Product details

Overview

T3160N18TOFVTXPSA1 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 3160 A average on-state current at 85 °C case temperature, 1800 V repetitive peak off-state voltage (V_DRM/V_RRM), and 63 kA non-repetitive surge current (t_P = 10 ms) - enabling robust operation in 3.3 kV-class grid-connected converters.

For engineers reviewing the T3160N18TOFVTXPSA1 datasheet, T3160N18TOFVTXPSA1 pinout, T3160N18TOFVTXPSA1 application, or T3160N18TOFVTXPSA1 equivalent, key selection criteria include verified gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.0085 °C/W, two-sided cooling), and latching current (1500 mA) under standardized test conditions per IEC 60747-6.

Technical Context

This thyristor operates as a line-commutated, gate-controlled rectifier in phase-angle controlled AC–DC conversion circuits. Its design supports bidirectional blocking (1800 V V_DRM/V_RRM) and handles RMS on-state current up to 7250 A with a slope resistance of 0.082 mΩ at maximum junction temperature.

It features a silicon pellet with pressure-contact construction, requiring precise clamping force (42–95 kN) and two-sided heatsinking to maintain junction temperature ≤125 °C. The device exhibits 250 µs typical commutated turn-off time (t_q) under defined recovery conditions (v_RM = 100 V, dv_D/dt = 20 V/µs).

Equivalent & Alternatives

The following parts are listed as comparable options for similar phase-control thyristor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TT1700N18KOF	Lower I_TAVM (1700 A @ 85 °C); same V_DRM/V_RRM (1800 V); higher R_thJC (0.0152 °C/W, anode-side cooled)	Targeted at lower-current SVC modules where single-sided cooling suffices	Select when system-level thermal design uses anode-only heatsinking and average current ≤1700 A
T3230N18TOFVTXPSA1	Higher I_TAVM (3230 A @ 85 °C); identical package, pinout, and thermal specs	Suitable for upgraded motor drive stacks requiring +2.2% current margin without layout change	Choose for drop-in reliability enhancement where existing PCB footprint and clamping must be retained

Compared with TT1700N18KOF, T3160N18TOFVTXPSA1 provides 86% higher average current capacity and 44% lower junction-to-case thermal resistance under two-sided cooling - directly enabling higher power density in space-constrained converter cabinets.

FAQ

What is the minimum gate trigger voltage required for reliable turn-on?

The maximum gate trigger voltage (V_GT) is specified as 2.5 V at 25 °C and v_D = 12 V. Reliable turn-on is achieved with ≥3.0 V gate pulses under worst-case conditions (T_vj = 125 °C), ensuring margin against aging and contact resistance drift in press-pack assemblies.

Can this thyristor be used in forced-commutated circuits?

No - T3160N18TOFVTXPSA1 is a line-commutated thyristor with no inherent turn-off capability. Its 250 µs t_q applies only to natural commutation via AC current zero-crossing. Forced commutation requires GTOs or IGCTs, not standard phase-control thyristors.

What clamping force range ensures optimal thermal and electrical contact?

The datasheet specifies a clamping force range of 42–95 kN. Below 42 kN, contact resistance rises, increasing v_T and localized heating; above 95 kN risks ceramic insulator fracture. Use calibrated hydraulic tools and follow Infineon's torque-to-force conversion tables for the TO-247-compatible stud mount.

Is auxiliary cathode (terminal 5) mandatory for operation?

Terminal 5 is not mandatory for basic conduction but improves gate control margin under high di/dt conditions (≥100 A/µs). It reduces gate-cathode loop inductance and stabilizes triggering in paralleled stacks - recommended for >5 kA systems per IEC 61800-4.
