introduced three new series of three-phase-bridge power modules designed to increase efficiency and reliability for heavy-duty industrial-level applications. The Vishay Semiconductors VS-130MT…C, VS-160MT…C, and VS-300MT…C series deliver higher output current, blocking voltage, and surge current than previous-generation solutions while offering improved thermal resistance in the 5-terminal MTC package.
The devices released today feature high output current from 130 A to 300 A and blocking voltage to 1800 V. For high efficiency, the power modules offer surge current to 2,512 A and an electrically insulated case for excellent junction-to-case thermal resistance down to 0.23 °C/W. The devices’ robust MTC plastic package provides high reliability, while its screw terminals allow for compatibility with competing solutions.
The VS-130MT…C, VS-160MT…C, and VS-300MT…C series provide three-phase rectification for industrial power supplies, high-frequency welding, plasma cutting, and industrial battery chargers, in addition to input rectification for AC/DC motor controls. The RoHS-compliant devices offer 3600 VRMS insulation voltage and are pending UL approval.
Device Specification Table:
| Part number | VS-130MT…C | VS-160MT…C | VS-300MT…C |
| Output current (A) | 130 @ 120 °C | 160 @ 118 °C | 300 @ 100 °C |
| Reverse voltage (V) | 1600 to 1800 | 1600 to 1800 | 1600 to 1800 |
| Surge current @ 60 Hz (A) | 1330 | 1610 | 2512 |
| Thermal resistance, junction-to-case (°C/W) | 0.41 | 0.35 | 0.23 |
Samples and production quantities of the new power modules are available now, with lead times of eight to 10 weeks for large orders. Pricing for U.S. delivery only begins at $30 per piece for the VS-130MT…C series, $32 for the VS-160MT…C series, and $38 for the VS-300MT…C series.
