Product details
Overview
DDB2U40N12W1RFB11BPSA1 from Infineon Technologies is a dual-channel EasyBRIDGE power module integrating two 1200 V / 40 A CoolSiC™ Schottky diodes and an integrated NTC thermistor on an Al₂O₃ substrate, rated for 150 °C junction operation and qualified per IEC 60747/60749/60068 for industrial EV DC fast charger applications.
For engineers reviewing the DDB2U40N12W1RFB11BPSA1 datasheet, DDB2U40N12W1RFB11BPSA1 pinout, DDB2U40N12W1RFB11BPSA1 application, or DDB2U40N12W1RFB11BPSA1 equivalent, this module delivers validated PressFIT interconnect reliability, low stray inductance (10 nH), and thermal resistance of 0.960 K/W per diode for high-efficiency rectification in high-power AC/DC conversion stages.
Technical Context
This module implements a dual-diode topology with independent terminals for each SiC Schottky die, enabling parallel or interleaved rectifier configurations. It features integrated PressFIT solderless contacts and a calibrated NTC (5 kΩ @ 25 °C, B25/100 = 3433 K) for real-time temperature monitoring at the heatsink interface.
The Al₂O₃ ceramic substrate provides 3.0 kV RMS isolation (1 min, 50 Hz), creepage distances ≥6.3 mm, and clearance ≥5.0 mm - meeting reinforced insulation requirements for industrial-grade 1200 V systems operating up to 150 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage SiC rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FF600R12ME4 | 1200 V / 600 A IGBT + FWD module; silicon-based, higher VF (~2.2 V), no integrated NTC. | Designed for inverter output stage, not optimized for high-frequency rectification. | Select only if legacy Si-based gate drive compatibility and lower cost outweigh SiC efficiency gains. |
| IMZ120R030M1H | Discrete 1200 V / 30 mΩ SiC MOSFET; requires external diode and NTC, no PressFIT interface. | Enables custom layout but increases PCB area, assembly steps, and thermal interface complexity. | Choose when board-level integration flexibility and discrete-level optimization are required over module-level reliability. |

FAQ
What is the maximum continuous current rating per diode in DDB2U40N12W1RFB11BPSA1?
The module is rated for 40 A RMS per diode at heatsink temperature TH = 55 °C. Derating applies above this temperature; at TH = 85 °C, the continuous current drops to approximately 25 A RMS per connector pin, as specified in the datasheet's electrical limits table.
Does DDB2U40N12W1RFB11BPSA1 include isolation between terminals and heatsink?
Yes - it provides reinforced insulation with 3.0 kV RMS isolation voltage (1 min, 50 Hz), 11.5 mm creepage distance (terminal-to-heatsink), and 10.0 mm clearance (terminal-to-heatsink), compliant with IEC 61140 Class 1 basic insulation requirements.
Can the integrated NTC be used for closed-loop thermal protection?
Yes - the NTC (5 kΩ @ 25 °C, B25/100 = 3433 K) is factory-calibrated and supports accurate temperature measurement from 25 °C to 150 °C. Its ±5% R100 tolerance enables reliable thermal derating and overtemperature shutdown in DC charger control firmware.
What mechanical mounting method does DDB2U40N12W1RFB11BPSA1 require?
It uses integrated spring-loaded mounting clamps that apply 20–50 N clamping force per clamp onto the heatsink surface. No screws, thermal paste, or additional hardware are needed - the PressFIT terminals and clamps together ensure low-contact-resistance, vibration-resistant mechanical and thermal interface.
