Product details
Overview
VS-VSUD410CW60 from Vishay Semiconductors is a FRED Pt® ultrafast soft recovery diode module with two common-cathode diodes in a TO-244 package, rated at 600 V reverse voltage and 400 A average forward current per leg. It delivers 215 ns typical reverse recovery time, 5100 nC typical Qrr, and 0.19 °C/W thermal resistance (junction-to-case per leg), optimized for high-frequency power converters and HF welding systems.
For engineers reviewing the VS-VSUD410CW60 datasheet, VS-VSUD410CW60 pinout, VS-VSUD410CW60 application, or VS-VSUD410CW60 equivalent, key selection criteria include soft-recovery behavior to eliminate snubbers, low conduction loss at 400 A, thermal performance under 137 °C case temperature, and mechanical compatibility with TO-244 heatsink mounting.
Technical Context
The VS-VSUD410CW60 integrates two independent ultrafast diodes sharing a common cathode terminal, enabling dual-leg rectification in three-phase or interleaved topologies without external parallel wiring. Its soft recovery characteristic suppresses voltage overshoot and ringing during turn-off, reducing EMI generation and eliminating snubber circuits in most industrial switching applications.
Designed for operation up to 175 °C junction temperature, the device sustains 397 A DC forward current at 85 °C case temperature and maintains stable VFM of 0.98–1.21 V at 400 A and 175 °C. The 5 nH series inductance and 0.095 °C/W total junction-to-case thermal resistance (module-level) support high-efficiency thermal management in compact power modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKD410-60 | Same TO-244 package and 600 V/400 A rating, but uses standard FRED (not FRED Pt®); trr = 250 ns (typ.), Qrr = 6200 nC. | Higher recovery loss limits use in >5 kHz topologies; requires snubber in high-dI/dt welder designs. | Select when cost sensitivity outweighs EMI reduction needs and thermal margin exceeds 15 °C. |
| IXYS MDD400-600 | 600 V/400 A dual-diode module in ISOPLUS247™; trr = 230 ns (typ.), Qrr = 5400 nC; RthJC = 0.22 °C/W per leg. | Larger footprint and different mounting pattern; higher thermal resistance increases heatsink sizing requirement. | Choose when existing ISOPLUS247™ board layout must be reused and softness priority is secondary to supply chain availability. |
Compared with VSKD410-60 and IXYS MDD400-600, the VS-VSUD410CW60 provides superior soft recovery (215 ns vs. ≥230 ns) and lower thermal resistance (0.19 °C/W), enabling higher switching frequencies and smaller heatsinks in space-constrained industrial power systems.

FAQ
What is the maximum continuous forward current rating for VS-VSUD410CW60 at 137 °C case temperature?
The VS-VSUD410CW60 is rated for 200 A continuous forward current per diode leg at TC = 137 °C, as specified in the Absolute Maximum Ratings table. This derated value ensures safe operation under sustained high-temperature conditions typical in enclosed industrial enclosures without active cooling. The VS-VSUD410CW60 maintains reliable conduction and thermal stability even at this elevated case temperature due to its low RthJC of 0.19 °C/W per leg.
Does VS-VSUD410CW60 require a snubber circuit in high-dI/dt applications?
No, the VS-VSUD410CW60 does not require a snubber circuit in most high-dI/dt applications due to its soft recovery characteristic-confirmed by trr = 215 ns and low Qrr = 5100 nC at TJ = 25 °C. The FRED Pt® silicon design minimizes voltage overshoot and ringing during turn-off, making it suitable for HF welding and 10–20 kHz motor drive inverters without external snubbing. The VS-VSUD410CW60 datasheet explicitly states that softness eliminates the need for snubbers in most applications.
What is the thermal resistance from junction to case for VS-VSUD410CW60, and how is it measured?
The thermal resistance from junction to case (RthJC) for VS-VSUD410CW60 is 0.19 °C/W per diode leg and 0.095 °C/W for the full module, measured under steady-state conditions with the base plate mounted to a flat, thermally conductive heatsink using specified torque (30–40 lbf·in). This value reflects the total thermal path through the die, solder, copper base, and mounting interface. The VS-VSUD410CW60 achieves this low RthJC via optimized internal construction and direct base-plate thermal coupling.
Can VS-VSUD410CW60 be used in a three-phase bridge rectifier configuration?
Yes, the VS-VSUD410CW60 can be used in a three-phase bridge rectifier configuration by pairing two units-one for the upper (anode-connected) legs and one for the lower (cathode-connected) legs-or by using its dual common-cathode topology in split-bus or interleaved arrangements. Its two independent anode terminals and shared cathode enable flexible implementation in multi-phase topologies. The VS-VSUD410CW60 mechanical layout and electrical isolation support such configurations without additional isolation hardware.
What is the mounting torque specification for the main screws of VS-VSUD410CW60?
The recommended mounting torque for the main screws of VS-VSUD410CW60 is 30–40 lbf·in (3.4–4.6 N·m), as defined in the Thermal-Mechanical Specifications table. This range ensures optimal thermal contact between the TO-244 base plate and the heatsink while preventing mechanical damage to the ceramic insulator or solder joints. The VS-VSUD410CW60 also specifies a separate center-hole torque of 12–18 lbf·in (1.4–2.1 N·m) to maintain structural integrity during thermal cycling.
