Overview
The SanRex DD300KB160 is a power diode module featuring two series-connected chips with an electrically isolated mounting base. It supports a repetitive peak reverse voltage of 1600V and a non-repetitive peak reverse voltage of 1700V. The average forward current rating is 300A at Tc=91°C, with an RMS forward current of 465A. Surge forward current reaches 6000A for one half-cycle at 60Hz. Maximum junction-to-case thermal impedance is 0.14°C/W, and the isolation breakdown voltage is 2500Vrms.
Feature Summary
- Isolated mounting base enables simple heatsink construction
- Two elements in a package facilitate single and three-phase bridge connections
- Highly reliable glass passivated chips ensure durability
- High surge current capability for robust performance
Applications
- Various rectifier circuits
- Battery chargers
- DC motor drives
Procurement Notes
Verify the specific part number suffix against official San Rex documentation to confirm exact electrical ratings and mechanical dimensions. Ensure compatibility with recommended mounting torque values of 1.5-2.5 N·m for M5 terminals and 8.8-10.0 N·m for M8 terminals. Confirm thermal management requirements align with the specified junction temperature range of -40 to +150°C.
Selection Notes
Select this module for applications requiring high voltage blocking capabilities up to 1600V and significant current handling. The isolated base design simplifies thermal interface integration. Consider the 6000A surge rating for systems with high inrush currents. Verify that the operating environment stays within the specified storage and junction temperature limits.
Part Context
This component belongs to the DD300KB series of power diode modules from San Rex Corporation. The series offers various voltage ratings, including 400V, 800V, 1200V, and 1600V variants. All models share a common physical footprint and internal architecture with two series-connected diode chips, differing primarily in their voltage blocking specifications.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided datasheet. When evaluating alternatives, match the 1600V VRRM, 300A IF(AV), and TO-240AA-like package dimensions. Ensure the replacement device also features an isolated mounting base and comparable surge current ratings.
