DF20NA160 S

Bridge Rectifier Overview

The SanRex DF20NA160S is a single in-line package (SIP) diode module designed for three-phase rectifier bridge applications. It features silicon technology with a repetitive peak reverse voltage of 1600 V and a non-repetitive peak reverse voltage of 1700 V. The module provides a DC output current of 20 A at a case temperature of 111°C, with a maximum forward voltage drop of 1.2 V at 25°C and 20 A. It supports a surge forward current of 350 A for one cycle at 50/60 Hz. The junction-to-case thermal resistance is 0.8 °C/W, and it offers an isolation breakdown voltage of 2500 V RMS between terminals and the case. Operating and storage temperatures range from -40°C to +150°C.

Bridge Rectifier Feature Summary

• Single in-line package design for compact mounting
• Very low forward voltage drop for efficiency
• High surge current capability for robust operation
• 2500V isolation rating for safety

Bridge Rectifier Applications

• Battery chargers
• Power supplies
• Motor controls
• Air conditioner units
• Home appliances

Bridge Rectifier Procurement Notes

Verify the specific suffix 'S' against official documentation to confirm pinout and packaging details. Ensure thermal management meets the 111°C case temperature requirement for rated current. Confirm RoHS compliance status through the manufacturer's latest declaration. Check mounting torque specifications for M3 screws to prevent mechanical failure during installation.

Bridge Rectifier Selection Notes

Select this module for three-phase AC-DC conversion where space is limited due to its SIP form factor. Ensure the system can handle the 1600V reverse voltage rating under peak conditions. Verify that the cooling solution maintains the case temperature below 111°C to sustain the 20A continuous current rating without derating.

Bridge Rectifier Part Context

This component belongs to the DF20NA series of SIP diode modules manufactured by SanRex. It shares the same physical package and general electrical characteristics as the DF20NA80S variant, differing primarily in its higher voltage blocking capabilities. The series is engineered for industrial power electronics requiring reliable three-phase rectification.
