Product details
Overview
VS-40MT160PBPBF from Vishay is a three-phase bridge rectifier power module with 45 A DC output current at 100 °C case temperature, 1600 V repetitive peak reverse voltage (VRRM), and 3500 VRMS insulation rating. It features low forward voltage drop (1.45 V at 40 A, 25 °C), low junction-to-case thermal resistance (0.27 K/W per module), and direct heatsink mounting in a low-profile MTP package with round pins.
For engineers reviewing the VS-40MT160PBPBF datasheet, VS-40MT160PBPBF pinout, VS-40MT160PBPBF application, or VS-40MT160PBPBF equivalent, key selection criteria include industrial-grade surge capability (280 A IFSM at 60 Hz), thermal performance under 120° conduction angle, and PCB-solderable round-pin terminal configuration for high-power motor drives and UPS systems.
Technical Context
This module integrates six silicon diodes in a three-phase full-wave bridge configuration, optimized for continuous conduction in high-current AC/DC conversion. Its flat thermal path and 0.27 K/W RthJC enable efficient heat transfer to external heatsinks without baseplate isolation layers.
The device operates across -40 °C to +150 °C junction temperature range and sustains 3500 VRMS isolation between terminals and heatsink-mounting surface, meeting UL E78996 certification requirements for reinforced insulation in industrial power equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (DC) | 45 A at TC = 100 °C - defines maximum continuous output current under forced-air or heatsink-cooled operation |
| VRRM | 1600 V - maximum repetitive reverse voltage each diode withstands without breakdown |
| VF | 1.45 V at 40 A, 25 °C - forward voltage drop directly impacts conduction losses and thermal design margin |
| IFSM | 280 A at 60 Hz, 8.3 ms - non-repetitive surge rating determines short-circuit robustness in welding or motor-start applications |
| RthJC | 0.27 K/W per module - thermal resistance from junction to case enables accurate heatsink sizing for 150 °C max TJ |
| VINS | 3500 VRMS - isolation voltage certifies safety in grounded-heatsink configurations per UL E78996 |
| TJ Range | -40 °C to +150 °C - extended operating range supports deployment in harsh industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase rectifier bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MDA45-1600 | Higher IFSM (320 A), larger TO-247-3 package, no integrated insulation | Requires external isolation barrier; better suited for custom heatsink-integrated designs | Select when higher surge margin is critical and board-level isolation can be implemented |
| Infineon TD150N16KOF | 150 A rating, 1600 V, press-fit terminals, RthJC = 0.15 K/W | Designed for press-fit assembly into busbars; not PCB-solderable | Select for high-volume busbar-mounted systems where automated press-fit replaces soldering |
Compared with VS-40MT160PBPBF, MDA45-1600 offers greater surge headroom but requires external isolation design effort, while TD150N16KOF delivers superior thermal performance at triple the current rating but lacks round-pin solderability and integrated insulation-making VS-40MT160PBPBF optimal for PCB-based industrial UPS and welding systems needing plug-and-play isolation and thermal management.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-40MT160PBPBF?
The VS-40MT160PBPBF is rated for 45 A DC output current at a maximum case temperature (TC) of 100 °C under 120° conduction angle conditions. Exceeding this temperature requires derating per the current rating nomogram in Vishay document 94538. The junction temperature must remain ≤150 °C, and thermal design must account for RthJC = 0.27 K/W and mounting interface resistance.
Does the VS-40MT160PBPBF require an external heatsink, and what is the recommended mounting torque?
Yes, the VS-40MT160PBPBF requires direct mounting to an external heatsink using its insulated base. Vishay specifies a mounting torque of 4 Nm with lubricated threads and recommends applying thermal compound (0.42 W/mK conductivity) and rechecking torque after 3 hours to accommodate compound spread. The low-profile MTP package is designed for optimal thermal transfer without baseplate isolation layers.
What does the "B" in VS-40MT160PBPBF indicate in the ordering code?
The "B" in VS-40MT160PBPBF denotes the round-pin terminal configuration (as opposed to "A" for flat pins). This version provides enhanced mechanical retention during PCB reflow and thermal cycling, and is specified in Vishay's ordering information table (document 94538, page 7) for applications requiring robust solder-joint reliability in high-vibration environments like welding equipment and motor drives.
Is the VS-40MT160PBPBF certified for safety standards, and which ones?
Yes, the VS-40MT160PBPBF is UL approved under file E78996 and rated for 3500 VRMS insulation voltage per the Insulation Table in document 94538. It complies with RoHS Directive 2002/95/EC (and updated 2011/65/EU), and is designed and qualified for industrial-level reliability. No additional external isolation barriers are required when used per Vishay's mounting guidelines.
How does the forward voltage drop of VS-40MT160PBPBF compare across temperature and current conditions?
The VS-40MT160PBPBF exhibits a typical VF of 1.45 V at 40 A and 25 °C, dropping to approximately 1.28 V at 150 °C due to negative temperature coefficient of silicon diodes. Threshold voltage (VF(TO)) is 0.78 V and slope resistance (rt) is 14.8 mΩ at maximum junction temperature, enabling accurate loss modeling across the full -40 °C to +150 °C operating range.
