Product details
Overview
VS-26MT60 from Vishay Semiconductors is a compact, encapsulated three-phase bridge rectifier rated for 25 A DC output current at 70 °C case temperature, with 600 V maximum repetitive peak reverse voltage (VRRM), low forward voltage drop (1.26 V at 40 A peak per junction), and electrically insulated D-63 package. It serves as the primary AC-to-DC conversion stage in industrial motor drives and HVAC control systems.
For engineers reviewing the VS-26MT60 datasheet, VS-26MT60 pinout, VS-26MT60 application, or VS-26MT60 equivalent, key selection criteria include its 1.42 K/W junction-to-case thermal resistance, UL E300359 approval, 2700 V RMS isolation voltage, and compatibility with Pb-free soldering at 260–275 °C using SAC305 alloy.
Technical Context
The VS-26MT60 implements a monolithic three-phase full-wave bridge configuration with six silicon diode junctions arranged in a standard 3-phase input (AC1–AC3) to dual-polarity DC output (+/−) topology. Its D-63 package integrates electrically insulated metal baseplate, center-hole mechanical mounting, and universal terminals supporting push-on, wrap-around, or solder termination.
Thermal performance is defined by a steady-state RthJC of 1.42 K/W per bridge under DC operation, enabling reliable conduction at 25 A with case temperature limited to 70 °C. The device sustains non-repetitive surge currents up to 360 A (10 ms, 50 Hz, no voltage reapplied) and exhibits I²t fusing values of 635 A²s under identical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (DC Output Current) | 25 A at TC = 70 °C - defines continuous load capability under heatsink-cooled operation |
| VRRM (Peak Reverse Voltage) | 600 V - supports 400 VAC three-phase line inputs with 50 % safety margin |
| VFM (Forward Voltage Drop) | 1.26 V at TJ = 25 °C, IFM = 40 A per junction - determines conduction loss and thermal rise at rated load |
| RthJC (Junction-to-Case) | 1.42 K/W - enables thermal design with known ΔT between die and heatsink surface |
| IFSM (Surge Current) | 360 A (10 ms, 50 Hz, no voltage reapplied) - withstands motor startup inrush without failure |
| VINS (Isolation Voltage) | 2700 V RMS, 1 s - ensures safety compliance for industrial equipment with reinforced insulation |

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 |
|---|---|---|---|
| Vishay VS-26MT80 | Higher VRRM (800 V) but identical IO (25 A), RthJC (1.42 K/W), and D-63 package | Required where line voltage may exceed 400 VAC or transient overvoltage immunity >600 V is mandated | Select VS-26MT80 only if system-level surge testing or regional grid specifications demand higher reverse voltage margin |
| IXYS MDA25F600 | Same 600 V VRRM and 25 A IO, but TO-247-3L package with non-insulated case and higher RthJC (2.0 K/W) | Requires external insulator and larger heatsink; not UL-recognized for end-equipment safety | Choose MDA25F600 only when board-level isolation is already implemented and cost-driven redesign justifies thermal derating |
Compared with VS-26MT80 and MDA25F600, the VS-26MT60 uniquely combines UL E300359 recognition, electrically insulated D-63 packaging, and optimized thermal resistance-making it the preferred choice for certified industrial equipment where safety, compactness, and thermal efficiency are jointly constrained.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-26MT60?
The VS-26MT60 is rated for 25 A DC output current at a maximum case temperature (TC) of 70 °C, as specified in the major ratings table. Operation above this temperature requires derating per the current vs. case temperature curve in Figure 6 of the datasheet. Exceeding 70 °C without adjustment risks thermal runaway and premature failure of the VS-26MT60.
Does the VS-26MT60 require an external heatsink, and what thermal interface material is recommended?
Yes, the VS-26MT60 requires a heatsink for continuous 25 A operation, given its 1.42 K/W junction-to-case thermal resistance. Vishay specifies mounting with a smooth, flat, and greased interface - thermal grease (e.g., Dow Corning TC-5022) or thermally conductive pads meeting 0.2 K/W case-to-heatsink resistance are validated for use with the VS-26MT60.
Is the VS-26MT60 compatible with lead-free reflow soldering processes?
Yes, the VS-26MT60 is qualified for Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures of 260–275 °C, as confirmed in the features section and electrical specifications. This makes the VS-26MT60 compliant with RoHS and suitable for modern SMT assembly lines without requiring special preheat or cooling profiles.
What safety certifications does the VS-26MT60 hold, and how do they impact end-equipment design?
The VS-26MT60 is UL E300359 recognized, confirming compliance with UL 60747-4 for semiconductor devices. This certification allows designers to claim reinforced insulation in final equipment without additional barrier testing, reducing time-to-market for industrial drives and HVAC controllers using the VS-26MT60.
Can the VS-26MT60 be used in single-phase applications, and what limitations apply?
While the VS-26MT60 is configured as a three-phase bridge, it can be used in single-phase full-wave rectification by connecting only two AC terminals (e.g., AC1 and AC2) and leaving AC3 unconnected. However, its 25 A rating applies only under balanced three-phase conduction; single-phase use must be derated per Vishay's application notes to avoid localized overheating of internal junctions in the VS-26MT60.
