Bridge Rectifier Procurement Notes
Verify the specific ordering suffix DT8 against official IXYS documentation to confirm terminal configuration and packaging details. Ensure that the required blocking voltage matches the 1600 V specification for this part number. Cross-reference datasheet revision dates to confirm compliance with current manufacturing standards before finalizing procurement orders.
Bridge Rectifier Selection Notes
Select this component when a three-phase rectification solution requires 1600 V blocking capability and moderate current handling around 18 A. Consider the semi-fast diode characteristics if reverse recovery times near 1.5 µs are acceptable for the switching frequency. Verify that the mechanical dimensions and fast-on terminal spacing align with the available PCB or busbar layout constraints.
Bridge Rectifier Part Context
This module belongs to the VUO 18 series of three-phase rectifier bridges from IXYS. The series includes variants with different voltage ratings, such as the VUO18-12DT8 for 1200 V and VUO18-14DT8 for 1400 V applications. All variants share similar physical dimensions and thermal characteristics while differing in their maximum repetitive peak reverse voltage specifications.
Bridge Rectifier Replacement Considerations
Direct replacements must match the 1600 V rating, 18 A current capacity, and 3000 V isolation voltage. Verify that substitute components support quarter-inch fast-on terminals or provide compatible mechanical interfaces. Ensure the replacement diodes exhibit comparable reverse recovery times and forward voltage drops to maintain system efficiency.
