Product details
Overview
T1590N26TOFVTXPSA1 from Semikron is a high-power, phase-control thyristor designed for industrial AC power regulation in medium- to high-voltage line-commutated converters. It delivers 1590 A average on-state current at 85 °C case temperature, supports 2600 V repetitive peak off-state voltage (VDRM/VRRM), and withstands 32 kA non-repetitive surge current (ITSM) - enabling use in 3-phase rectifiers, motor soft-starters, and static VAR compensators operating up to 690 V AC mains.
For engineers reviewing the T1590N26TOFVTXPSA1 datasheet, T1590N26TOFVTXPSA1 pinout, T1590N26TOFVTXPSA1 application, or T1590N26TOFVTXPSA1 equivalent, key selection criteria include verified gate trigger current (≤300 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.0125 °C/W, two-sided cooling), and validated 400 µs turn-off time under rated commutation conditions.
Technical Context
This thyristor operates as a line-commutated, gate-controlled switch in phase-angle controlled AC systems. Its 2600 V VDRM/VRRM rating targets 415–690 V AC industrial networks with safety margin, while its 150 A/µs diT/dt capability ensures reliable turn-on under high-current inductive loads. The device requires precise gate pulse timing (≤3 µs delay) and sustains conduction only when forward-biased and triggered - no self-commutation capability.
Thermal design relies on two-sided forced cooling: junction-to-case resistance is 0.0125 °C/W (max), and case-to-heatsink resistance drops to 0.003 °C/W with dual-side mounting. Its 125 °C maximum junction temperature and -40 °C to +125 °C operating range support deployment in harsh industrial enclosures with ambient temperatures up to 70 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2600 V - Maximum repetitive blocking voltage in both directions; enables direct use in 690 V AC three-phase systems with 2× safety margin. |
| ITAVM (TC = 85 °C) | 1590 A - Continuous average on-state current at 85 °C case temperature; defines steady-state power handling under sinusoidal 180° conduction. |
| ITRM | 3600 A - RMS on-state current; determines thermal stress under real-world load profiles including harmonic content. |
| ITSM (10 ms) | 32000 A - Non-repetitive surge current capacity; supports short-circuit ride-through in motor drives and welder primary circuits. |
| (dvD/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage; prevents false triggering during fast transients in transformer-coupled or long-cable applications. |
| tq (typ.) | 400 µs - Typical circuit-commutated turn-off time at Tvj max; sets minimum commutation interval for line-frequency phase control. |
| RthJC (two-sided) | 0.0125 °C/W - Junction-to-case thermal resistance; mandates high-pressure dual-face heatsinking for thermal management. |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mount thyristor with isolated anode/cathode terminals and flat gate contact. Requires clamping force of 30–65 kN and provides 25 mm creepage distance per IEC 60664.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current entry terminal | Carries full load current into device; electrically isolated from heatsink; must be mounted with conductive thermal interface on one side of heatsink stack. |
| Cathode (2) | Main current exit terminal | Completes main conduction path; also isolated; mounted on opposite side of heatsink stack for two-sided cooling. |
| Gate (4) | Control input terminal | Flat metal contact requiring low-inductance gate drive; triggers conduction when ≥300 mA pulse applied at ≤3 V with diG/dt ≥1.6 A/µs. |
| Auxiliary Cathode (5) | Secondary cathode reference | Provides stable gate-cathode reference point independent of main cathode voltage drop; improves trigger reliability under high di/dt conditions. |
Key Features
| Feature | Design Value |
|---|---|
| High diT/dt capability | 150 A/µs - Enables robust turn-on into highly inductive loads (e.g., transformer primaries) without commutation failure. |
| Low on-state voltage | 1.38 V at 1 kA (Tvj max) - Reduces conduction losses by ~15% vs. comparable 2200 V thyristors, improving system efficiency in high-current rectifiers. |
| Two-sided thermal path | 0.0125 °C/W RthJC - Allows symmetric heat extraction from both anode and cathode faces, doubling effective thermal interface area vs. single-sided packages. |
| Gate non-trigger immunity | VGD ≤ 0.25 V at 0.5 VDRM - Prevents false triggering during high dv/dt transients across main terminals, enhancing noise immunity in EMI-prone environments. |
| Validated commutation performance | tq = 400 µs at 100 V reverse recovery - Confirmed turn-off behavior under standardized line-commutated conditions per IEC 60747-6. |
Applications
| Industrial Motor Soft-Starters | Medium-Voltage Rectifier Bridges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1590N26KOF | Same VDRM/VRRM (2600 V) and ITAVM (1590 A), but uses KOOLPAK™ ceramic package with integrated heatsink interface; RthJC = 0.0135 °C/W (anode-side only). | Designed for single-sided forced-air cooling; lacks auxiliary cathode terminal; unsuitable for ultra-low-noise gate referencing. | Select when space-constrained PCB-mount integration is required and gate noise immunity is secondary to thermal footprint. |
| ST1590N26TOF | Identical electrical specs but rated for 130 °C max junction temperature; RthJC = 0.0117 °C/W (two-sided); gate trigger current reduced to 250 mA max. | Approved for extended-temperature industrial environments (e.g., oil & gas downhole controls); higher thermal margin allows derating for longer lifetime. | Select when operating ambient exceeds 70 °C or when 10-year field reliability under thermal cycling is mandatory. |
Compared with TT1590N26KOF and ST1590N26TOF, the T1590N26TOFVTXPSA1 offers superior gate noise immunity via auxiliary cathode, stricter 125 °C junction limit for predictable aging, and validated 400 µs tq under standard IEC commutation - making it optimal for precision phase control in EMI-sensitive SVC and soft-starter systems.

FAQ
What is the recommended gate drive circuit for T1590N26TOFVTXPSA1?
A low-inductance, pulse-type gate driver delivering ≥1.6 A peak current with diG/dt ≥1.6 A/µs and ≤3 µs delay is required. Use twisted-pair or coaxial gate wiring, minimize loop area, and apply a negative bias (-2 V) during off-state to suppress dv/dt-induced false triggering. Gate resistor must be selected to limit peak power to ≤60 W for 0.5 ms pulses per IEC 60747-6.
Can T1590N26TOFVTXPSA1 be used in forced-commutated (self-commutated) circuits?
No - this is a line-commutated thyristor without integrated turn-off capability. It relies on external circuit reversal of anode-cathode voltage (e.g., via commutation chokes or auxiliary SCRs) to achieve turn-off. Attempting gate-controlled turn-off will result in device destruction due to secondary breakdown.
What is the significance of the auxiliary cathode (terminal 5) on this device?
The auxiliary cathode provides a dedicated, low-impedance reference point for the gate circuit, decoupling gate triggering from main cathode voltage transients during high di/dt conduction. This improves trigger reliability and reduces required gate drive power compared to standard two-terminal thyristors in noisy, high-power environments.
How does two-sided cooling affect thermal design for this thyristor?
Two-sided cooling halves the effective thermal resistance path: heat flows simultaneously from junction to anode face and junction to cathode face. This requires symmetrical mounting pressure (30–65 kN), matched thermal interface materials on both sides, and heatsinks capable of dissipating >100 kW/m². Failure to cool both sides degrades RthJC to 0.025 °C/W and risks thermal runaway.
