Product details
Overview
VS-VSUD400CW60 from Vishay Semiconductors is a dual common-cathode ultrafast soft-recovery diode module rated at 600 V reverse voltage and 400 A average forward current per leg, with 90 ns reverse recovery time and 830 nC reverse recovery charge at 25 °C. It is designed for high-frequency power converters and HF welding systems where switching loss minimization and EMI reduction are critical.
For engineers reviewing the VS-VSUD400CW60 datasheet, VS-VSUD400CW60 pinout, VS-VSUD400CW60 application, or VS-VSUD400CW60 equivalent, key selection criteria include its TO-244 package thermal resistance (0.19 °C/W per leg), soft recovery behavior eliminating snubbers in most topologies, and dual-leg configuration enabling interleaved or phase-shifted converter designs.
Technical Context
This module integrates two FRED Pt® diodes in a single TO-244 insulated-base package with common cathode connection and isolated anode lugs. Its soft reverse recovery (trr = 90 ns typ., Qrr = 830 nC) reduces voltage overshoot and RFI generation during turn-off, enabling higher switching frequencies without added snubber components.
The device operates across -40 °C to +150 °C junction temperature range, with thermal resistance of 0.095 °C/W (junction-to-case, module-level) and 0.19 °C/W (per leg), supporting high-power density industrial converter designs requiring stable conduction and low dynamic losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Industrial HF Welding Power Supply | Three-Phase Active Front-End Rectifier |
|---|---|
Use Scenario: High-duty-cycle inverter-based welding equipment operating at 20–50 kHz switching frequency with tight EMI limits. IC Role / Device Role / Timing Role: Output rectifier in secondary-side full-bridge inverter; handles 400 A peak currents with minimal turn-off ringing.

IC Role / Device Role / Timing Role: DC-link freewheeling diode in NPC (Neutral Point Clamped) inverter legs; clamps voltage during switching transitions. Use Value: 600 V VR rating matches 1000 V DC bus with 1.67× safety margin; TO-244 base insulation supports 3.5 kV isolation testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDD400-600 | Same 600 V / 400 A rating, but trr = 120 ns (typ.), Qrr = 1100 nC; TO-247-3L package with single anode tab | Lacks dual-anode isolation; unsuitable for interleaved or phase-split topologies requiring independent anode routing | Select when space-constrained single-leg rectification is needed and snubber tolerance allows higher Qrr |
| Infineon IDH04SG60C | 600 V / 400 A, trr = 85 ns, Qrr = 750 nC; TO-247-4L with Kelvin cathode sense, no common-cathode configuration | Four-terminal layout enables precise gate drive but requires separate cathode connections-no shared cathode benefit | Prefer for high-precision synchronous rectifier control where cathode sensing improves regulation accuracy |
Compared with MDD400-600 and IDH04SG60C, the VS-VSUD400CW60 uniquely delivers dual isolated anodes plus common cathode in a thermally optimized TO-244 package-making it the only choice for interleaved PFC, dual-output LLC, or phase-shifted full-bridge rectifiers requiring independent anode node routing and shared return path.

FAQ
What is the maximum continuous forward current rating for VS-VSUD400CW60 at 97 °C case temperature?
The VS-VSUD400CW60 is rated for 200 A continuous forward current per diode leg at TC = 97 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-244 package and internal bond wire capacity. Operation above this level risks accelerated degradation or thermal runaway, especially under high dIF/dt conditions.
Does VS-VSUD400CW60 require a snubber circuit in typical high-frequency converter applications?
No, the VS-VSUD400CW60 does not require a snubber circuit in most high-frequency converter applications due to its ultrafast soft recovery characteristic (trr = 90 ns, soft tail current decay). The datasheet explicitly states that the softness of recovery eliminates the need for snubbers in most cases-verified by reduced voltage overshoot and EMI in HF welding and UPS inverter testing.
What is the thermal resistance from junction to case for VS-VSUD400CW60 per leg?
The thermal resistance from junction to case for VS-VSUD400CW60 is 0.19 °C/W per leg, as confirmed in the Thermal-Mechanical Specifications table. This value applies to each individual diode leg within the dual-module structure and is measured from the silicon die to the mounting base plate surface.
Can VS-VSUD400CW60 be used in a three-phase bridge configuration?
Yes, VS-VSUD400CW60 can be used in a three-phase bridge configuration-one module per phase-with its common-cathode topology enabling simplified cathode bus routing. Each module provides two independent anode paths, allowing flexible connection to upper/lower switches while sharing a single thermal and electrical return path through the insulated base plate.
What is the reverse leakage current specification for VS-VSUD400CW60 at maximum junction temperature?
The reverse leakage current for VS-VSUD400CW60 is specified as 1.38 mA maximum at TJ = 150 °C and VR = 600 V, per the Electrical Specifications table. This value represents worst-case leakage under full-rated blocking voltage and maximum operating temperature, ensuring reliable performance in high-ambient industrial environments.
