Product details
Overview
VS-VSKJ236/04PBF from Vishay Semiconductors is a high-voltage, standard recovery power diode module in INT-A-PAK package with common-anode dual-diode configuration, rated for 230 A average forward current (IF(AV)), 400 V repetitive peak reverse voltage (VRRM), and 3500 VRMS electrical isolation. It employs glass-passivated chips mounted on DBC ceramic (Al₂O₃) substrate and is designed for industrial power conversion systems requiring robust surge handling and thermal stability.
For engineers reviewing the VS-VSKJ236/04PBF datasheet, VS-VSKJ236/04PBF pinout, VS-VSKJ236/04PBF application, or VS-VSKJ236/04PBF equivalent, this module delivers verified 5500 A non-repetitive surge capability at 50 Hz, 0.14 K/W junction-to-case thermal resistance, and UL E78996 approval - critical for high-current DC motor drives, battery chargers, and welder rectifier stages where reliability under transient overload and thermal cycling is mandatory.
Technical Context
The VS-VSKJ236/04PBF implements a two-diode common-anode configuration within a single INT-A-PAK power module, enabling half-wave or full-wave rectification topologies without discrete interconnects. Its DBC Al₂O₃ substrate provides electrically isolated mounting and supports 3500 VRMS insulation between circuit and heatsink.
It operates across –40 °C to +150 °C junction temperature range, with forward conduction characterized by low on-state slope resistances (rt1 = 1.2 mΩ, rt2 = 1.07 mΩ) and threshold voltages (VF(TO)1 = 0.70 V, VF(TO)2 = 0.83 V) measured at TJ = 150 °C - ensuring predictable power loss behavior in high-duty-cycle industrial converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 230 A - maximum continuous average forward current at 100 °C case temperature, defining steady-state conduction capacity |
| VRRM | 400 V - maximum repetitive peak reverse voltage, sets safe blocking margin for 280 VAC input rectification |
| IFSM (50 Hz) | 5500 A - one-cycle non-repetitive surge rating, supports short-circuit withstand in motor drive inverters |
| RthJC | 0.14 K/W - junction-to-case thermal resistance per junction, enables high-power dissipation with minimal ΔT |
| I²t (50 Hz) | 151 kA²s - fusing I²t value, determines fuse coordination time-current curve selection |
| VINS | 3500 VRMS - RMS insulation voltage between terminals and baseplate, satisfies reinforced isolation requirements |
| IRRM @ 150 °C | 20 mA - peak reverse leakage at max junction temperature, impacts standby loss in high-impedance circuits |
Pinout & Package
VS-VSKJ236/04PBF uses the INT-A-PAK industrial power module package (94.4 mm × 35 mm × 23 mm), featuring three M6 mounting screws, copper baseplate for direct heatsink attachment, and electrically isolated DBC Al₂O₃ substrate.

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 | Lower IF(AV) = 195 A, higher RthJC = 0.16 K/W, same VRRM = 400 V and package | Suitable for 30–40 kW systems with lower thermal margin; reduced surge rating (4750 A vs. 5500 A) | Select when system peak current remains below 4200 A and thermal design allows +14 °C higher junction rise |
| IXYS MDA500-16N1 | 1600 V VRRM, IF(AV) = 500 A, TO-247-3L package, no integrated isolation | Targets high-voltage DC link applications (>1000 V); requires external isolation and heatsink design | Choose only when >1000 V blocking is required and board-level isolation can be implemented |

FAQ
What is the mounting torque specification for VS-VSKJ236/04PBF?
The recommended mounting torque for VS-VSKJ236/04PBF is 4 to 6 Nm for IAP-to-heatsink fasteners, using lubricated threads and a mounting compound. Vishay specifies rechecking torque after 3 hours to accommodate compound spread, ensuring consistent thermal contact and mechanical reliability over thermal cycling in industrial deployments of VS-VSKJ236/04PBF.
Does VS-VSKJ236/04PBF support three-phase bridge configurations?
Yes, VS-VSKJ236/04PBF supports three-phase bridge use via parallel connection of multiple modules - for example, three VS-VSKJ236/04PBF units (each with common-anode configuration) can form a six-pulse rectifier. Figure 27 in the datasheet confirms total power loss curves for "3 x VSK.236.. Series Three phase bridge Connected", validating its suitability in such topologies.
What is the forward voltage drop of VS-VSKJ236/04PBF at rated current?
At IFM = π × IF(AV) = ~722 A and TJ = 25 °C, the maximum forward voltage drop (VFM) of VS-VSKJ236/04PBF is 1.46 V. This value reflects worst-case conduction loss under cold-start conditions and is used with on-state slope resistances (rt1 = 1.2 mΩ, rt2 = 1.07 mΩ) to calculate dynamic power dissipation in VS-VSKJ236/04PBF-based designs.
Is VS-VSKJ236/04PBF RoHS-compliant and lead-free?
Yes, the "PbF" suffix in VS-VSKJ236/04PBF explicitly denotes lead-free (RoHS-compliant) construction per Vishay's material categorization standard (document 99912). The device meets EU RoHS Directive 2011/65/EU and is compatible with standard SnAgCu reflow profiles for lead-free assembly processes involving VS-VSKJ236/04PBF.
How does the common-anode configuration of VS-VSKJ236/04PBF affect circuit layout?
The common-anode configuration of VS-VSKJ236/04PBF places both anodes (A1, A2) as separate high-side inputs and the cathode (K) as the unified low-side output. This simplifies PCB routing for dual-input rectifiers - e.g., splitting transformer secondaries - while requiring careful ground-plane design to avoid circulating currents in the shared cathode path of VS-VSKJ236/04PBF.
