Bridge Rectifier datasheet and documents for DBI25-12A
Bridge Rectifier Overview
The Diotec Semiconductor DBI25-12A is a three-phase diode bridge rectifier designed for industrial power applications. It features an average forward current rating of 40 A at an ambient temperature of 85°C and 25 A at 115°C case temperature. The device supports a repetitive peak reverse voltage of 1200 V with a maximum forward voltage of 1.05 V at 12.5 A. It withstands a peak forward surge current of 370 A at 50 Hz and 390 A at 60 Hz. Operating within a junction temperature range of -50°C to +175°C, it utilizes a single inline isolated package suitable for heatsink mounting.
Bridge Rectifier Feature Summary
- High-admissible repetitive reverse voltage capability up to 1200 V
- Single inline isolated case design facilitating easy PCB assembly
- Capable of operation freestanding or mounted directly on a heatsink
- Provides high forward surge current handling for robust performance
Bridge Rectifier Applications
- Industrial power supplies
- Input stages of frequency inverters
- Electric vehicle (EV) chargers
- Electric drives and generators
Bridge Rectifier Procurement Notes
Verify the specific suffix '12A' corresponds to the 1200 V rating when ordering. Confirm compliance with RoHS and ELV directives as stated in the datasheet. Ensure mounting torque adheres to the specified M4 screw requirements. Check for recent product change notices regarding package revisions.
Bridge Rectifier Selection Notes
Select this component for three-phase rectification requiring high voltage isolation. Evaluate thermal management needs based on the 4.3 K/W junction-to-case resistance. Ensure the application current does not exceed the 40 A limit at 85°C ambient conditions. Verify compatibility with standard through-hole mounting techniques.
Bridge Rectifier Part Context
This part belongs to the DBI25 series of three-phase bridge rectifiers from Diotec Semiconductor. The series includes variants ranging from 800 V to 1800 V reverse voltage ratings. These components are engineered for commercial and industrial grade reliability, offering standardized dimensions for consistent integration into various power electronics designs.
Bridge Rectifier Replacement Considerations
PCN128 indicates that the DBI20-xxB series has been replaced by the DBI25-xxA series. Verify if the DBI25-12A serves as a direct functional replacement for legacy DBI20 models in existing designs.
