Product details
Overview
VS-VSUD405CW60 from Vishay Semiconductors is a dual common-cathode ultrafast soft-recovery diode module rated for 400 A average forward current and 600 V reverse voltage, featuring 124 ns typical reverse recovery time and 1466 nC typical reverse recovery charge at 25 °C. It is designed for high-frequency power converters, HF welding inverters, and industrial UPS systems where switching loss reduction and EMI suppression are critical.
For engineers reviewing the VS-VSUD405CW60 datasheet, VS-VSUD405CW60 pinout, VS-VSUD405CW60 application, or VS-VSUD405CW60 equivalent, key selection criteria include its TO-244 package with wire-bondable terminals, two-diode common-cathode configuration, thermal resistance of 0.095 °C/W (module), and soft recovery behavior eliminating snubbers in most topologies.
Technical Context
This device integrates two FRED Pt® diodes in a single TO-244 baseplate-mounted module with shared cathode connection and isolated anode terminals. Its soft recovery waveform minimizes voltage overshoot and ringing during commutation, directly reducing RFI generation and enabling higher switching frequencies without added filtering.
The module supports continuous per-diode forward current up to 480 A at 25 °C case temperature and delivers low forward voltage drop - 1.13 V typ. at 200 A and 1.27 V typ. at 400 A - while maintaining robust thermal performance via 0.19 °C/W junction-to-case resistance per diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 400 A average forward current per diode - defines continuous DC or low-duty-cycle RMS current handling in rectifier legs |
| VR | 600 V reverse voltage rating - maximum repetitive blocking voltage per diode under operating conditions |
| trr (typ.) | 124 ns at TJ = 25 °C, IF = 50 A, dIF/dt = 500 A/μs - determines minimum dead-time requirements in bridge topologies |
| Qrr (typ.) | 1466 nC at TJ = 25 °C - quantifies stored charge removed during turn-off; impacts switching loss and snubber sizing |
| RthJC (module) | 0.095 °C/W - thermal resistance from junction to case for the full module, critical for heatsink design and derating |
| VFM (typ.) | 1.27 V at IF = 400 A, TJ = 25 °C - forward conduction loss contributor affecting efficiency and thermal management |
| LS | 5 nH - series inductance from terminal hole to mounting plane, influencing high-di/dt transient response |
Pinout & Package
VS-VSUD405CW60 is housed in a TO-244 package: insulated metal baseplate with two anode terminals (anode 1 and anode 2) and a shared cathode baseplate connection. Mounting uses four M6 screws (center hole M8), with specified torque ranges for mechanical reliability and thermal interface integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode leg | Carries forward current into diode 1; electrically isolated from Anode 2 and baseplate |
| Anode 2 | Input terminal for second diode leg | Carries forward current into diode 2; electrically isolated from Anode 1 and baseplate |
| Baseplate (cathode) | Common cathode node for both diodes | Serves as return path for both legs; thermally coupled to heatsink and electrically referenced as system cathode |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr = 124 ns with controlled IRRM peak (24 A typ.) - reduces voltage spikes and EMI without external snubbers |
| FRED Pt® technology | Optimized lifetime control and carrier recombination - enables stable Qrr and trr across temperature and current |
| TO-244 wire-bondable construction | Robust copper baseplate with solderable or bolt-down mounting - ensures low-inductance, high-current interconnect and repeatable thermal contact |
| Industrial-level qualification | Rated for TJ = -40 to +175 °C operation with UL file E222165 - suitable for harsh environments including welding and motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKD40-06 | Same TO-244 package, 400 A/600 V, but trr = 150 ns (typ.), Qrr = 1700 nC (typ.) - slower recovery with higher stored charge | Less effective EMI suppression; may require snubber in >30 kHz designs | Acceptable where cost sensitivity outweighs EMI or efficiency targets |
| IXYS MDD400-60 | TO-244, 400 A/600 V, trr = 110 ns (typ.), Qrr = 1250 nC (typ.) - faster recovery but lower TJ max (150 °C vs. 175 °C) | Limited high-temperature operation in sealed enclosures or ambient >85 °C | Preferred for highest-frequency PFC where thermal margin is sufficient |
Compared with VSKD40-06 and IXYS MDD400-60, VS-VSUD405CW60 offers the best balance of soft recovery (reducing voltage stress), 175 °C junction rating (enabling smaller heatsinks), and proven industrial qualification - making it optimal for mission-critical welding and UPS systems.

FAQ
What is the maximum allowable case temperature for continuous operation of VS-VSUD405CW60?
The VS-VSUD405CW60 supports continuous operation up to 132 °C case temperature at 200 A IF(AV) per diode, as defined in the Absolute Maximum Ratings table. At 85 °C case temperature, it delivers 338 A per diode, and derates linearly to zero at 132 °C. This thermal profile is validated per Vishay Document Number 94687, Revision 06-Jul-2023.
Does VS-VSUD405CW60 require a snubber circuit in typical high-frequency rectifier applications?
No, the VS-VSUD405CW60 does not require a snubber in most high-frequency rectifier applications due to its soft recovery characteristic - confirmed by its low IRRM (24 A typ.) and controlled trr/Qrr ratio. Vishay explicitly states that the softness eliminates snubbers in "most applications," including HF welding and power converters, as documented in the DESCRIPTION/APPLICATIONS section of datasheet 94687.
What is the thermal resistance from junction to heatsink for VS-VSUD405CW60?
The total thermal resistance from junction to heatsink for VS-VSUD405CW60 is the sum of RthJC (0.095 °C/W module) and RthCS (0.10 °C/W typ.). Therefore, the combined junction-to-heatsink resistance is approximately 0.195 °C/W under typical mounting conditions with thermal interface material, enabling accurate heatsink sizing for target junction temperature limits.
Is VS-VSUD405CW60 UL certified, and what is its certification file number?
Yes, VS-VSUD405CW60 is UL recognized under file E222165, as stated in the FEATURES section of its official datasheet (Document Number 94687). This certification covers the device's construction, materials, and safety compliance for use in industrial equipment operating within its rated voltage and temperature specifications.
How is the TO-244 package of VS-VSUD405CW60 mounted, and what are the torque specifications?
The VS-VSUD405CW60 TO-244 package is mounted using four peripheral M6 screws and one center M8 screw. Per Vishay specification, peripheral terminal torque is 30–40 lbf·in (3.4–4.6 N·m), center hole torque is 12–18 lbf·in (1.4–2.1 N·m), and vertical pull strength is rated to 80 lbf·in - ensuring mechanical stability and consistent thermal contact under vibration and thermal cycling.
