Product details
Overview
T880N14TOFXPSA1 from Infineon Technologies is a high-power, phase-control thyristor designed for industrial AC power regulation in medium- to high-voltage line-commutated converters. It delivers 880 A average on-state current at TC = 85 °C, 1400 V repetitive peak off-state voltage (VDRM/VRRM), and 17.5 kA non-repetitive surge current (ITSM) with 250 µs circuit commutated turn-off time (tq), enabling robust operation in HVDC converter valves and traction rectifiers.
For engineers reviewing the T880N14TOFXPSA1 datasheet, T880N14TOFXPSA1 pinout, T880N14TOFXPSA1 application, or T880N14TOFXPSA1 equivalent, key selection criteria include validated gate trigger current (IGT ≤ 250 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.032 °C/W two-sided cooling), and pressure-contact Si-pellet construction for high-current reliability under forced-air or liquid-cooled busbar mounting.
Technical Context
This thyristor operates as a line-commutated, gate-controlled rectifier in phase-angle controlled AC–DC conversion systems. Its design centers on high di/dt capability (200 A/µs) and high dv/dt immunity (1000 V/µs), ensuring reliable turn-on under high dv/dt transients and stable blocking during commutation recovery.
The device uses a silicon pellet with double-sided pressure contact and requires precise clamping force (10.5–21 kN) to maintain low thermal resistance (RthJC = 0.032 °C/W) and uniform current distribution. Its 125 °C maximum junction temperature and -40 °C to +125 °C operating range support continuous-duty industrial environments with transient overloads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1400 V - Repetitive peak forward/reverse blocking voltage; defines maximum AC line voltage it can control without conduction. |
| ITAVM (TC = 85 °C) | 880 A - Maximum average on-state current under continuous sinusoidal conduction with two-sided heatsink cooling. |
| ITSM (tP = 10 ms) | 17500 A - Non-repetitive surge current handling; supports short-circuit withstand in motor drives and rectifier fault conditions. |
| tq (turn-off time) | 250 µs - Circuit commutated turn-off delay; determines minimum commutation interval in 50/60 Hz phase-controlled inverters. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; ensures immunity to false triggering from fast transients in high-dv/dt grid interfaces. |
| RthJC (two-sided) | 0.032 °C/W - Junction-to-case thermal resistance; enables efficient heat extraction via dual-surface copper busbar mounting. |
| IGT (max) | 250 mA - Maximum gate trigger current required at 25 °C and 12 V anode voltage; sets driver output capability requirement. |
Pinout & Package
Package: TO-200AB (also designated "TO-200AB" or "Press-Pack") - Double-sided cooled, pressure-contact thyristor housed in a ceramic-metal insulated module with flat gate and auxiliary cathode terminals. Requires mechanical clamping (10.5–21 kN) for electrical and thermal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current terminal (positive conduction path) | High-current DC output node in rectifier arms; must be bolted to heatsink with specified clamping force. |
| Cathode (2) | Main current terminal (negative conduction path) | Primary return path for on-state current; electrically isolated from heatsink in standard mounting. |
| Gate (4) | Control input for turn-on initiation | Flat-pin gate terminal requiring ≤250 mA trigger pulse; sensitive to dv/dt-induced false firing if unshielded. |
| Auxiliary Cathode (5) | Secondary cathode connection for gate drive reference | Provides low-inductance gate return path; improves triggering reliability in high-di/dt applications. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1600N14KOF | Higher ITAVM (1600 A at TC = 85 °C); identical VDRM (1400 V); larger TO-200AB package with higher clamping force (25 kN). | Targeted at higher-current valve stacks (≥2000 A per arm); not drop-in due to mechanical footprint and mounting force mismatch. | Select when system-level current rating exceeds 1200 A average and thermal design accommodates larger clamping interface. |
| T920N14TOF | Lower ITAVM (920 A at TC = 85 °C); same VDRM (1400 V); identical TO-200AB package but rated for lower ITSM (15.5 kA). | Suitable for lower-duty-cycle applications (e.g., SVC TCRs with <10% duty factor); reduced surge margin limits fault tolerance in HVDC. | Choose for cost-sensitive, non-critical rectification where 15.5 kA ITSM suffices and thermal headroom is available. |
Compared with TT1600N14KOF and T920N14TOF, T880N14TOFXPSA1 offers optimal balance of 880 A continuous rating, 17.5 kA surge capacity, and standardized TO-200AB mechanical interface-making it the preferred choice for 1 MW–5 MW industrial rectifier systems requiring proven field reliability and supply continuity.

FAQ
What is the recommended clamping force for T880N14TOFXPSA1?
The datasheet specifies a clamping force range of 10.5–21 kN for reliable thermal and electrical contact. Below 10.5 kN, RthJC degrades significantly and risk of hot-spotting increases; above 21 kN may damage ceramic insulators or deform metal housings. Use calibrated torque tools and follow Infineon's mounting sequence in Application Note AN2008-001.
Can T880N14TOFXPSA1 be used in parallel configurations?
Yes-its double-sided pressure contact and matched on-state voltage (vT ≤ 1.17 V at 1 kA) enable current sharing in parallel strings. However, external gate drive balancing (matched RGK resistors and low-inductance layout) and identical heatsink mounting are mandatory. Derate total string current by 15% for thermal mismatch.
What gate drive voltage and current are required for reliable turn-on?
A minimum gate pulse of 12 V with ≥250 mA peak current (at 25 °C) ensures turn-on across the full temperature range. For robustness at -40 °C, apply 15 V/350 mA pulses ≥20 µs wide. Avoid continuous gate voltage >5 V to prevent gate degradation per DIN IEC 60747-6.
Does T880N14TOFXPSA1 have a built-in snubber or protection circuitry?
No-it is a bare die thyristor with no integrated snubbers, TVS, or protection logic. External RC snubbers (designed per vT and di/dt ratings) and fast-acting fuses (rated ≤15 kA I²t) are mandatory for safe operation in inductive loads or high-dv/dt environments.
