Product details
Overview
VS-160MT80KPBF from Vishay Semiconductors is a three-phase bridge rectifier power module rated for 160 A average output current and 800 V maximum repetitive peak reverse voltage (VRRM), housed in an electrically insulated MTK package with 4000 VRMS isolation. It delivers low forward voltage drop (1.49 V at 200 A, 25 °C) and high surge capability (1500 A at 60 Hz, 8.3 ms), enabling robust operation in industrial motor drives and UPS systems.
For engineers reviewing the VS-160MT80KPBF datasheet, VS-160MT80KPBF pinout, VS-160MT80KPBF application, or VS-160MT80KPBF equivalent, key selection criteria include thermal resistance (RthJC = 0.12 K/W per module), I²t fusing rating (9300 A²s at 8.3 ms), junction temperature range (–40 to +150 °C), and UL E78996 approval for safety-critical installations.
Technical Context
This module integrates six silicon diodes in a three-phase full-wave bridge configuration, optimized for 120° rectification conduction angle. Its MTK package features electrically insulated copper baseplate, fast-on terminals (type 110), and M5 mounting screws - enabling direct heatsink attachment with low thermal resistance (RthCS = 0.03 K/W).
The device operates across –40 °C to +150 °C junction temperature, with dual threshold voltage levels (VT(TO)₁ = 0.81 V, VT(TO)₂ = 1.04 V) and forward slope resistances (rf₁ = 3.52 mΩ, rf₂ = 3.13 mΩ) that define conduction behavior under partial and full-load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (DC Output Current) | 160 A at TC = 60 °C - defines continuous load capacity under forced-cooled industrial conditions |
| VRRM | 800 V - maximum reverse voltage sustainable without breakdown; sets minimum system DC bus rating |
| IFSM (60 Hz) | 1500 A - peak non-repetitive surge current tolerance for short-circuit protection coordination |
| I²t (8.3 ms) | 9300 A²s - fusing energy limit used to size upstream fuses or circuit breakers |
| RthJC (per module) | 0.12 K/W - thermal resistance from junction to case; determines heatsink sizing for 160 A operation |
| VFM (200 A, 25 °C) | 1.49 V - forward voltage drop at rated pulse current; directly impacts conduction loss and thermal design |
| VISOL | 4000 VRMS - isolation voltage between terminals and case; satisfies reinforced insulation requirements |
Pinout & Package
The VS-160MT80KPBF uses the MTK package: 94 mm × 75 mm × 35 mm insulated metal-base module with three AC input terminals (A, B, C), one positive DC output (+), one negative DC output (–), and mounting screw holes (M5). Fast-on tabs (2.8 × 0.8 mm, type 110) provide low-inductance connections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A, B, C | AC Input Phases | Three-phase AC line inputs to full-wave bridge; symmetrical layout minimizes parasitic inductance |
| + | DC Positive Output | Anode-side common output node; connects to DC bus capacitor positive terminal |
| – | DC Negative Output | Cathode-side common output node; serves as return path and reference for gate drivers/sensors |
Key Features
| Feature | Design Value |

| UL E78996 Approval | Validated insulation system meeting UL 60950-1/62368-1 for industrial equipment safety certification |
| Electrically Insulated Case | Dielectric barrier enables direct mounting on grounded heatsinks without additional isolation hardware |
| Industry-Standard INT-A-PAK Compatibility | Footprint and mounting interface match legacy INT-A-PAK modules - simplifies upgrade paths |
| High Power Density | 160 A output in 94 × 75 mm footprint supports compact inverter designs with minimal board area |
| Low RthJC (0.12 K/W) | Enables higher sustained current or lower heatsink thermal resistance - reduces system cooling cost |

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 |
|---|---|---|---|
| IXYS MDA160-16N1 | 160 A / 1600 V; TO-247-3L discrete diode module; no integrated isolation; RthJC = 0.25 K/W | Requires external insulating pad and larger heatsink; suitable where higher VRRM margin is needed | Select when system requires >1200 V reverse blocking or discrete layout flexibility |
| Vishay VS-160MT120KPBF | Same MTK package and 160 A rating; VRRM = 1200 V; higher VFM (1.58 V); identical pinout and thermal specs | Direct drop-in replacement where 1200 V reverse margin is required (e.g., 690 VAC systems) | Choose for 690 VAC input or higher transient immunity; same mechanical fit and thermal management |
Compared with VS-160MT80KPBF, the IXYS MDA160-16N1 offers higher voltage rating but demands added isolation and thermal design effort, while the VS-160MT120KPBF provides identical form-factor compatibility with enhanced reverse voltage headroom at slightly higher conduction loss.

FAQ
What is the maximum junction temperature rating for VS-160MT80KPBF?
The VS-160MT80KPBF has a maximum junction operating temperature of +150 °C and a storage temperature range of –40 to +150 °C. This rating allows operation in harsh industrial environments such as enclosed motor control cabinets or outdoor UPS enclosures, provided thermal design maintains TJ ≤ 150 °C under worst-case load and ambient conditions. The device's RthJC = 0.12 K/W per module enables accurate junction temperature prediction using measured case temperature.
Does VS-160MT80KPBF require external insulation when mounted to a heatsink?
No - the VS-160MT80KPBF features an electrically insulated case with 4000 VRMS isolation, allowing direct mounting to grounded heatsinks without additional insulating pads or hardware. Its MTK package uses a ceramic-filled epoxy barrier between the copper baseplate and internal die, certified under UL E78996. Mounting torque must be maintained at 4–6 Nm with thermal compound to ensure both thermal performance and dielectric integrity.
What is the forward voltage drop specification for VS-160MT80KPBF at rated current?
The VS-160MT80KPBF specifies VFM = 1.49 V at Ipk = 200 A, TJ = 25 °C, tp = 400 μs (single junction). At full-rated 160 A DC output with 120° conduction, typical forward drop is ~1.55 V at TJ = 125 °C. This low VFM contributes to reduced conduction losses - critical for efficiency in high-power applications like 50 kW motor drives where even 0.1 V reduction lowers total loss by ~12 W per module.
Can VS-160MT80KPBF be used in 690 VAC systems?
No - the VS-160MT80KPBF has VRRM = 800 V, which provides insufficient margin for 690 VAC systems (peak line-to-line voltage ≈ 975 V). For 690 VAC input, Vishay recommends VS-160MT120KPBF (VRRM = 1200 V) or VS-160MT140KPBF (VRRM = 1400 V), both sharing identical MTK packaging, pinout, and thermal characteristics. Using VS-160MT80KPBF in 690 VAC risks premature reverse breakdown during transients or voltage imbalance.
What mounting hardware is required for VS-160MT80KPBF installation?
The VS-160MT80KPBF requires M5 × 0.8 screws (length 10 mm), lubricated threads, and mounting torque of 4–6 Nm to heatsink. A thermal interface material is strongly recommended; Vishay specifies greased mounting surface for RthCS = 0.03 K/W. Fast-on terminals accept 2.8 × 0.8 mm (type 110) connectors. Optional barriers (document 95172) and mounting kits are available separately via Vishay's ordering portal.
