Overview
The T1220N26TOFVTXPSA1 is an Electrical Triggered Phase Control 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 repetitive peak off-state voltage (VDRM/VRRM) of 2600V and an average on-state current (ITAVM) of 1220A at 180° electrical sine wave. Key thermal parameters include a maximum junction temperature (Tvj) of 125°C and a thermal resistance RthJC of 18.4 K/kW. The component exhibits a gate trigger time (tq) of 350µs and a non-repetitive peak surge current (ITSM) of 22500A for 10ms.
Feature Summary
- Electrical triggering mechanism designed for phase control applications
- Robust ceramic-insulated disc construction for high power density
- High surge current capability suitable for demanding industrial loads
Applications
- Industrial motor drives
- Resistive heating control systems
- Lighting dimmers
Procurement Notes
Verify the specific ordering suffix XPSA1 against official Infineon documentation to confirm packaging and compliance details. Confirm availability status as distribution channels may list this part as End-of-Life or limited supply. Ensure procurement sources provide valid traceability documents matching the manufacturer's specifications.
Selection Notes
Select this component when a 2600V blocking voltage and 1220A continuous current rating are required in a compact disc form factor. Evaluate the 18.4 K/kW thermal resistance against your heatsinking strategy to maintain junction temperatures below 125°C. Consider the 350µs gate trigger time for compatibility with your firing circuit speed requirements.
Part Context
This part belongs to Infineon's high-power thyristor portfolio, specifically within the T1220N series. It shares the same current rating and physical dimensions with variants like T1220N24TOFVT and T1220N28TOFVT, differing primarily in their voltage ratings of 2400V and 2800V respectively. The XPSA1 suffix denotes a specific packaging or compliance configuration within this family.
Replacement Considerations
Direct replacements include T1220N24TOFVTXPSA1 for lower voltage applications and T1220N28TOFVTXPSA1 for higher voltage margins. Verify that substitute parts match the 75mm disc size and 125°C maximum junction temperature limit.
