number?
Yes, the VS-209CNQ150PBF is UL recognized under file E222165, as explicitly stated in the Features section of the official Vishay datasheet (Doc. 94156). This recognition covers flammability, dielectric strength, and construction requirements for end-equipment safety certification in North America. No additional agency documentation is required to claim UL compliance for this specific part number.
What is the forward voltage drop of VS-209CNQ150PBF at 100 A and 125 °C?
The VS-209CNQ150PBF exhibits a maximum forward voltage drop of 0.71 V per leg at 100 A and TJ = 125 °C, as specified in the Electrical Specifications table (Doc. 94156, page 2). This value is measured under pulsed conditions to avoid self-heating artifacts and reflects real-world conduction loss in high-temperature industrial operation - significantly lower than silicon diodes and critical for efficiency-critical applications like welding and plating.
