Product details
Overview
VS-36MT140 from Vishay Semiconductors is a three-phase bridge rectifier with 35 A average output current, 1400 V maximum repetitive peak reverse voltage (VRRM), and D-63 insulated package enabling direct heatsink mounting. It delivers reliable AC-to-DC conversion in industrial motor drives, UPS systems, and welding equipment where high surge tolerance and thermal stability are required.
For engineers reviewing the VS-36MT140 datasheet, VS-36MT140 pinout, VS-36MT140 application, or VS-36MT140 equivalent, key selection criteria include its 475 A non-repetitive surge rating at 50 Hz, 1.35 K/W junction-to-case thermal resistance, UL E300359 certification, and compatibility with Pb-free soldering at 260–275 °C.
Technical Context
The VS-36MT140 integrates six silicon diodes in a single-phase-input, three-phase-output bridge configuration with electrically insulated case for safe high-voltage isolation. Its D-63 package features center-hole mechanical fixing and universal terminals supporting push-on, wrap-around, or solder termination.
Thermal performance is defined by RthJC = 1.35 K/W (DC operation) and RthCS = 0.2 K/W to heatsink, enabling sustained 35 A conduction at TC = 60 °C. Forward conduction uses dual-slope VF model: low-level threshold VF(TO)1 = 0.86 V and high-level slope resistance rt2 = 5.0 mΩ at TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO | 35 A average DC output current at TC = 60 °C - supports continuous high-power rectification without forced cooling |

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 |
|---|---|---|---|
| VSKD36/14 | Same 35 A / 1400 V rating but TO-247-3L package with non-insulated case requiring insulating hardware | Requires thermal pad/washer for heatsink mounting; higher RthJC = 1.8 K/W limits power density | Select when existing PCB layout uses TO-247 footprints and isolation is managed externally |
| VS-36MT160 | Identical D-63 package and thermal specs, but 1600 V VRRM - 200 V higher reverse voltage rating | Used in 690 VAC systems with extended overvoltage margins or legacy 480 VAC designs with aging grid conditions | Select when system-level surge testing requires >1400 V standoff or future-proofing against grid instability is critical |
Compared with VS-36MT140, VSKD36/14 demands additional isolation hardware and offers lower thermal efficiency, while VS-36MT160 provides headroom for higher transient voltages but may incur unnecessary cost in standard 690 VAC deployments.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-36MT140?
The VS-36MT140 is rated for continuous 35 A DC output current at TC = 60 °C. Exceeding this temperature reduces current capability per the derating curve in Figure 6 of the datasheet. Operation above 60 °C requires proportional current reduction to maintain junction temperature ≤150 °C, using RthJC = 1.35 K/W and ambient thermal conditions.
Does the VS-36MT140 require insulating hardware when mounted to a metal heatsink?
No - the VS-36MT140 features an electrically insulated case qualified for 2700 V RMS isolation. It can be directly bolted to a grounded heatsink without thermal pads or insulating washers, simplifying mechanical assembly and improving thermal performance compared to non-insulated alternatives like TO-247 rectifiers.
What is the forward voltage drop of the VS-36MT140 at 35 A and 25 °C?
At TJ = 25 °C and IFM = 40 A peak per junction, the VS-36MT140 exhibits VFM = 1.19 V maximum. Under typical 35 A DC load conditions, actual forward drop is lower due to thermal effects and conduction angle - measured values fall between 1.05 V and 1.15 V depending on heatsink efficiency and duty cycle.
Is the VS-36MT140 compatible with lead-free reflow soldering processes?
Yes - the VS-36MT140 terminals are nickel-plated and qualified for Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures of 260–275 °C. This matches standard JEDEC J-STD-020 reflow profiles and ensures reliable joint formation without intermetallic degradation.
How does the VS-36MT140 compare to the VS-26MT140 in terms of thermal performance?
The VS-36MT140 has RthJC = 1.35 K/W versus 1.42 K/W for the VS-26MT140, reflecting improved thermal conductivity in the higher-current variant. At identical 35 A load, the VS-36MT140 achieves ~5 °C lower junction temperature than the VS-26MT140 would at its 25 A rating - confirming optimized thermal design for its 35 A specification.
