DF100NB160

Bridge Rectifier Overview

The SanRex DF100NB160 is a silicon-based, isolated three-phase diode bridge module designed for high-power rectification. It features a maximum repetitive peak reverse voltage of 1600 V and an average output current rating of 100 A per leg at a case temperature of 98°C. The forward voltage ranges from 1.16 V to 1.35 V at 100 A, with a typical junction-to-case thermal resistance of 0.20 °C/W. The device supports a non-repetitive surge forward current of 4100 A and operates within a junction temperature range of -40°C to +150°C. It utilizes a transfer molding package and includes dual terminals for solder mounting.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact electrical ratings and packaging details. Ensure that the mounting torque specifications are strictly followed during installation to maintain thermal performance and mechanical integrity. Cross-reference the isolation voltage requirements with the system design parameters before procurement.

Bridge Rectifier Selection Notes

Select this component when a compact, high-reliability three-phase bridge is required for industrial applications. The low thermal resistance and improved power cycling make it suitable for environments with significant thermal stress. Verify that the 1600V reverse voltage rating exceeds the peak line-to-line voltage of the AC input source to ensure safe operation under all conditions.

Bridge Rectifier Part Context

This module belongs to the SanRex DF series of discrete semiconductor diode modules. It is engineered as a replacement for older generation bridge rectifiers, offering a significantly smaller footprint while maintaining or improving current handling capabilities. The series is characterized by its use of advanced molding techniques to enhance long-term reliability in power conversion systems.
