Product details
Overview
VS-36MT80 from Vishay Semiconductors is a three-phase bridge rectifier with 35 A average DC output current, 800 V maximum repetitive peak reverse voltage (VRRM), and D-63 package with electrically insulated case. It delivers reliable AC-to-DC conversion in motor drives, industrial power supplies, and welding equipment where high surge tolerance and thermal robustness are required.
For engineers reviewing the VS-36MT80 datasheet, VS-36MT80 pinout, VS-36MT80 application, or VS-36MT80 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 approval, and compatibility with Pb-free soldering at 260–275 °C.
Technical Context
This device integrates six silicon diodes in a single-phase-in, three-phase-out bridge configuration optimized for line-frequency (50/60 Hz) rectification. Its D-63 package features center-hole mounting, nickel-plated terminals, and electrically isolated case enabling direct heatsink attachment without insulating washers.
The VS-36MT80 operates across -55 °C to +150 °C junction temperature range and supports both push-on and solder termination. Its forward voltage drop is characterized by two threshold/slope regions: VF(TO)₁ = 0.86 V and rt₁ = 6.3 mΩ at low conduction, and VF(TO)₂ = 1.03 V and rt₂ = 5.0 mΩ at high conduction-enabling accurate loss modeling under varying load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO | 35 A average DC output current at TC = 60 °C - defines continuous power handling capability under heatsink-cooled operation |
| VRRM | 800 V maximum repetitive peak reverse voltage - sets minimum AC input voltage rating for safe blocking in 3-phase 400 VAC systems |

| RthJC | 1.35 K/W junction-to-case thermal resistance - enables precise heatsink sizing for thermal management in enclosed industrial enclosures |
| VF(TO)₁ / rt1 | 0.86 V threshold + 6.3 mΩ slope - defines conduction loss at light-to-moderate loads (e.g., < 11 A per junction) |
| VINS | 2700 V RMS isolation voltage - certifies dielectric safety between terminals and insulated case for Class I equipment compliance |
Pinout & Package
D-63 package: 24 mm × 28.5 mm × 22 mm body with center mounting hole (Ø5.2 mm), electrically insulated case, and three AC input terminals (AC1, AC2, AC3) plus positive (+) and negative (-) DC output terminals.

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 |
|---|---|---|---|
| VSKD36/08 | Same 35 A / 800 V rating but TO-247-3L package; higher RthJC = 1.8 K/W; no case isolation | Requires external insulator for heatsink mounting; better suited for PCB-mounted designs with space constraints | Select when board-level integration and lower profile are prioritized over thermal efficiency and mechanical mounting simplicity |
| VS-36MT100 | Identical D-63 package and thermal specs, but VRRM = 1000 V; 10% higher forward voltage drop at full load | Targeted at 690 VAC industrial systems; slightly reduced efficiency in 400 VAC applications due to higher VF | Select when system requires higher voltage margin against transients or operation on 690 VAC distribution networks |
Compared with VS-36MT80, VSKD36/08 trades thermal performance and mounting flexibility for smaller footprint, while VS-36MT100 extends voltage capability at minor conduction loss cost-neither is pin-compatible, but both serve overlapping industrial rectification roles.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-36MT80?
The VS-36MT80 is rated for a maximum case temperature (TC) of 60 °C under 35 A DC output current with 120° conduction angle. Exceeding this temperature requires derating per Fig. 6 in the datasheet; operation above 60 °C risks exceeding the 150 °C maximum junction temperature and accelerated wear-out. Thermal design must ensure the heatsink maintains TC ≤ 60 °C at full load.
Does the VS-36MT80 require an insulating pad when mounted to a metal heatsink?
No-the VS-36MT80 features an electrically insulated case certified to 2700 V RMS isolation, allowing direct mounting to grounded heatsinks without thermal interface pads or insulators. This eliminates added thermal resistance and simplifies mechanical assembly. Mounting torque must be maintained at 2.0 Nm ± 10 % using M4 screws.
What is the forward voltage drop specification for VS-36MT80 at 25 °C and rated current?
At TJ = 25 °C and IFM = 40 A peak per junction, the VS-36MT80 exhibits a maximum forward voltage drop (VFM) of 1.19 V. This value reflects worst-case conduction loss under transient conditions; steady-state VF varies between 0.86 V (low-current region) and 1.03 V (high-current region) depending on instantaneous load.
Is the VS-36MT80 compatible with lead-free soldering processes?
Yes-the VS-36MT80 terminals are nickel-plated and qualified for Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures of 260–275 °C. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles, with no pre-bake needed for typical production handling.
How does the VS-36MT80 compare to the VS-26MT80 in terms of thermal performance?
The VS-36MT80 has a lower junction-to-case thermal resistance (RthJC = 1.35 K/W) than the VS-26MT80 (1.42 K/W), reflecting improved internal thermal path design for its higher 35 A rating. However, its maximum case temperature is lower (60 °C vs. 70 °C), meaning thermal design must prioritize heatsink efficiency over simple current scaling when upgrading from VS-26MT80 to VS-36MT80.
