DD171N14K Description

Short technical summary and product information.

This Rectifier Diode Module from Eupec, part number DD171N14K, is engineered for robust performance in demanding electrical environments. It boasts a high repetitive peak reverse voltage rating of 1600V and a non-repetitive peak reverse voltage of 1700V, ensuring reliability under transient conditions.

 

The module can handle a maximum RMS on-state current of 270A and an average on-state current of 171A at 100°C. Its surge current capability is 6600A for a 10ms pulse at 25°C, with an I²t value of 218,000 A²s. The on-state voltage is a maximum of 1.26V at 500A, with a threshold voltage of 0.75V and a slope resistance of 0.8 mΩ.

 

Thermal management is critical, with a maximum junction temperature of 150°C and operating temperatures ranging from -40°C to 150°C. Thermal resistance from junction to case is 0.126°C/W (DC, per module) and case to heatsink is 0.03°C/W (per module).

 

Mechanically, the module requires a mounting torque of 6 Nm for mechanical connections and 6 Nm for electrical connections. It weighs approximately 310g and has a creepage distance of 15mm. The module is suitable for through-hole mounting.
