Product details
Overview
T830N12TOFXPSA1 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 1200 V repetitive peak off-state voltage (VDRM/VRRM), 1920 A RMS on-state current (ITRMS), and 14.5 kA non-repetitive surge current (ITSM) at 10 ms, enabling robust operation in 3-phase rectifiers and motor drives operating up to 690 V AC mains.
For engineers reviewing the T830N12TOFXPSA1 datasheet, T830N12TOFXPSA1 pinout, T830N12TOFXPSA1 application, or T830N12TOFXPSA1 equivalent, key selection criteria include gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.030 °C/W two-sided), and latching current (1500 mA) under standard 12 V anode-cathode bias.
Technical Context
This thyristor employs a planar, pressure-contact silicon pellet structure with dual-side cooling capability and is optimized for forced-commutated and line-commutated applications requiring precise phase-angle control. Its 250 µs typical turn-off time (tq) and 120 A/µs critical di/dt rating support reliable commutation in high-inductance DC link circuits.
The device features a defined on-state characteristic (vT = A + B·iT + C·ln(iT) + D·iT²) with slope resistance of 0.35 mΩ and threshold voltage of 0.85 V at maximum junction temperature, enabling accurate conduction loss modeling across 200–4100 A load ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1200 V - Maximum repetitive blocking voltage in both directions, defining compatibility with 690 V AC three-phase systems. |
| ITRMS | 1920 A - Continuous RMS current handling capacity under sinusoidal 180° conduction with two-sided heatsink cooling. |
| ITAVM @ TC=85°C | 844 A - Average on-state current limit at 85 °C case temperature, used for thermal derating in steady-state designs. |
| ITSM (10 ms) | 14500 A - Short-circuit withstand capability, critical for fault ride-through in industrial motor starters. |
| (dv/dt)cr | 1000 V/µs - Minimum required snubber dv/dt immunity to prevent false triggering during voltage transients. |
| RthJC (two-sided) | 0.030 °C/W - Junction-to-case thermal resistance enabling ≤125 °C junction operation at 844 A average current with 70 °C heatsink. |
| IGT max | 250 mA - Maximum gate trigger current needed at 25 °C, informing driver stage sizing and isolation requirements. |
Pinout & Package
Package: TO-264 (isolated mounting base), metal-can, pressure-contact construction with clamping force 9–18 kN. Anode and cathode terminals are flat copper surfaces; gate is a flat or round terminal per AMP 60598 spec.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current entry point during forward conduction | High-current copper surface rated for 1920 A RMS; requires torque-controlled mounting and thermal interface material. |
| Cathode (2) | Main current exit point during forward conduction | Electrically isolated copper surface; serves as reference for gate drive and thermal path in dual-sided cooling. |
| Gate (4) | Control electrode initiating conduction | Low-energy trigger input (≤250 mA, ≤1.5 V); must be driven with fast rise time to ensure reliable turn-on at high dv/dt. |
| Auxiliary Cathode (5) | Secondary cathode connection for enhanced gate sensitivity | Improves latching behavior and reduces required IGT under marginal conditions; tied internally to main cathode in most layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Two-sided thermal interface | 0.030 °C/W RthJC enables 30% higher ITAV vs. single-sided cooling at same case temperature. |
| High dv/dt immunity | 1000 V/µs critical rate prevents spurious turn-on in noisy industrial environments without oversized snubbers. |
| Defined on-state V–I model | Four-term analytical equation (A=1.173, B=1.489E−4, C=−9.456E−2, D=1.966E−2) supports precise loss simulation in SPICE and thermal tools. |
| Line-commutated turn-off optimization | 250 µs typical tq at 100 V reverse recovery voltage ensures reliable extinction in 50/60 Hz phase-controlled rectifiers. |
| Robust gate non-trigger margin | 0.2 V max VGD at 0.5×VDRM ensures immunity to noise-induced false triggering during high-voltage blocking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1600N12KOF | Higher VDRM (1200 V same), but lower ITAVM (750 A @ 85 °C) and higher RthJC (0.035 °C/W). | Less suitable for continuous 800+ A loads; requires larger heatsink volume for same thermal margin. | Select when gate drive energy budget is constrained-lower IGT (150 mA max) eases driver design. |
| T1330N12TOF | Same VDRM and ITAVM, but 10% lower ITSM (13.2 kA) and no auxiliary cathode terminal. | Lacks auxiliary cathode for improved latching margin in low-temperature or high-dv/dt environments. | Prefer where board space is limited-identical footprint but simplified 3-terminal layout (no Aux-K). |
Compared with TT1600N12KOF and T1330N12TOF, the T830N12TOFXPSA1 offers superior thermal performance (0.030 °C/W), higher surge rating (14.5 kA), and auxiliary cathode support-making it optimal for high-reliability, high-current line-commutated systems where thermal headroom and turn-on robustness are critical.

FAQ
What is the recommended gate drive circuit for T830N12TOFXPSA1?
A pulse transformer or optocoupler-isolated gate driver delivering ≥1 A peak gate current with <1 µs rise time is recommended. The gate must be triggered with minimum 10 V amplitude and 20 µs pulse width to ensure latching at full temperature range. Auxiliary cathode connection improves margin but is optional in standard layouts.
Can T830N12TOFXPSA1 be used in forced-commutated (GTO-like) circuits?
No-it is a conventional phase-control thyristor without gate-turn-off capability. Turn-off relies solely on natural current zero-crossing or external commutation circuits. Its 250 µs tq is specified only for line-commutated conditions with 100 V reverse voltage and 10 A/µs di/dt.
What mechanical mounting torque is required for reliable thermal contact?
Clamping force must be maintained between 9 kN and 18 kN, corresponding to 25–35 N·m torque on M12 mounting bolts with lubricated threads and hardened washers. Under-torque increases RthJC by >20%; over-torque risks silicon fracture or housing deformation.
Is the auxiliary cathode terminal electrically isolated from the main cathode?
No-the auxiliary cathode is internally bonded to the main cathode and shares the same potential. Its purpose is to provide localized low-impedance gate return path near the silicon edge, improving turn-on uniformity and reducing required IGT under high dv/dt stress.
