The Fuji 2DI150A-120A is a dual-configuration power diode module rated for 150A continuous forward current and 1200V repetitive peak reverse voltage (VRRM). Built to Fuji Electric's industrial-grade standards, this module delivers low forward voltage drop and high surge current capability in a compact, isolated baseplate package. It is engineered for continuous operation in thermally demanding environments and is compatible with standard heatsink mounting configurations common across industrial inverter and rectifier platforms.

The 2DI150A-120A sees wide deployment in AC motor drive input rectifier stages, regenerative braking circuits, UPS systems, welding power supplies, and DC bus freewheeling applications. Its 1200V blocking voltage provides adequate margin for 690VAC line-side applications, while the 150A current rating supports mid-to-large frame drive topologies. Energy storage, induction heating, and industrial power conditioning equipment frequently rely on this module series for dependable front-end rectification and flyback protection.

Quick Reference: 2DI150A-120A

Key Features of the 2DI150A-120A:

• Dual diode configuration in a single isolated module package simplifies PCB and busbar layout
• 1200V VRRM provides safe operating margin on 480V and 690VAC three-phase input stages
• 150A average forward current (IF(AV)) supports mid-to-large frame industrial drive platforms
• Low forward voltage drop (VF) minimizes conduction losses and reduces heatsink thermal requirements
• High surge current (IFSM) rating accommodates inrush and fault transient conditions without device failure
• Isolated copper baseplate construction enables direct heatsink mounting with standard thermal interface materials

With a factory lead time of 99 weeks for new production, the 2DI150A-120A represents exactly the kind of long-lead, hard-to-plan component that can halt a project or extend a machine outage indefinitely. Procurement teams supporting aging drive platforms or legacy industrial equipment cannot afford to rely solely on OEM channels for this part. ATI maintains inventory of the 2DI150A-120A as new OEM stock, providing an immediate alternative to extended factory queues for both emergency replacements and planned MRO replenishment strategies.
