Product details
Overview
T2563NH80TOHXOSA1 from Infineon Technologies is a light-triggered phase-control thyristor designed for high-power crowbar and pulsed power applications. It delivers 2300 A average on-state current at 85°C case temperature, 8000 V repetitive peak reverse voltage, and 93 kA surge current capability with 5000 A/µs critical di/dt rating.
For engineers reviewing the T2563NH80TOHXOSA1 datasheet, T2563NH80TOHXOSA1 pinout, T2563NH80TOHXOSA1 application, or T2563NH80TOHXOSA1 equivalent, key selection criteria include clamping force range (90–130 kN), junction-to-case thermal resistance (4.5 K/kW), and gate trigger light power requirement (≤40 mW).
Technical Context
This thyristor uses direct optical triggering with an integrated break-over diode for precise, jitter-free turn-on without external gate drivers. Its blocking capability is rated at 8000 V (VRRM) across -40°C to +120°C operating temperature, with full 50/60 Hz AC blocking stability and high DC blocking margin.
The device features extreme di/dt immunity (5000 A/µs) and low conduction losses-typical on-state voltage is 2.75 V at 5000 A and 120°C junction temperature, supported by a slope resistance of 0.326 mΩ and threshold voltage of 1.12 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 8000 V - maximum repetitive reverse voltage; defines safe blocking margin in HV DC or AC line-commutated systems |
| ITAVM @ TC=85°C | 2300 A - continuous RMS current handling under forced two-sided cooling; sets base thermal design envelope |
| ITSM (10 ms) | 93000 A - short-circuit surge current rating; determines crowbar fault-clearing capability |
| (diT/dt)cr | 5000 A/µs - minimum required rate of rise for reliable turn-on without false triggering |
| RthJC | 4.5 K/kW - junction-to-case thermal resistance under two-sided cooling; used to calculate max junction temp rise |
| PLM max | 40 mW - maximum gate trigger light power; defines optical driver output requirement |
| vT0 / rT | 1.2 V / 0.35 mΩ - threshold voltage and slope resistance; define conduction loss model vT = vT0 + iT × rT |
Pinout & Package
Package: Press-pack, double-sided cooled, 172.5 mm diameter, 40 mm height, with anode (terminal 1), cathode (terminal 2), and optical gate input (terminal 4.1). Requires mechanical clamping force of 90–130 kN for reliable thermal and electrical contact.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current entry point during conduction | High-current terminal; must be mounted to heatsink with uniform pressure and thermal interface material |
| Cathode (2) | Main current exit point during conduction | Second high-current terminal; forms closed conduction path with anode under optical gate control |
| Optical Gate (4.1) | Light-trigger input interface | Accepts fiber-coupled or LED-driven optical pulse; no electrical gate connection required |
Key Features
| Feature | Design Value |
|---|---|
| Integrated break-over diode | Enables self-protective overvoltage turn-on without external snubber or crowbar controller |
| Two-sided cooling interface | Supports 4.5 K/kW thermal resistance only when both anode and cathode surfaces are actively cooled |
| 5000 A/µs di/dt immunity | Permits direct series connection in high-di/dt pulsed power stacks without dynamic voltage sharing networks |
| 40 mW optical trigger power | Compatible with standard IEC 61000-4-5 compliant optocouplers and fiber-optic gate drivers |
Applications
| Crowbar Protection Systems | Pulsed Power Supplies |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar light-triggered thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1200N14KOF | 1400 V VRRM, 1200 A ITAVM, same press-pack package but lower voltage/current rating | Suitable for 10–15 kV systems with lower energy demands; not rated for 8000 V blocking | Select when system voltage < 15 kV and surge current < 50 kA; reduces cost and footprint |
| T1730N80TOF | 8000 V VRRM, 3000 A ITAVM, higher current rating, identical optical trigger interface | Requires higher clamping force (110–150 kN); better suited for continuous-duty pulsed loads > 3 kA RMS | Select when ITAVM > 2500 A is required and thermal management supports increased RthJC sensitivity |
Compared with TT1200N14KOF and T1730N80TOF, T2563NH80TOHXOSA1 offers optimal balance of 8000 V blocking, 2300 A average current, and 93 kA surge capacity-making it ideal for crowbar systems where voltage margin and single-pulse robustness are prioritized over continuous RMS current.

FAQ
What is the required optical trigger signal for T2563NH80TOHXOSA1?
The device requires a minimum gate trigger light power of 40 mW at 25°C, delivered via fiber-optic coupling or high-intensity LED. Pulse width must exceed 5 µs to ensure reliable latching, and the optical source must comply with IEC 61000-4-5 for surge immunity in industrial environments.
Can T2563NH80TOHXOSA1 be used with single-sided cooling?
No-this thyristor is specified for two-sided cooling only. Single-sided mounting increases RthJC to 8.2 K/kW (anode-side) or 10.0 K/kW (cathode-side), exceeding thermal design limits at rated current. Mechanical clamping must engage both terminals uniformly to maintain electrical integrity and thermal performance.
What is the maximum allowable junction temperature and how is it monitored?
The absolute maximum junction temperature (Tvj max) is 120°C. Since the device lacks integrated temperature sensors, junction temperature must be inferred indirectly using case temperature measurements (TC), thermal resistance data (RthJC = 4.5 K/kW), and measured power dissipation (P = vT × iT). Derating applies above 85°C case temperature.
Does T2563NH80TOHXOSA1 require a snubber circuit?
A snubber is not required for normal operation due to its integrated break-over diode and 2000 V/µs (dvD/dt)cr rating. However, a small RC snubber may be added in highly inductive circuits where commutation dv/dt exceeds 1500 V/µs to reduce stress on the internal protection structure during forced turn-off events.
