Product details
Overview
VS-70MT160PBPBF from Vishay Semiconductors is a three-phase bridge rectifier power module rated for 75 A DC output current at 80 °C case temperature, 1600 V repetitive peak reverse voltage (VRRM), and featuring 3500 VRMS insulation voltage in an MTP package with round pins. It delivers low forward voltage drop (1.45 V at 70 A, 25 °C), low junction-to-case thermal resistance (0.23 K/W per module), and is designed for industrial-grade power conversion systems including UPS, motor drives, and welding equipment.
For engineers reviewing the VS-70MT160PBPBF datasheet, VS-70MT160PBPBF pinout, VS-70MT160PBPBF application, or VS-70MT160PBPBF equivalent, key selection considerations include its 75 A continuous rating, 1600 V blocking capability, MTP round-pin mechanical interface, 3500 VRMS isolation, and thermal performance under 120° rectified conduction angle.
Technical Context
This device integrates six ultrafast recovery diodes in a three-phase full-wave bridge configuration, optimized for high-efficiency AC-to-DC conversion in demanding industrial environments. Its flat thermal path and direct heatsink mounting enable efficient heat dissipation, while the UL-approved (E78996) reinforced insulation supports safety-critical applications requiring galvanic isolation.
The module uses low-slope-resistance silicon die (rt = 9.5 mΩ) and exhibits a threshold voltage VF(TO) of 0.82 V at maximum junction temperature, ensuring stable conduction characteristics across -40 °C to +150 °C operating range. Surge robustness is confirmed by 398 A non-repetitive peak forward current (60 Hz, 8.3 ms) and 724 A²s I²t rating.
Key Specifications

FAQ
What is the maximum continuous DC output current rating for VS-70MT160PBPBF?
The VS-70MT160PBPBF is rated for 75 A DC output current at a case temperature (TC) of 80 °C under 120° rectified conduction angle. This rating assumes proper heatsink mounting with thermal compound and 4 Nm torque. Exceeding 80 °C case temperature requires linear derating per the datasheet nomogram (Fig. 6).
Does VS-70MT160PBPBF support direct mounting to a heatsink without insulating hardware?
Yes, VS-70MT160PBPBF features an electrically insulated metal base qualified for 3500 VRMS isolation, allowing direct bolt-down to grounded heatsinks without additional insulating pads or washers. Mounting torque must be 4 Nm ±10%, and thermal compound with 0.42 W/mK conductivity is recommended.
What is the forward voltage drop specification for VS-70MT160PBPBF at typical operating conditions?
VS-70MT160PBPBF has a maximum forward voltage drop (VFM) of 1.45 V at TJ = 25 °C and peak current Ipk = 70 A (400 μs pulse). At maximum junction temperature (150 °C), the threshold voltage VF(TO) is 0.82 V, with slope resistance rt = 9.5 mΩ, defining the full conduction curve.
How does the pin configuration of VS-70MT160PBPBF differ from flat-pin variants like VS-70MT160PAPBF?
VS-70MT160PBPBF uses round pins (suffix "B") - specifically two Ø1.1 mm round pins per AC phase (U, V, W) plus one Ø1.1 mm pin for DC+, totaling seven terminals. In contrast, VS-70MT160PAPBF uses flat pins (suffix "A") with identical terminal count but rectangular cross-sections optimized for different PCB pad layouts and soldering profiles.
Is VS-70MT160PBPBF certified for industrial safety standards?
Yes, VS-70MT160PBPBF is UL recognized under file E78996 with 3500 VRMS insulation voltage, meeting reinforced insulation requirements per IEC/UL 62368-1. It is explicitly designed and qualified for industrial-level reliability, including operation from -40 °C to +150 °C junction temperature and compliance with Vishay's material categorization standard (doc# 99912).
