Product details
Overview
T533N80TOHXPSA1 from Infineon Technologies is a light-triggered phase-control thyristor designed for high-voltage, high-current medium-voltage power conversion systems. It delivers 540 A average on-state current at 85°C case temperature, 8000 V repetitive peak reverse voltage, and 10.5 kA 10 ms surge current capability. Its integrated break-over diode enables optical triggering in crowbar and static var compensation (SVC) applications.
For engineers reviewing the T533N80TOHXPSA1 datasheet, T533N80TOHXPSA1 pinout, T533N80TOHXPSA1 application, or T533N80TOHXPSA1 equivalent, key selection criteria include verified 76 mm diameter press-pack package, 20 K/kW junction-to-case thermal resistance, 300 A/µs critical di/dt rating, and confirmed gate trigger light power ≤40 mW at 25°C.
Technical Context
This thyristor operates as a line-commutated, light-triggered switching device with full 50/60 Hz blocking capability across –40°C to +120°C junction temperature range. Its design integrates a monolithic silicon pellet under mechanical clamping (15–24 kN), enabling direct optical gate control without electrical isolation components.
The device exhibits 1.26 V threshold voltage and 1.47 mΩ slope resistance at maximum junction temperature, supporting stable conduction under high DC blocking stress and pulsed power duty cycles. Its 650 µs circuit commutated turn-off time and 10 mAs recovered charge are validated under 100 V reverse recovery conditions with controlled di/dt.

Equivalent & Alternatives
The following parts are listed as comparable options for similar light-triggered thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| T533N80TOF | Same voltage/current ratings but lacks integrated break-over diode; requires external overvoltage protection | Suitable for non-critical crowbar functions where external protection is acceptable | Select only if optical triggering and 8000 V blocking are primary needs and break-over functionality is implemented externally |
| TT900N14KOF | 1400 V VRRM, 900 A ITAVM; lower voltage class, higher current, different package (isolated stud) | Applicable in low-voltage industrial inverters, not medium-voltage grid interfaces | Choose only for 1.1–1.7 kV AC systems requiring higher average current and electrical isolation |
Compared with T533N80TOF and TT900N14KOF, the T533N80TOHXPSA1 uniquely combines 8 kV blocking, optical triggering, and integrated break-over protection in a press-pack format-enabling compact, high-reliability crowbar and SVC designs without auxiliary protection circuitry.

FAQ
What is the required gate trigger light power for reliable turn-on?
The maximum gate trigger light power is 40 mW at 25°C with 40 V anode-cathode voltage. This value is measured using infrared light pulses meeting IEC 60747-6 requirements. Lower power may suffice at reduced junction temperatures, but 40 mW ensures margin across the full –40°C to +120°C operating range.
Can this thyristor be used with single-sided cooling?
No. The 20.0 K/kW RthJC rating applies exclusively to two-sided cooling. With anode-only or cathode-only cooling, RthJC degrades to 30.5 K/kW or 50.0 K/kW respectively-requiring derating of ITAVM by up to 35%. Mechanical clamping must ensure uniform contact across both sides for thermal performance compliance.
What is the significance of the "H" and "O" letters in the type code?
The 5th letter "H" denotes 2000 V/µs critical dv/dt rating; the 4th letter "O" indicates 650 µs typical circuit commutated turn-off time. These identifiers are defined in Infineon's shortform catalog and correlate directly to validated test conditions in the technical information document revision 3.0.
How does the integrated break-over diode function during overvoltage events?
The integrated break-over diode triggers conduction when reverse voltage exceeds 7500 V (VBO min), independently of gate light input. This provides autonomous crowbar action during lightning surges or switching transients, bypassing the need for external voltage-sensing and firing circuits while maintaining full 8000 V VRRM rating under normal operation.
