Product details
Overview
VS-VSKD196/08PBF from Vishay Semiconductors is a high-voltage, standard recovery power diode module in INT-A-PAK package, configured as a two-diode doubler circuit, rated for 195 A average forward current (IF(AV)), 800 V maximum repetitive peak reverse voltage (VRRM), and 3500 VRMS isolation. It delivers robust surge capability (4750 A IFSM at 50 Hz) and low thermal resistance (0.16 K/W junction-to-case) for industrial DC motor drives and welder power stages.
For engineers reviewing the VS-VSKD196/08PBF datasheet, VS-VSKD196/08PBF pinout, VS-VSKD196/08PBF application, or VS-VSKD196/08PBF equivalent, this page provides verified electrical ratings, thermal performance data, mounting torque specifications (4–6 Nm), isolation compliance (UL E78996), and real-world use context for high-current rectification in battery chargers and power converters.
Technical Context
The VS-VSKD196/08PBF integrates two high-voltage silicon diodes in a doubler configuration on a DBC (Al₂O₃) ceramic substrate, enabling bidirectional voltage doubling in single-phase rectifier topologies. Its electrically isolated base supports direct heatsink mounting without additional insulation.
It operates across –40 °C to +150 °C junction temperature range with glass-passivated chips, rated for 12 mA IRRM at 150 °C and 800 V VRRM, and exhibits low on-state slope resistance (rt1 = 1.3 mΩ, rt2 = 1.2 mΩ) ensuring predictable conduction loss under both linear and saturated current conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage doubler diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDA195-10N1 | 1000 V VRRM, 195 A IF(AV), TO-247-3L package, no integrated doubler configuration | Requires external wiring for doubler function; lacks DBC isolation and UL recognition | Select when higher reverse voltage margin is required and board-level isolation design is acceptable |
| Infineon DD100N12K | 1200 V VRRM, 100 A IF(AV), dual common-cathode configuration, not a doubler | Lower current rating; suited for parallel configurations but adds complexity and layout area | Choose only if system-level redesign allows paralleling and separate isolation implementation |
Compared with MDA195-10N1 and DD100N12K, VS-VSKD196/08PBF uniquely combines 800 V rating, 195 A capacity, pre-configured doubler topology, and certified 3500 VRMS isolation in a single INT-A-PAK module-reducing bill-of-materials, assembly steps, and validation effort for industrial rectifier designs.

FAQ
What is the maximum allowable case temperature for continuous operation of VS-VSKD196/08PBF?
The VS-VSKD196/08PBF is rated for continuous operation at a maximum case temperature (TC) of 100 °C, as defined by its 195 A IF(AV) specification under 180° conduction and half-sine wave conditions. Exceeding this temperature requires derating per the conduction-angle curves in Figure 10 of the datasheet to maintain reliability and avoid thermal runaway.
Does VS-VSKD196/08PBF require external heat sinking, and what is the recommended mounting torque?
Yes, VS-VSKD196/08PBF requires direct mounting to an externally cooled heatsink due to its 195 A current rating and power dissipation. The recommended mounting torque is 4–6 Nm for the three M6 screws securing the IAP base to the heatsink, with thermal compound applied and torque rechecked after 3 hours to accommodate compound spread.
What does the "D" in VS-VSKD196/08PBF signify in the ordering code?
The "D" in VS-VSKD196/08PBF denotes the circuit configuration: "D" stands for two-diode doubler circuit, as confirmed in the Vishay ordering information table and circuit configuration chart. This distinguishes it from "C" (common cathode), "J" (common anode), or "E" (single diode) variants within the same VS-VSK family.
Is VS-VSKD196/08PBF compliant with lead-free (RoHS) requirements?
Yes, VS-VSKD196/08PBF is PbF (lead-free) compliant, as indicated by the suffix "PbF" in its full part number and confirmed in Vishay Document Number 94357. It meets RoHS Directive 2011/65/EU and associated material restrictions, with full traceability documented in Vishay's material declarations.
What is the RMS insulation voltage rating and safety certification status of VS-VSKD196/08PBF?
VS-VSKD196/08PBF has a rated RMS insulation voltage (VINS) of 3500 VRMS between all terminals and the base, tested at 50 Hz for 1 second. It is UL recognized under file E78996, confirming compliance with UL 60747-1 for discrete semiconductor devices and supporting end-equipment safety certification.
