Product details
Overview
VS-110MT160KPBF from Vishay Semiconductors is a three-phase bridge rectifier module rated for 110 A average output current and 1600 V maximum repetitive peak reverse voltage (VRRM). It features electrically insulated case, 4000 VRMS isolation, UL E78996 approval, and MTK package compatible with industry-standard INT-A-PAK power modules. It delivers reliable rectification in industrial motor drives and heavy-duty AC/DC conversion systems.
For engineers reviewing the VS-110MT160KPBF datasheet, VS-110MT160KPBF pinout, VS-110MT160KPBF application, or VS-110MT160KPBF equivalent, this page provides verified thermal resistance (RthJC = 0.18 °C/W per module), forward voltage drop (VFM = 1.4 V at 150 A, 25 °C), surge capability (IFSM = 1000 A at 60 Hz), junction temperature range (–40 to +150 °C), and mounting torque specification (4–6 Nm to heatsink).
Technical Context
This device integrates six high-efficiency silicon diodes in a single-phase-input, three-phase-output bridge configuration with common-cathode and common-anode terminals. Its thermally optimized MTK package enables direct heatsink mounting via M5 screws and achieves low junction-to-case thermal resistance of 0.18 °C/W under DC operation per module.
The VS-110MT160KPBF operates across –40 °C to +150 °C junction temperature range and supports 120° rectification conduction angle. Its I2t rating of 4100 A2s (8.3 ms, no voltage reapplied) and I2√t rating of 45,000 A2√s ensure robust short-circuit withstand capability in industrial inverters and UPS systems.
Key Specifications

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 MDA110-16N1 | 110 A / 1600 V, TO-247-3L discrete diode module; higher RthJC (0.35 °C/W), no integrated isolation | Requires external insulator and heatsink interface; suitable where modularity or board-level integration is preferred over bolt-down packaging | Select when PCB mounting or custom thermal interface is required; verify creepage/clearance compliance separately |
| Vishay VS-110MT120KPBF | Same MTK package, but 1200 V VRRM; identical IO, RthJC, and pinout; lower cost for 400–480 VAC systems | Optimized for 400–480 VAC input; insufficient blocking margin for 690 VAC or high-transient industrial grids | Choose for cost-sensitive 480 VAC applications where 1200 V rating suffices; not interchangeable in 690 VAC designs |
Compared with VS-110MT120KPBF, the VS-110MT160KPBF adds 400 V blocking headroom for 690 VAC systems and transient immunity, while MDA110-16N1 trades integrated isolation and mechanical robustness for layout flexibility - making VS-110MT160KPBF optimal for bolt-down, safety-critical industrial rectification.

FAQ
What is the maximum continuous output current rating for VS-110MT160KPBF?
The VS-110MT160KPBF is rated for 110 A average DC output current under 120° rectification conduction angle at case temperature of 90 °C. This rating assumes proper heatsinking with mounting torque of 4–6 Nm and thermal interface compound applied per Vishay specification document 94352.
Does VS-110MT160KPBF require an external insulator when mounted to a metal heatsink?
No - the VS-110MT160KPBF features an electrically insulated case with 4000 VRMS isolation, enabling direct mounting to grounded heatsinks without additional insulating hardware. This eliminates the need for mica washers or ceramic spacers in most industrial installations.
What is the forward voltage drop specification for VS-110MT160KPBF at rated current?
The VS-110MT160KPBF has a maximum forward voltage drop (VFM) of 1.4 V at Ipk = 150 A and TJ = 25 °C, measured with 400 μs pulse width on a single junction. At elevated junction temperatures, VFM decreases slightly due to negative temperature coefficient of silicon diodes.
Is VS-110MT160KPBF RoHS-compliant and lead-free?
Yes - the "KPBF" suffix in VS-110MT160KPBF explicitly denotes lead (Pb)-free construction compliant with RoHS Directive 2011/65/EU. Vishay confirms full compliance per its material categorization standard documented in www.vishay.com/doc?99912.
What is the thermal resistance from junction to case (RthJC) for VS-110MT160KPBF?
The VS-110MT160KPBF has a maximum junction-to-case thermal resistance of 0.18 °C/W under DC operation per module, as specified in Vishay document 94352. This value applies when mounted with recommended thermal compound and 4–6 Nm screw torque to a flat, greased heatsink surface.
