Product details
Overview
VS-301MT160C from Vishay Semiconductors is a three-phase bridge rectifier module rated for 300 A average output current at 100 °C case temperature, with maximum repetitive peak reverse voltage (VRRM) of 1600 V and 3600 VRMS isolation voltage. It features electrically insulated MTC package, high surge capability (2512 A @ 60 Hz), and low junction-to-case thermal resistance (0.23 °C/W per junction), designed for industrial motor drives and heavy-duty AC/DC conversion.
For engineers reviewing the VS-301MT160C datasheet, VS-301MT160C pinout, VS-301MT160C application, or VS-301MT160C equivalent, key selection criteria include its 1600 V blocking rating, 300 A DC conduction capability at 120° rectification, dual-level forward voltage characteristics (0.79 V / 0.96 V threshold), and UL E78996 certification for safety-critical power systems.
Technical Context
The VS-301MT160C integrates six silicon diodes in a single-phase-in, three-phase-out bridge configuration with common cathode/anode layout. Its thermal design relies on direct copper baseplate mounting and electrically isolated case, enabling operation up to 150 °C junction temperature while maintaining RthJC = 0.23 °C/W per junction under DC conditions.
Electrical behavior is defined by two forward conduction regimes: low-current threshold (VFT(TO)1 = 0.79 V) and high-current slope (rf2 = 3.22 mΩ), resulting in VFM = 1.7 V at 300 A peak per junction. Surge withstand is specified for both 50 Hz (2400 A) and 60 Hz (2512 A) half-sine pulses with no voltage reapplied.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1600 V - Maximum repetitive reverse voltage; defines safe AC line input range up to 1130 V RMS. |
| IO | 300 A at TC = 100 °C - Continuous DC output current limit under 120° conduction angle. |
| IFSM | 2512 A @ 60 Hz - Non-repetitive surge current handling for short-circuit protection in drive inverters. |
| VFM | 1.7 V @ 300 A, 25 °C - Forward voltage drop per junction; determines conduction loss and thermal load. |
| RthJC | 0.23 °C/W per junction - Junction-to-case thermal resistance; enables precise heatsink sizing for 150 °C max TJ. |
| VISOL | 3600 VRMS - Isolation voltage between terminals and case; satisfies reinforced insulation requirements. |
| Weight | 235 g - Module mass impacts mechanical mounting and thermal interface design in cabinet layouts. |
Pinout & Package
VS-301MT160C uses the MTC (Modular Three-phase Compact) package: 80 mm × 72 mm × 24.5 mm metal baseplate with five M6 mounting screws, electrically insulated case, and terminal layout optimized for three-phase AC input (L1/L2/L3), DC+ and DC− outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L1, L2, L3 | AC Input Phases | Three-phase AC line connections; symmetrical layout minimizes stray inductance in high-di/dt switching. |
| DC+ | Bridge Anode Common | Positive DC output node; connects to capacitor bank or inverter DC link; rated for full 300 A continuous. |
| DC− | Bridge Cathode Common | Negative DC output node; serves as return path for all three phases; shares same current rating as DC+. |
| Case | Electrically Isolated Heat Sink Interface | Thermally conductive but electrically isolated mounting surface; requires thermal compound and 5 Nm torque. |
Key Features
| Feature | Design Value |
|---|---|
| UL E78996 Certification | Validated reinforced insulation system enabling use in safety-critical industrial equipment without additional barrier design. |
| High Surge Capability | 2512 A non-repetitive surge current supports IGBT short-circuit protection timing in VFDs without derating. |
| Low Thermal Resistance | 0.23 °C/W per junction allows 150 °C junction operation with standard heatsinks, reducing cooling overhead. |
| Dual-Range Forward Characteristics | Separate VFT(TO) and rf values enable accurate loss modeling across light-load to full-load operating ranges. |
| Compact Power Volume Ratio | 235 g mass delivering 300 A/1600 V in 142,560 mm³ volume improves power density over discrete diode solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDA300-1600 | Same 1600 V VRRM, but higher IO = 350 A; RthJC = 0.19 °C/W; larger TO-247-based module footprint. | Preferred where higher continuous current headroom is needed and PCB space permits larger outline. | Select when thermal budget is tighter and heatsink interface area exceeds VS-301MT160C's MTC baseplate. |
| Infineon DDB6U16N16 | Lower VRRM = 1600 V but only 200 A IO; uses press-fit SOT-227B package; no UL certification. | Suitable for cost-sensitive, lower-power industrial controls where isolation certification is not mandated. | Choose only if system-level safety testing can compensate for missing UL E78996 approval. |
Compared with MDA300-1600 and DDB6U16N16, the VS-301MT160C delivers optimal balance of certified isolation, compact MTC packaging, and verified 300 A/1600 V performance-making it the preferred choice for UL-compliant, space-constrained industrial rectifier designs.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-301MT160C?
The VS-301MT160C supports continuous operation up to 110 °C case temperature (TC) as specified in its major ratings table. At this temperature, the device delivers 258 A average output current. For the full 300 A rating, case temperature must be limited to 100 °C under 120° rectification conditions. Exceeding 110 °C risks exceeding the 150 °C maximum junction temperature.
Does the VS-301MT160C require forced air cooling in typical industrial applications?
The VS-301MT160C does not mandate forced air cooling if properly mounted to a heatsink with RthCS ≤ 0.03 °C/W and ambient temperature ≤ 50 °C. With a 0.1 °C/W system thermal resistance (RthSA), the module sustains 300 A output at 100 °C case temperature. Forced air may be needed only in enclosed cabinets with poor natural convection or ambient > 60 °C.
Is the VS-301MT160C pin-compatible with other Vishay MTC-series modules like VS-301MT180C?
No, the VS-301MT160C is not pin-compatible with VS-301MT180C. Although both share the MTC package outline and terminal positions, the 160C and 180C variants differ in internal die configuration and voltage grading-requiring distinct PCB layouts and gate drive isolation schemes. Always verify mechanical drawings (Doc. 96003) before substitution.
What is the meaning of the "C" suffix in VS-301MT160C?
The "C" suffix in VS-301MT160C denotes the standard version with electrically insulated case and UL E78996 certification. Vishay uses "C" to distinguish this safety-certified variant from non-insulated or non-UL versions (e.g., "N" or blank suffixes) that lack reinforced isolation and cannot be used in applications requiring regulatory compliance.
Can the VS-301MT160C be used in 600 VAC three-phase systems?
No-the VS-301MT160C is rated for maximum 1600 V repetitive reverse voltage (VRRM), which corresponds to safe operation with ≤ 1130 V RMS line-to-line input. A 600 VAC system yields ~1040 V peak line-to-line, leaving only ~560 V margin below VRRM. While technically possible, this violates Vishay's recommended 2× safety factor for industrial transients; 1800 V-rated variants (e.g., VS-301MT180C) are advised for 600 VAC systems.
