TD250N14KOFHPSA1

SCRs - Modules Overview

The Infineon Technologies TD250N14KOFHPSA1 is a phase control thyristor module utilizing pressure contact technology. It features an electrically insulated base plate and operates within a junction temperature range of -40°C to +125°C. The device supports repetitive peak forward and reverse voltages (VDRM/VRRM) from 1200 V to 1800 V, with the specific 1400 V variant providing a maximum RMS on-state current (ITRMSM) of 410 A and an average on-state current (ITAVM) of 250 A at TC=85°C. Surge current capacity reaches 9100 A for 10 ms at 25°C. Key electrical parameters include a threshold voltage (VT0) of 0.8 V, slope resistance (rT) of 0.7 mΩ, and a thermal resistance (RthJC) of 0.124 K/W per arm.

SCRs - Modules Procurement Notes

Verify the exact voltage rating suffix corresponding to the required blocking voltage (e.g., 1400 V). Confirm that the ordering suffix matches the specific configuration needed for your application. Ensure compliance with RoHS directives and check for pre-applied thermal interface material availability if specified in the order details.

SCRs - Modules Selection Notes

Select based on the required repetitive peak forward/reverse voltage (VDRM/VRRM) and the necessary average on-state current (ITAVM) at the intended case temperature. Consider the critical rate of rise of on-state current ((diT/dt)cr) and surge current ratings for fault protection requirements. Evaluate thermal management needs using the provided RthJC values.
