Product details
Overview
DDB6U144N16RBOSA1 from Infineon Technologies is a 1600 V repetitive peak reverse voltage, 145 A output current (at TC = 100°C), glass-passivated silicon rectifier diode module in ECONO package with Al₂O₃ internal insulation, designed for industrial AC-DC conversion in motor drives and UPS systems.
For engineers reviewing the DDB6U144N16RBOSA1 datasheet, DDB6U144N16RBOSA1 pinout, DDB6U144N16RBOSA1 application, or DDB6U144N16RBOSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.148 °C/W), surge forward current rating (1200 A), and RMS forward current per chip (100 A) under rectified 120° conduction.
Technical Context
This dual-diode module operates as a single-phase or split-phase bridge arm in high-power rectification circuits. It features glass-passivated Si pellets mounted on an Al₂O₃-ceramic substrate, enabling reliable operation up to 150 °C junction temperature and 2.5 kV RMS insulation test voltage at 50 Hz for 1 minute.
The device delivers 173 A output current at TC = 84°C and supports forced-air cooling (90 L/s) for 173 A at TA = 35°C. Its forward slope resistance is 3.1 mΩ and threshold voltage is 0.75 V at Tvj max, supporting low-conduction-loss DC bus generation.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies a maximum case temperature of 150 °C for short-duration operation, but continuous rated output current (145 A) is defined at TC = 100°C. Operation above 100°C requires linear derating based on the Id vs. TC curve on page 6, with 173 A permitted only at TC = 84°C under specified cooling conditions.
Is DDB6U144N16RBOSA1 suitable for use in a full-bridge rectifier configuration?
Yes - the dual-diode structure (K1/A1 and K2/A2) allows direct implementation as one leg of a full-bridge rectifier. Two modules can form a complete single-phase bridge; three pairs support three-phase six-pulse rectification. The isolated baseplate enables series connection of multiple modules for higher voltage ratings.
Does this module require external snubbers in typical 50/60 Hz rectifier applications?
No external snubbers are required for standard line-frequency rectification due to the device's 1700 V VRSM rating and low reverse recovery charge (not explicitly stated but implied by glass-passivation and 1.65 V vF). However, snubbers may be needed in high-dI/dt switching environments or when used with long cable runs inducing voltage overshoot.
How is thermal resistance measured - per module or per chip?
RthJC is specified both per module (0.148 °C/W) and per chip (0.890 °C/W). The per-module value applies to total power dissipation across both diodes and is used for system-level heatsink sizing; the per-chip value supports individual die thermal modeling in FEA simulations or transient thermal analysis.
