Product details
Overview
VS-VSKD236/04PBF from Vishay Semiconductors is a high-voltage, standard recovery power diode module in INT-A-PAK package, configured as a two-diode doubler circuit. It delivers 230 A average forward current (IF(AV)), 400 V maximum repetitive peak reverse voltage (VRRM), and features electrically isolated DBC ceramic substrate with 3500 VRMS insulation. It is designed for industrial DC motor drives and battery chargers requiring robust surge handling and thermal stability.
For engineers reviewing the VS-VSKD236/04PBF datasheet, VS-VSKD236/04PBF pinout, VS-VSKD236/04PBF application, or VS-VSKD236/04PBF equivalent, key selection criteria include its 230 A IF(AV) rating, 400 V VRRM, 5500 A IFSM (10 ms, 50 Hz), 0.14 K/W RthJC, and UL E78996 approval - all critical for high-current rectification in rugged industrial power systems.
Technical Context
The VS-VSKD236/04PBF implements a two-diode doubler configuration within a single INT-A-PAK power module, enabling compact full-wave rectification without external interconnects. Its DBC (Al₂O₃) ceramic base provides electrical isolation between terminals and heatsink, supporting safe operation at 3500 VRMS.
It uses glass-passivated silicon chips rated for TJ = –40 °C to +150 °C, with low on-state resistance (rt1 = 1.2 mΩ, rt2 = 1.07 mΩ) and forward voltage drop (VFM = 1.46 V at π × IF(AV), 25 °C), optimized for low conduction loss in continuous high-current applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 230 A - maximum average forward current at 100 °C case temperature, defining continuous DC output capability |
| VRRM | 400 V - maximum repetitive peak reverse voltage, sets safe blocking margin for 280 VAC input rectification |
| IFSM (50 Hz) | 5500 A - non-repetitive surge current tolerance for 10 ms, enabling reliable startup and fault withstand |
| RthJC | 0.14 K/W - junction-to-case thermal resistance per diode, enabling efficient heat transfer to heatsink |
| I²t (50 Hz) | 151 kA²s - fusing energy rating, used for coordination with upstream fast-acting fuses |
| VFM | 1.46 V - forward voltage drop at π × IF(AV) and 25 °C, directly determining conduction loss at rated current |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VS-VSKJ236/04PBF | Same IF(AV) = 230 A, VRRM = 400 V, but common-anode configuration instead of doubler | Requires external wiring for doubler function; not drop-in for VS-VSKD236/04PBF's internal topology | Select only if redesigning for separate anode routing and independent diode control |
| IXYS MDA230-16N1B | Higher VRRM = 1600 V, same IF(AV) = 230 A, but TO-247-3L package with no internal isolation | Lacks 3500 VRMS isolation; requires external insulating hardware and heatsink design changes | Choose when higher blocking voltage is needed and isolation can be implemented externally |

FAQ
What is the maximum operating junction temperature for VS-VSKD236/04PBF?
The VS-VSKD236/04PBF has a specified maximum junction operating temperature of +150 °C, with storage temperature range from –40 °C to +150 °C. This rating is validated under DC operation with proper heatsinking and accounts for thermal resistance RthJC = 0.14 K/W per diode. Operation beyond this limit risks irreversible degradation of the glass-passivated silicon die.
Does VS-VSKD236/04PBF require external heatsinking, and what is the recommended mounting torque?
Yes, VS-VSKD236/04PBF requires external heatsinking due to its 230 A IF(AV) rating and associated conduction losses. Mounting torque to the heatsink must be 4–6 Nm on the three M6 screws, using lubricated threads and a mounting compound. Torque should be rechecked after 3 hours to accommodate compound spread and ensure consistent thermal interface resistance (RthCS = 0.05 K/W).
Is VS-VSKD236/04PBF RoHS-compliant and lead-free?
Yes, VS-VSKD236/04PBF is RoHS-compliant and lead-free, as indicated by the "PbF" suffix in its part number. It meets EU Directive 2011/65/EU and Vishay's material categorization per document 99912, with full traceability and declaration available upon request.
How is the doubler configuration implemented internally in VS-VSKD236/04PBF?
The VS-VSKD236/04PBF integrates two high-voltage diodes in a fixed doubler topology: Terminal 1 is Anode A, Terminal 2 is Cathode A (and Anode B), and Terminal 3 is Cathode B. This internal connection eliminates external wiring, reduces stray inductance, and enables compact full-wave voltage doubling - confirmed in Vishay document 94357, Figure "CIRCUIT CONFIGURATION D".
What is the insulation voltage rating and safety certification status of VS-VSKD236/04PBF?
VS-VSKD236/04PBF provides 3500 VRMS isolation between all terminals and the base plate (tested at 50 Hz, 1 s), and is UL recognized under file E78996. This certification validates its suitability for industrial equipment requiring reinforced insulation per IEC 61800-5-1 and UL 508, with no additional creepage/clearance design required beyond standard INT-A-PAK mounting guidelines.
