Overview
The T1900N16TOFVTXPSA1 is an Electrical Triggered Phase Control (ETPCT) thyristor manufactured by Infineon Technologies. It features a disc package with a diameter of 75mm and height of 26mm, utilizing ceramic insulation. The device supports a maximum repetitive peak reverse voltage (VRRM) and maximum repetitive peak forward blocking voltage (VDRM) of 1600V. The average on-state current (ITAVM) at 180° electrical sine wave is 1810A, while the non-repetitive peak surge on-state current (ITSM) for 10ms duration at maximum junction temperature is 30700A. The maximum thermal resistance from junction to case (RthJC) is 18.4 K/kW. The gate trigger time (tq) is 270µs, and the maximum operating junction temperature (Tvj) is 135°C.
Feature Summary
- Electrical triggering mechanism eliminates the need for external pulse transformers.
- Robust construction with sealed ceramic housing for high reliability.
- High surge current capability suitable for demanding power applications.
Applications
- High-power industrial motor drives
- HVDC transmission systems
- Static VAR compensators
Procurement Notes
Verify the specific ordering suffix against official Infineon documentation to ensure correct packaging and testing variants. Confirm mechanical dimensions and clamp force requirements match the application design before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component based on its 1600V blocking capability and 1810A average current rating. Ensure the cooling system can handle the specified thermal resistance of 18.4 K/kW. Verify that the gate drive circuitry meets the electrical triggering requirements for reliable turn-on at the specified trigger time.
Part Context
This part belongs to the T1900N series of phase control thyristors from Infineon. These devices are designed for high-power AC/DC conversion applications requiring robust performance and long-term stability in harsh environments.
Replacement Considerations
Direct replacements must match the 1600V rating, 1810A current capacity, and disc package dimensions. Consult Infineon's cross-reference guides for equivalent ETPCT devices within the same or higher current classes.
