DF30NA80S

Bridge Rectifier Overview

The SanRex DF30NA80S is a silicon three-phase rectifier bridge diode module designed for high-performance power conversion. It features a Single In-line Package (SIP) construction with screw mounting capabilities. The device supports a repetitive peak reverse voltage of 800 V and delivers a DC output current of 30 A at a case temperature of 92°C. Key electrical parameters include a maximum forward voltage drop of 1.2 V at 30 A, a surge forward current capability of 400 A (60 Hz), and an isolation breakdown voltage of 2500 V RMS between terminals and the case. The junction-to-case thermal resistance is 0.8 °C/W, and it operates within a junction temperature range of -40°C to +150°C.

Bridge Rectifier Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS directive compliance status through provided documentation. Ensure proper handling procedures are followed due to the semiconductor nature of the device. Validate that the specific ordering suffix matches the required voltage rating before procurement.

Bridge Rectifier Selection Notes

Select this module for applications requiring a three-phase rectifier bridge with a minimum 800 V reverse voltage rating. Ensure the cooling system can maintain the case temperature at or below 92°C to support the rated 30 A DC output current. Verify that the mechanical mounting torque adheres to the recommended 0.8 N·m specification for M3 screws to ensure reliable thermal and electrical contact.

Bridge Rectifier Part Context

This component belongs to the DF30NA series of SIP diode modules manufactured by SanRex Corporation. The series includes variants with different voltage ratings, such as the DF30NA160S, which shares similar physical dimensions and current capabilities but offers higher voltage tolerance. These modules are part of SanRex's discrete semiconductor portfolio focused on power electronics applications.

Bridge Rectifier Replacement Considerations

The DF30NA160S is a direct pin-compatible alternative within the same series offering higher voltage ratings. When substituting, verify that the lower voltage rating of the DF30NA80S meets the circuit requirements if replacing a higher voltage variant. Ensure thermal management remains consistent during any cross-series replacement.
