Product details
Overview
VS-VSKD196/04PBF from Vishay Semiconductors is a high-voltage, standard recovery power diode module in INT-A-PAK package, configured as a two-diode doubler circuit, 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 (Al₂O₃) substrate and is designed for industrial power conversion systems requiring robust surge handling and thermal stability.
For engineers reviewing the VS-VSKD196/04PBF datasheet, VS-VSKD196/04PBF pinout, VS-VSKD196/04PBF application, or VS-VSKD196/04PBF equivalent, this module is evaluated for high-current DC motor drives, battery chargers, welders, and single-phase bridge configurations where electrical isolation, I²t fusing capability (113 kA²s), and low thermal resistance (RthJC = 0.16 K/W per junction) are critical selection criteria.
Technical Context
The VS-VSKD196/04PBF implements a two-diode doubler configuration - two series-connected diodes sharing a common terminal - enabling voltage-doubling rectification in compact industrial power supplies. Its DBC Al₂O₃ substrate provides 3500 VRMS galvanic isolation between terminals and heatsink, satisfying UL E78996 safety certification.
Thermally, it delivers RthJC = 0.16 K/W per junction under DC operation and supports 4750 A non-repetitive surge current (IFSM, 10 ms, 50 Hz) at TJ = 150 °C. Forward conduction is characterized by dual-slope on-state behavior: VF(TO)₁ = 0.69 V and rt₁ = 1.3 mΩ at low current, transitioning to VF(TO)₂ = 0.78 V and rt₂ = 1.2 mΩ at high current.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VS-VSKJ196/04PBF | Two-diode common-anode configuration (vs. doubler); identical IF(AV), VRRM, and RthJC | Suitable for dual-output or split-rail supplies, not voltage doubling | Select when independent anode switching or dual-channel rectification is required instead of series voltage multiplication |
