Product details
Overview
VS-VS5HD480CW60 from Vishay Semiconductors is a FRED Pt® Gen 5 ultrafast rectifier diode module rated at 600 V, 480 A average forward current per leg, with 61 ns reverse recovery time and 525 nC typical reverse recovery charge. It features a two-diode common-cathode configuration in a TO-244 package, optimized for soft-switched and medium-frequency hard-switched power converters.
For engineers reviewing the VS-VS5HD480CW60 datasheet, VS-VS5HD480CW60 pinout, VS-VS5HD480CW60 application, or VS-VS5HD480CW60 equivalent, key selection criteria include its 175 °C maximum junction temperature, low Qrr/VF trade-off, dual-anode lug terminals, and thermal resistance of 0.095 °C/W (per module) - critical for high-power industrial and welding systems requiring minimal switching loss and robust thermal management.
Technical Context
This device integrates two independent ultrafast silicon diodes in a single base-isolated TO-244 module with common cathode connection. Its Gen 5 FRED Pt® process delivers tightly controlled trr and Qrr across temperature, enabling stable operation up to 175 °C junction temperature while maintaining <1.7 V forward voltage at 480 A and 25 °C.
The module supports high dIF/dt conditions (up to 200 A/μs), exhibits 5 nH series inductance, and achieves 1.2 nF junction capacitance per leg at 5 V - characteristics essential for minimizing voltage overshoot and EMI in resonant LLC and phase-shifted full-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 600 V - blocking voltage rating defines maximum DC or peak AC reverse bias before breakdown |
| IF(AV) per leg | 480 A at TC = 92 °C - continuous conduction capability under heatsink-limited thermal conditions |
| trr | 61 ns at TJ = 25 °C - determines minimum dead-time and switching frequency ceiling in hard-switched converters |
| Qrr (typ) | 525 nC at TJ = 25 °C - directly impacts turn-on losses in synchronous rectification and snubber design |
| RthJC (module) | 0.095 °C/W - enables ~326 W dissipation at TC = 113 °C, supporting compact heatsink integration |
| VFM @ 480 A | 1.69 V (typ) at TJ = 25 °C - sets conduction loss baseline for efficiency calculation at full-rated current |
| TJ max | 175 °C - allows operation in high-ambient environments without derating below 125 °C ambient |
Pinout & Package
VS-VS5HD480CW60 is housed in a TO-244 metal-can package with base-isolated common cathode and two insulated lug terminals for anode connections. Mounting uses ¼"-20 UNC threaded holes and specified torque (30–40 lbf·in).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Anode 2 lug | Anode of diode leg 2 | Independent high-current input terminal for second rectifier path; enables dual-phase or interleaved rectification |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 61 ns trr and 525 nC Qrr enable >100 kHz operation in ZVS/ZCS topologies without excessive turn-on loss |
| Low VF/Qrr trade-off | 1.69 V @ 480 A / 525 nC ratio reduces total power loss vs. legacy FREDs in high-duty-cycle applications |
| 175 °C junction rating | Extends usable lifetime and reliability in enclosed industrial enclosures where ambient exceeds 85 °C |

Applications
| Industrial HF Welding Power Supply | Resonant LLC Server PSU Rectification |
|---|---|
Use Scenario: High-current, medium-frequency (20–100 kHz) secondary-side rectification in capacitor-discharge and inverter-based welding machines. IC Role / Device Role / Timing Role: Dual-leg ultrafast rectifier providing synchronized conduction during high-dI/dt current pulses with minimal reverse recovery energy. Use Value: 61 ns trr and 525 nC Qrr reduce snubbing requirements and RFI generation, enabling smaller filter components and meeting CISPR-11 Class A emissions limits. |
Use Scenario: Secondary-side synchronous rectification in 3–6 kW telecom/server PSUs using LLC resonant topology. IC Role / Device Role / Timing Role: Common-cathode dual-diode module replacing discrete MOSFETs or Schottkys in center-tapped transformer outputs. Use Value: 0.095 °C/W RthJC and 175 °C TJ rating allow sustained 480 A conduction without thermal throttling in high-density 1U chassis. |
| Medium-Frequency Induction Heating | Renewable Energy Grid-Tie Inverter |
Use Scenario: DC-link rectification in 10–50 kHz induction heating inverters driving parallel-loaded resonant tanks. IC Role / Device Role / Timing Role: High-current freewheeling and commutation diode handling repetitive 2200 A IFSM peaks during zero-voltage switching transitions. Use Value: Optimized Qrr minimizes tail current during forced commutation, reducing IGBT stress and improving system efficiency by ≥0.8% at full load. |
Use Scenario: Boost-stage output rectification in 15–25 kW solar string inverters operating at 16–20 kHz PWM frequencies. IC Role / Device Role / Timing Role: Dual-leg module performing bidirectional rectification in interleaved boost stages with shared thermal interface. Use Value: Two independent anode lugs simplify PCB layout for parallel boost phases; 1.69 V VF at 480 A lowers conduction loss by 12 W vs. Gen 4 equivalents at 75 °C heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKD480-60 | Same 600 V / 480 A rating but Gen 4 FRED; trr = 75 ns, Qrr = 680 nC, RthJC = 0.11 °C/W | Higher switching loss; suitable only where <100 kHz operation is not required | Select when cost sensitivity outweighs efficiency targets and thermal margin is ≥15 °C |
| IXYS MDD480-60 | 600 V / 480 A, TO-244, but standard ultrafast (not FRED Pt®); trr = 95 ns, VF = 1.85 V @ 480 A | Lower thermal performance (RthJC = 0.13 °C/W) and higher conduction loss limit use in compact enclosures | Prefer for legacy designs already qualified with IXYS footprint; avoid in new high-efficiency welder or server PSU designs |
Compared with VSKD480-60 and IXYS MDD480-60, VS-VS5HD480CW60 delivers the lowest combined conduction and switching loss due to its Gen 5 FRED Pt® process, enabling higher power density and cooler operation - especially critical in space-constrained, air-cooled industrial systems where thermal headroom is ≤10 °C.

FAQ
What is the maximum continuous forward current rating for VS-VS5HD480CW60?
The VS-VS5HD480CW60 has an IF(AV) rating of 480 A per diode leg at TC = 92 °C. At TC = 113 °C, the rating derates to 240 A per leg. This value is defined under DC or low-duty-cycle conditions with proper heatsinking and is confirmed in the Absolute Maximum Ratings table of Document Number 96924.
Does VS-VS5HD480CW60 support common-cathode configurations?
Yes, VS-VS5HD480CW60 is explicitly configured as a two-diode common-cathode module (circuit code "C"). The base plate serves as the shared cathode node, while Anode 1 and Anode 2 are brought out via separate insulated lug terminals - enabling dual-phase rectification or interleaved converter topologies without external wiring.
What is the thermal resistance from junction to case for VS-VS5HD480CW60?
The thermal resistance from junction to case (RthJC) for VS-VS5HD480CW60 is 0.095 °C/W per module, as specified in the Thermal-Mechanical Specifications section. This value reflects the total thermal path across both diode legs and is measured from the average junction temperature to the mounting base surface.
Is VS-VS5HD480CW60 UL recognized?
Yes, VS-VS5HD480CW60 carries UL recognition under file number E222165, confirming compliance with UL 60747-1 for semiconductor devices. This certification applies to the module's construction, insulation integrity, and flammability rating - critical for inclusion in certified industrial power equipment.
What is the reverse recovery charge (Qrr) of VS-VS5HD480CW60 at 125 °C?
The reverse recovery charge (Qrr) of VS-VS5HD480CW60 is 2860 nC at TJ = 125 °C, as specified in the Dynamic Recovery Characteristics table. This elevated Qrr versus the 25 °C value (525 nC) reflects increased minority carrier lifetime at high temperature and must be accounted for in snubber and loss calculations for high-ambient applications.
