Product details
Overview
VS-70MT160PAPBF from Vishay Semiconductors is a three-phase bridge rectifier 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 flat-pin package. 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 power conversion systems requiring high reliability and direct heatsink mounting.
For engineers reviewing the VS-70MT160PAPBF datasheet, VS-70MT160PAPBF pinout, VS-70MT160PAPBF application, or VS-70MT160PAPBF equivalent, key selection criteria include its 75 A continuous rating, 1600 V blocking capability, 3500 VRMS isolation, MTP flat-pin mechanical interface, and suitability for UPS, motor drives, and welding equipment where compact three-phase rectification with low thermal impedance is critical.
Technical Context
This device integrates six ultrafast recovery diodes in a common-cathode/common-anode three-phase full-wave bridge configuration, enabling efficient AC-to-DC conversion in industrial inverters and SMPS. Its MTP package uses flat pins for PCB soldering and direct heatsink attachment via two M4 mounting holes, with thermal path optimized for low RthJC (0.23 K/W) and RthCS (0.1 K/W).
The module supports 50/60 Hz line frequencies and withstands non-repetitive surge currents up to 398 A (60 Hz, 8.3 ms) and I2t of 660 A2s (60 Hz, 8.3 ms, no voltage reapplied). It operates across -40 °C to +150 °C junction temperature range and meets UL E78996 certification for insulation safety.

FAQ
What is the maximum continuous DC output current rating for VS-70MT160PAPBF?
The VS-70MT160PAPBF is rated for 75 A maximum DC output current at a case temperature of 80 °C under 120° rectification conduction angle. This rating assumes proper heatsinking with ≤0.1 K/W case-to-heatsink thermal resistance and ambient conditions within the -40 °C to +150 °C junction temperature range. Derating is required above 80 °C case temperature per the datasheet nomogram.
Does VS-70MT160PAPBF have built-in electrical isolation, and what is its rating?
Yes, the VS-70MT160PAPBF features integrated reinforced insulation with a 3500 VRMS isolation voltage rating between all terminals and the baseplate, verified per UL E78996. This allows safe use in grounded or floating DC bus architectures without additional isolation barriers, supporting Class I and II system safety requirements in industrial equipment.
What is the forward voltage drop of VS-70MT160PAPBF at typical operating conditions?
The VS-70MT160PAPBF exhibits a maximum forward voltage drop (VFM) of 1.45 V at TJ = 25 °C, with a 70 A pulsed test current (tp = 400 μs). At elevated junction temperatures (e.g., 150 °C), VF decreases slightly due to semiconductor physics, but the threshold voltage (VF(TO)) is 0.82 V and slope resistance (rt) is 9.5 mΩ - enabling accurate loss modeling across operating conditions.
How is thermal management implemented in the VS-70MT160PAPBF package?
The VS-70MT160PAPBF uses a metal-baseplate MTP package with direct-mount architecture: the baseplate serves as both the DC negative return path and primary thermal interface. With a specified RthJC of 0.23 K/W (per module) and RthCS of 0.1 K/W (with thermal compound), it requires only 4 N·m mounting torque to a flat, greased heatsink - eliminating need for complex thermal interface materials or secondary heat spreaders.
Is VS-70MT160PAPBF RoHS-compliant and lead-free?
Yes, the "PbF" suffix in VS-70MT160PAPBF explicitly denotes lead-free (RoHS-compliant) construction per EU Directive 2011/65/EU and Vishay's material categorization standard (doc. 99912). All terminations, internal interconnects, and packaging materials meet strict heavy-metal restrictions, with full compliance documentation available through Vishay's quality portal.
