Product details
Overview
VS-160MT120KPBF from Vishay Semiconductors is a three-phase bridge rectifier power module rated for 160 A average output current at 85 °C case temperature, 1200 V maximum repetitive peak reverse voltage (VRRM), and featuring 4000 VRMS isolation voltage in an MTK package. It delivers low forward voltage drop (1.49 V at 200 A, 25 °C) and high surge capability (1500 A IFSM at 60 Hz), designed for industrial motor drives and heavy-duty AC/DC conversion.
For engineers reviewing the VS-160MT120KPBF datasheet, VS-160MT120KPBF pinout, VS-160MT120KPBF application, or VS-160MT120KPBF equivalent, key selection criteria include thermal resistance (RthJC = 0.12 K/W per module), forward slope resistance (3.13 mΩ at high current), and UL E78996 approval for safety-critical installations.
Technical Context
This module integrates six silicon diodes in a three-phase full-wave bridge configuration with electrically insulated case and industry-standard INT-A-PAK compatible MTK footprint. Its thermal design supports DC and 120° rectified conduction modes, with junction-to-case thermal resistance optimized for forced-air or liquid-cooled heatsink mounting.
Rated for -40 °C to +150 °C operating and storage temperature range, it sustains 102,000 A²√s I²√t fusing energy under 10 ms non-repetitive surge conditions and maintains stable forward conduction characteristics across its full current range via dual-threshold voltage behavior (VT(TO)₁ = 0.81 V, VT(TO)₂ = 1.04 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive reverse blocking voltage per diode leg; defines usable AC input voltage range up to ~850 V RMS line-to-line. |
| IO (TC = 85 °C) | 160 A - Continuous DC output current rating at 85 °C case temperature; derates linearly above this point. |
| IFSM (60 Hz) | 1500 A - Peak non-repetitive surge current handling; supports motor startup and short-circuit fault tolerance. |
| RthJC (per module) | 0.12 K/W - Junction-to-case thermal resistance; enables efficient heat transfer to heatsink with minimal ΔT rise per watt dissipated. |
| VFM (200 A, 25 °C) | 1.49 V - Forward voltage drop at high pulse current; directly determines conduction loss and thermal load at rated output. |
| rf2 | 3.13 mΩ - High-current forward slope resistance; used to calculate dynamic conduction losses beyond threshold voltage. |
| Visol | 4000 VRMS - Isolation voltage between terminals and case; satisfies reinforced insulation requirements for industrial safety standards. |

FAQ
What is the maximum case temperature for continuous operation of the VS-160MT120KPBF?
The VS-160MT120KPBF is rated for continuous operation at a maximum case temperature (TC) of 85 °C when delivering its full 160 A average output current. At higher case temperatures, output current must be linearly derated per the datasheet's current rating curves-e.g., to ~120 A at TC = 100 °C. This limit ensures junction temperature remains within the -40 °C to +150 °C operational range under specified thermal conditions.
Does the VS-160MT120KPBF require external snubbers or RC networks for typical three-phase rectifier operation?
The VS-160MT120KPBF does not require external snubbers for standard 50/60 Hz three-phase rectification with inductive loads, as its 1200 V VRRM and soft recovery characteristics provide adequate voltage margin and dv/dt immunity. However, snubbers may be added in high-dv/dt environments (e.g., adjacent to fast-switching IGBTs) to suppress commutation spikes-design validation using oscilloscope measurements at the AC terminals is recommended.
How is thermal interface managed between the VS-160MT120KPBF baseplate and heatsink?
The VS-160MT120KPBF baseplate is electrically insulated but thermally conductive. A thermal interface material (TIM) such as silicone grease or phase-change pad is required between the module and heatsink. Mounting torque must be 4–6 Nm with lubricated M5 screws; Vishay recommends re-torquing after 3 hours to accommodate TIM spread. RthCS is specified at 0.03 K/W under these conditions.
Is the VS-160MT120KPBF compliant with RoHS and REACH regulations?
Yes, the VS-160MT120KPBF is lead (Pb)-free and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "PbF" suffix explicitly denotes Vishay's lead-free construction, and material declarations per Vishay Doc. #99912 confirm full substance compliance across all homogeneous materials in the device.
Can the VS-160MT120KPBF be paralleled with another unit for higher current capacity?
Paralleling VS-160MT120KPBF units is not recommended due to mismatch in forward voltage characteristics (VT(TO)₂ = 1.04 V ± tolerance) and thermal coupling limitations. For >160 A applications, Vishay specifies higher-rated modules (e.g., VS-200MT120KPBF) or multi-module systems with active current balancing. If parallel operation is unavoidable, individual current-sharing resistors and matched heatsinking are mandatory.
