Product details
Overview
VS-36MT40 from Vishay Semiconductors is a three-phase bridge rectifier with 35 A average DC output current, 400 V maximum repetitive peak reverse voltage (VRRM), and D-63 package featuring electrically insulated case and center-hole mounting. It delivers reliable AC-to-DC conversion in industrial motor drives and HVAC power supplies where thermal management and mechanical robustness are critical.
For engineers reviewing the VS-36MT40 datasheet, VS-36MT40 pinout, VS-36MT40 application, or VS-36MT40 equivalent, key selection criteria include its 35 A IO rating at TC = 60 °C, 1.35 K/W junction-to-case thermal resistance, UL E300359 approval, and compatibility with Pb-free soldering (SAC305, 260–275 °C).
Technical Context
This device integrates six diodes in a single-phase-input, three-phase-output bridge configuration optimized for 50/60 Hz line-frequency rectification. Its D-63 package uses molded epoxy encapsulation with electrically isolated metal baseplate, enabling direct heatsink mounting without insulating washers.
The VS-36MT40 exhibits dual forward voltage characteristics: VF(TO)1 = 0.86 V and rt1 = 6.3 mΩ at low conduction levels, and VF(TO)2 = 1.03 V with rt2 = 5.0 mΩ under full-load conditions - enabling accurate power loss modeling across operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (DC Output Current) | 35 A at TC = 60 °C - defines continuous load capability with forced-air or heatsink cooling |
| VRRM | 400 V - maximum reverse voltage per diode before breakdown; matches 230 VAC 3-phase line with safety margin |
| IFSM (t = 8.3 ms) | 500 A - surge withstand for one 60 Hz half-cycle; supports motor-start inrush and fault clearing |
| RthJC | 1.35 K/W - enables thermal design with ≤45 W total power loss at TJ = 150 °C |
| VFM (TJ = 25 °C) | 1.19 V at 40 A peak per junction - determines conduction loss and heatsink sizing in steady-state operation |
| IRRM | 100 µA at rated VRRM - ensures minimal leakage in high-impedance sensing or standby circuits |
| VINS | 2700 V RMS - provides reinforced isolation between terminals and heatsink-mounted case |
Pinout & Package
D-63 package: 24 mm × 28.5 mm × 22 mm molded epoxy body with electrically insulated metal baseplate, center mounting hole (Ø5.2 mm), and three AC input terminals (AC1, AC2, AC3) plus positive (+) and negative (–) DC output terminals. Mounting torque: 2.0 Nm (M4 screw).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 |
|---|---|---|---|
| VSKD36/04 | Same 35 A IO and 400 V VRRM, but TO-247-3L package with non-insulated case requiring thermal pad | Requires additional insulation hardware and higher PCB footprint; lower thermal resistance (RthJC = 0.8 K/W) but more complex mounting | Select when board-level thermal performance outweighs mechanical simplicity and safety certification needs |
| VS-26MT40 | 25 A IO rating, identical VRRM (400 V), same D-63 package and pinout - direct drop-in with derated current capacity | Suitable for lower-power 3-phase systems where 35 A headroom is unnecessary; shares identical mounting and isolation features | Choose for cost-sensitive designs with verified 25 A load margins and unchanged mechanical integration |
Compared with VS-36MT40, VSKD36/04 offers superior thermal performance but adds assembly complexity and safety validation overhead, while VS-26MT40 provides identical form-factor compatibility at reduced current capability - enabling staged BOM optimization without layout change.

FAQ
What is the maximum case temperature for continuous operation of the VS-36MT40?
The VS-36MT40 is rated for continuous operation with a maximum case temperature (TC) of 60 °C at its full 35 A DC output current. Exceeding this temperature requires derating per the current vs. case temperature curve in Figure 6 of the datasheet. Maintaining TC ≤ 60 °C ensures junction temperature remains within the safe limit of 150 °C under typical thermal interface conditions.
Does the VS-36MT40 require an insulating pad when mounted to a heatsink?
No, the VS-36MT40 does not require an insulating pad because its D-63 package features an electrically insulated metal baseplate. This design allows direct mounting to grounded heatsinks while maintaining 2700 V RMS isolation between terminals and the heatsink surface - a key advantage over non-insulated alternatives like TO-247 devices.
What soldering profile is recommended for the VS-36MT40?
The VS-36MT40 is qualified for Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures between 260 °C and 275 °C. Reflow profiles must comply with JEDEC J-STD-020, with time above liquidus (TAL) limited to ≤60 seconds. The device's terminals are nickel-plated to ensure wetting reliability and intermetallic formation control.
How does the VS-36MT40 compare to the VS-26MT40 in terms of thermal performance?
The VS-36MT40 has a slightly lower junction-to-case thermal resistance (RthJC = 1.35 K/W) than the VS-26MT40 (1.42 K/W), reflecting optimized internal construction for higher current. Both share identical D-63 packaging and mounting interface, so heatsink selection and thermal interface materials can be reused - only the current derating curve differs.
Is the VS-36MT40 certified for use in UL-listed end equipment?
Yes, the VS-36MT40 is UL E300359 approved, meaning it meets UL 60747-1 and UL 60950-1 requirements for insulated semiconductor devices. This certification permits direct use in UL-listed industrial power supplies and motor drives without requiring additional system-level isolation barriers or creepage distance verification.
