Product details
Overview
VS-VSKC196/04PBF from Vishay Semiconductors is a high-voltage, standard-recovery power diode module in INT-A-PAK package with common-cathode dual-diode configuration, 195 A average forward current (IF(AV)), 400 V maximum repetitive peak reverse voltage (VRRM), and 3500 VRMS electrical isolation. It is designed for industrial power conversion systems requiring robust surge handling and thermal stability.
For engineers reviewing the VS-VSKC196/04PBF datasheet, VS-VSKC196/04PBF pinout, VS-VSKC196/04PBF application, or VS-VSKC196/04PBF equivalent, this module delivers verified performance in high-current DC motor drives, battery chargers, and welder rectification where isolation, surge immunity, and low thermal resistance (RthJC = 0.16 K/W) are critical selection criteria.
Technical Context
This device integrates two standard-recovery silicon diodes on a direct-bonded copper (DBC) Al₂O₃ ceramic substrate, enabling electrically isolated operation with 3500 VRMS insulation between circuit and baseplate. Its common-cathode topology supports full-wave rectification without external interconnection of cathodes.
The module operates across –40 °C to +150 °C junction temperature range and sustains 4750 A non-repetitive surge current (IFSM, 50 Hz, t = 10 ms, no voltage reapplied), with forward voltage drop (VFM) of 1.38 V at π × IF(AV) and 25 °C. Thermal resistance from junction to case is specified at 0.16 K/W under DC conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 195 A - continuous average forward current per diode at 100 °C case temperature |
| VRRM | 400 V - maximum repetitive peak reverse voltage; defines safe blocking capability in rectifier bridges |
| IFSM (50 Hz) | 4750 A - single-cycle surge rating; supports welder arc initiation and motor startup transients |
| RthJC | 0.16 K/W - junction-to-case thermal resistance; enables efficient heatsink coupling for high-power dissipation |
| VFM | 1.38 V - forward voltage at π × IF(AV) and 25 °C; determines conduction loss in high-current applications |
| IRRM @ 150 °C | 20 mA - peak reverse leakage at max operating temperature; impacts efficiency in high-temperature environments |
| VINS | 3500 VRMS - RMS insulation voltage between terminals and baseplate; satisfies industrial safety isolation requirements |
Pinout & Package
VS-VSKC196/04PBF uses the INT-A-PAK power module package: 94.4 mm × 80 mm × 23 mm metal-base DBC ceramic housing with three M6 mounting screws, electrically isolating all terminals from the baseplate. The "C" in the part number denotes common-cathode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first diode | Accepts AC or unidirectional input; connects to transformer secondary or inverter leg |
| Anode 2 (A2) | Input terminal for second diode | Enables dual-input full-wave rectification; independent anode routing required |
| Cathode (K) | Common output node | Single DC output path for both diodes; reduces PCB trace count in bridge designs |
| Baseplate | Electrically isolated thermal interface | Mounts directly to heatsink; provides 3500 VRMS isolation; requires insulating thermal compound |
Key Features
| Feature | Design Value |
|---|---|
| DBC Al₂O₃ ceramic isolation | Enables safe integration into grounded-chassis systems without additional isolation barriers |
| UL approval (E78996) | Validates compliance with UL 60747-1 for industrial equipment safety certification |
| High surge I²t rating (113 kA²s) | Withstands repeated short-duration overloads typical in battery charging and welding duty cycles |

| Standard industrial footprint | Ensures mechanical compatibility with existing heatsink tooling and mounting hardware |
Applications
| DC Motor Drives | Battery Chargers |
|---|---|
Use Scenario: High-power industrial DC motor control using phase-controlled thyristor or diode rectifier front-end. IC Role / Device Role / Timing Role: Common-cathode dual-diode module serves as output rectifier in single-phase or three-phase uncontrolled bridge configurations. Use Value: Delivers 195 A average current per diode with 0.16 K/W thermal resistance, minimizing heatsink size while maintaining TJ ≤ 150 °C under continuous load. |
Use Scenario: Three-phase 400 VAC input battery charger for EV or energy storage systems. IC Role / Device Role / Timing Role: Dual-diode common-cathode module forms half of a six-pulse rectifier bridge, reducing component count vs. discrete diodes. Use Value: 3500 VRMS isolation eliminates need for separate isolation transformers; 4750 A surge rating handles inrush during capacitor pre-charge. |
| Welding Equipment | Industrial Power Converters |
Use Scenario: Inverter-based arc welder with high-duty-cycle pulsed output. IC Role / Device Role / Timing Role: Rectifies transformer secondary output prior to DC link filtering; operates in intermittent high-current bursts. Use Value: 113 kA²s I²t rating ensures fusing margin beyond worst-case short-circuit events; glass passivation prevents surface degradation under plasma exposure. |
Use Scenario: Medium-voltage AC/DC converter for factory automation or renewable energy inverters. IC Role / Device Role / Timing Role: High-current, high-isolation rectification stage in multi-kW power supplies feeding downstream IGBT or SiC modules. Use Value: INT-A-PAK package allows direct bolt-down to liquid-cooled cold plates; 400 V VRRM supports 230/400 VAC line inputs with safety margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VS-VSKJ196/04PBF | Common-anode configuration instead of common-cathode; identical IF(AV), VRRM, and RthJC | Requires reversed PCB layout for output polarity; suited for positive-ground systems or complementary bridge topologies | Select when system architecture demands shared anode connection rather than shared cathode |
| VS-VSKD196/04PBF | Doubler-circuit configuration (two series diodes); same voltage/current ratings but doubled VRRM per string | Supports higher DC bus voltages without series stacking; occupies same footprint but different internal routing | Choose for 800 V DC link designs where single-module voltage doubling simplifies layout vs. discrete series pairs |
Compared with VS-VSKC196/04PBF, VS-VSKJ196/04PBF offers identical power handling but inverted polarity output, while VS-VSKD196/04PBF provides double the blocking voltage per string-enabling higher DC bus operation without increasing module count or board area.

FAQ
What is the maximum junction temperature rating for VS-VSKC196/04PBF?
The VS-VSKC196/04PBF has a maximum junction operating and storage temperature range of –40 °C to +150 °C. This rating is validated per Vishay's qualification standards and enables reliable operation in demanding industrial environments such as welders and motor drives where ambient temperatures exceed 85 °C.
Does VS-VSKC196/04PBF require external heat sinking?
Yes, VS-VSKC196/04PBF requires a properly mounted heatsink. With a junction-to-case thermal resistance of 0.16 K/W and typical power dissipation exceeding 200 W at full load, thermal management is essential. Mounting torque must be 4–6 Nm with thermal compound to maintain specified RthCS of 0.05 K/W.
Is VS-VSKC196/04PBF lead-free and RoHS compliant?
Yes, the "PbF" suffix in VS-VSKC196/04PBF explicitly indicates lead-free and RoHS-compliant construction per Vishay's material categorization standard (document 99912). The module meets JEDEC J-STD-609 Category 1 marking requirements for lead-free terminations.
What does the "C" in VS-VSKC196/04PBF signify?
The "C" denotes common-cathode circuit configuration: two diodes share a single cathode terminal while maintaining independent anodes. This allows full-wave rectification with simplified DC-side wiring and is distinct from "J" (common-anode), "D" (doubler), or "E" (single-diode) variants in the VS-VSK family.
Can VS-VSKC196/04PBF be used in three-phase rectifier applications?
Yes, VS-VSKC196/04PBF is commonly deployed in three-phase rectifiers-typically three modules (one per phase) configured as a six-pulse bridge. Its 195 A IF(AV) rating, 4750 A IFSM, and 0.16 K/W RthJC support continuous operation in such topologies at rated load with appropriate heatsinking and airflow.
