Product details
Overview
VS-VSKC196/08PBF from Vishay Semiconductors is a high-voltage, standard recovery power diode module in INT-A-PAK package with common-cathode dual-diode configuration, rated for 195 A average forward current (IF(AV)), 800 V maximum repetitive peak reverse voltage (VRRM), and 3500 VRMS isolation. It employs glass-passivated chips on DBC ceramic substrate and is designed for industrial power conversion systems requiring robust surge handling and thermal stability.
For engineers reviewing the VS-VSKC196/08PBF datasheet, VS-VSKC196/08PBF pinout, VS-VSKC196/08PBF application, or VS-VSKC196/08PBF equivalent, this module delivers verified 195 A IF(AV) at 100 °C case temperature, 0.16 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 isolation, surge immunity, and long-term thermal reliability are mandatory.
Technical Context
The VS-VSKC196/08PBF integrates two electrically isolated, glass-passivated silicon diodes in a common-cathode configuration within a single INT-A-PAK module. Its DBC (Al₂O₃) ceramic base provides 3500 VRMS galvanic isolation between circuit terminals and heatsink mounting surface, enabling safe operation in grounded-heatsink topologies.
It supports 4750 A non-repetitive surge current (IFSM) at 60 Hz for t = 8.3 ms with no voltage reapplied, and exhibits low on-state conduction losses: VF(TO)₁ = 0.69 V and rt₁ = 1.3 mΩ at TJ = 150 °C - optimized for high-efficiency, high-duty-cycle rectification in industrial converters.

FAQ
What is the maximum allowable case temperature for continuous operation of VS-VSKC196/08PBF?
The VS-VSKC196/08PBF is rated for continuous operation up to 100 °C case temperature (TC) at its full 195 A average forward current (IF(AV)). Exceeding this temperature requires linear derating per the datasheet's conduction-angle curves, and junction temperature must remain ≤150 °C under all conditions. Thermal design must account for RthJC = 0.16 K/W and interface resistance to heatsink.
Does VS-VSKC196/08PBF support common-cathode configuration in three-phase rectifier topologies?
Yes, VS-VSKC196/08PBF is explicitly configured as a two-diode common-cathode module (circuit code "C"), making it suitable for use in three-phase half-wave rectifiers or as one phase leg in modular six-pulse bridges. Its dual-anode/single-cathode pinout allows direct integration without external interconnects between anodes.
What is the isolation voltage rating and how is it implemented in VS-VSKC196/08PBF?
The VS-VSKC196/08PBF provides 3500 VRMS galvanic isolation between all power terminals and the metal base/heatsink interface, achieved via aluminum oxide (Al₂O₃) Direct Bonded Copper (DBC) ceramic substrate. This eliminates the need for insulating washers or pads when mounting to grounded heatsinks in industrial equipment.
Can VS-VSKC196/08PBF be paralleled with identical units for higher current capacity?
Yes, VS-VSKC196/08PBF supports parallel operation due to its matched forward voltage characteristics (VF(TO)₁ = 0.69 V, rt₁ = 1.3 mΩ) and symmetric thermal path. Successful paralleling requires balanced busbar inductance, matched mounting torque (4–6 Nm), and uniform thermal interface to avoid current imbalance and localized overheating.
Is VS-VSKC196/08PBF certified for safety standards applicable in North America?
Yes, VS-VSKC196/08PBF carries UL recognition under file E78996, confirming compliance with UL 60747-1 for semiconductor devices. This certification validates its construction, isolation, flammability, and dielectric strength for use in end equipment seeking UL listing in North American markets.
