Product details
Overview
VS-200CNQ045PBF from Vishay Semiconductors is a high-current center-tap Schottky rectifier module rated for 200 A average forward current and 45 V reverse voltage, featuring dual common-cathode diodes in a TO-244 package with lug terminals. It operates up to 150 °C junction temperature and delivers low forward voltage drop (0.52 V at 100 A, 125 °C) for high-efficiency power conversion in industrial UPS and welding systems.
For engineers reviewing the VS-200CNQ045PBF datasheet, VS-200CNQ045PBF pinout, VS-200CNQ045PBF application, or VS-200CNQ045PBF equivalent, key selection criteria include its 26 kA non-repetitive surge rating, 0.38 °C/W thermal resistance per leg, 5200 pF junction capacitance, rugged guard-ring construction, and UL E222165 approval - all critical for high-reliability, high-temperature rectification.
Technical Context
This device integrates two Schottky diodes in a common-cathode configuration within a single TO-244 metal package, enabling symmetrical high-current freewheeling or dual-phase rectification without external interconnection. Its proprietary barrier technology minimizes reverse leakage at elevated temperatures, supporting stable operation up to 150 °C TJ while maintaining low VF and high dV/dt immunity (10,000 V/μs).
The module uses direct copper baseplate mounting with two anode lugs and one shared cathode base, optimized for low-inductance (7.0 nH per leg) and low-thermal-resistance (0.19 °C/W module RthJC) power delivery. It is qualified for industrial-level reliability and features guard-ring protection against edge breakdown under repetitive avalanche stress (20 A IAR, 135 mJ EAS per leg).

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 |
|---|---|---|---|
| VSKD200-04 | Same 200 A / 45 V rating, TO-247AC package with single-anode/single-cathode; no center-tap configuration | Requires external parallel connection for dual-leg use; higher thermal resistance (0.45 °C/W) | Select when discrete layout control or legacy TO-247 footprint is required |
| IXYS DSSK2X101-04A | 2 × 100 A common-cathode Schottky in SOT-227B; VF = 0.62 V @ 100 A, 125 °C; RthJC = 0.40 °C/W | Lower surge rating (12 kA), not UL-recognized; smaller footprint but lower mechanical robustness | Select when space-constrained PCB mounting is prioritized over lug-terminal ruggedness |
Compared with VS-200CNQ045PBF, VSKD200-04 lacks integrated center-tap symmetry and requires external wiring for dual-leg operation, while DSSK2X101-04A trades mechanical durability and surge immunity for compactness - making VS-200CNQ045PBF optimal for high-reliability, high-surge, lug-connected industrial rectification.

FAQ
What is the maximum junction temperature rating for VS-200CNQ045PBF?
The VS-200CNQ045PBF is rated for a maximum junction temperature of +150 °C, validated across its full operating range and confirmed in thermal derating curves (Fig. 5). This allows uninterrupted 200 A operation at case temperatures up to 116 °C under 50 % duty cycle rectangular waveform conditions. The device maintains specified VF and IR performance throughout this range, making VS-200CNQ045PBF suitable for sealed enclosures and high-ambient industrial environments without active cooling.
Does VS-200CNQ045PBF support UL safety certification?
Yes, VS-200CNQ045PBF is UL recognized under file E222165, confirming compliance with UL 60950-1 and UL 62368-1 for use in information technology and audio/video equipment. This certification covers flammability, dielectric strength, and creepage/clearance requirements for the TO-244 package. Engineers specifying VS-200CNQ045PBF in North American industrial end products can leverage this listing to streamline final system safety approvals.
What is the thermal resistance from junction to case for VS-200CNQ045PBF?
The thermal resistance from junction to case (RthJC) for VS-200CNQ045PBF is 0.38 °C/W per leg and 0.19 °C/W for the full module, as measured from each die to the shared baseplate. This low value results from direct copper-to-baseplate bonding and optimized internal thermal paths. When mounted to a heatsink with proper torque (35.4–53.1 lbf·in), VS-200CNQ045PBF achieves efficient heat extraction essential for sustained 200 A operation.
How does the guard ring in VS-200CNQ045PBF improve reliability?
The guard ring in VS-200CNQ045PBF is a diffused semiconductor structure surrounding the active junction edge, suppressing electric field crowding during high-voltage reverse bias and rapid dv/dt transitions. This prevents premature edge breakdown and enhances long-term ruggedness under repetitive surge and thermal cycling. In real-world use, this feature directly contributes to the device's qualification for industrial-level reliability and its ability to sustain 26,000 A surge events without degradation - a key differentiator of VS-200CNQ045PBF over standard Schottky modules.
Can VS-200CNQ045PBF be used in reverse battery protection circuits?
Yes, VS-200CNQ045PBF is suitable for reverse battery protection in 48 V systems due to its 45 V VR rating, low 0.52 V forward drop at 100 A/125 °C, and only 800 mA reverse leakage at 125 °C. Its common-cathode configuration allows series placement in the positive rail with both anodes tied to battery and load sides. The rugged TO-244 package and UL recognition further support use in automotive-adjacent industrial vehicles where hot-swap and jump-start transients occur - making VS-200CNQ045PBF a robust, low-loss solution for this function.
