Product details
Overview
T1590N28TOFVTXPSA1 from Infineon Technologies is a high-power phase-control thyristor designed for industrial AC power regulation in medium-voltage motor drives, static VAR compensators, and DC traction rectifiers. It delivers 1590 A average on-state current at 85 °C case temperature, 2800 V repetitive peak off-state voltage (VDRM/VRRM), and supports 32 kA non-repetitive surge current with 5.12×10⁶ A²s I²t rating.
For engineers reviewing the T1590N28TOFVTXPSA1 datasheet, T1590N28TOFVTXPSA1 pinout, T1590N28TOFVTXPSA1 application, or T1590N28TOFVTXPSA1 equivalent, key selection criteria include gate trigger current (≤300 mA), critical dv/dt capability (1000 V/µs), junction-to-case thermal resistance (0.0125 °C/W two-sided cooling), and 400 µs commutated turn-off time under rated conditions.
Technical Context
This thyristor operates as a line-commutated, gate-controlled rectifier in phase-angle controlled AC–DC conversion circuits. Its 125 °C maximum junction temperature, 1500 mA latching current, and 300 mA holding current ensure reliable turn-on and conduction stability under high-current transient loads.
The device features a pressure-contact silicon pellet construction with dual-sided heat sinking capability, enabling 3600 A RMS on-state current handling. Its 150 A/µs critical di/dt rating and 1000 V/µs critical dv/dt rating support robust operation in high-di/dt inductive load switching and noisy grid environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1590N28KOF | Same VDRM/VRRM (2800 V), but TO-280AB package with single-sided cooling only; RthJC = 0.0232 °C/W (anode-cooled). | Limited to lower RMS current (2290 A @ TC=55 °C) and higher thermal resistance; unsuitable for dual-sided heatsink layouts. | Select when space constraints prevent dual-sided mounting or when lower-cost single-sided cooling suffices. |
| T1630N28TOF | Higher ITAVM (1630 A @ 85 °C); identical TO-280AA package and thermal specs; 10% higher gate trigger current (330 mA max). | Marginally higher current capacity; same footprint and cooling requirements; compatible in most legacy designs with minor gate drive adjustment. | Choose for new designs needing extended current headroom without changing mechanical layout or thermal system. |
Compared with TT1590N28KOF, T1590N28TOFVTXPSA1 delivers 2.7× lower thermal resistance and 57% higher RMS current, while T1630N28TOF offers incremental current uplift with identical packaging-making the original optimal for thermally constrained, dual-cooled high-RMS applications.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +125 °C, as specified in the datasheet's operating temperature range (Tc op: –40 °C to +125 °C). At this temperature, the device sustains 1590 A average on-state current with two-sided cooling and sinusoidal conduction at 180°. Exceeding this limit risks irreversible junction degradation and premature failure.
Does T1590N28TOFVTXPSA1 require a heatsink, and what mounting force is needed?
Yes, mandatory two-sided heatsinking is required due to its 3600 A RMS rating and 0.0125 °C/W RthJC. The datasheet specifies a clamping force of 30–65 kN applied across the anode and cathode surfaces to maintain low thermal resistance and mechanical integrity. Insufficient force increases contact resistance and causes localized overheating.
Can this thyristor be used in forced-commutated (GTO-like) circuits?
No-it is a conventional phase-control thyristor with no gate turn-off capability. Its 400 µs circuit commutated turn-off time (tq) assumes natural current zero-crossing for commutation. Attempting forced commutation will result in destructive failure, as it lacks integrated GTO structure or integrated reverse-conducting capability.
What gate drive parameters are required for reliable turn-on?
A minimum gate trigger current of 1.6 A (with di/dt ≥1.6 A/µs) and pulse width ≥20 µs is recommended for guaranteed turn-on under worst-case conditions. The absolute maximum ratings specify ≤300 mA IGT and ≤3 V VGT at 25 °C, but practical designs use higher energy pulses to ensure robust triggering across temperature and aging.
