Product details
Overview
T600N95TOFXPSA1 from Infineon Technologies is a high-power phase-control thyristor designed for medium-voltage AC line commutated switching in industrial drive rectifiers and soft starters. It delivers 590 A average on-state current at TC = 85°C, 9500 V repetitive peak off-state voltage (VDRM/VRRM), and withstands 12.8 kA surge current (ITSM) with 1.254 V threshold voltage (vT0) and 1.414 mΩ slope resistance (rT).
For engineers reviewing the T600N95TOFXPSA1 datasheet, T600N95TOFXPSA1 pinout, T600N95TOFXPSA1 application, or T600N95TOFXPSA1 equivalent, key selection criteria include blocking capability at 50/60 Hz over –40°C to +125°C, clamping force requirements (15–24 kN), two-sided cooling thermal interface, and gate trigger sensitivity (IGT ≤ 350 mA at 12 V).
Technical Context
This thyristor operates as a line-commutated, gate-controlled semiconductor switch in high-power AC-to-DC conversion. Its design supports forced commutation-free operation in 50/60 Hz systems, with critical di/dt rating of 100 A/µs and dv/dt rating of 2000 V/µs - enabling reliable turn-on under high inductive load conditions without spurious triggering.
Thermal performance is defined by a maximum junction temperature of 125°C and a case-to-junction thermal resistance of 19.0 K/kW under two-sided DC cooling. The device uses silicon pellet with pressure-contact packaging, requiring precise mechanical clamping (15–24 kN) across 50 mm contact diameter to maintain low RthJC and stable vT characteristics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 9500 V - ensures full 50/60 Hz blocking up to medium-voltage grid levels (e.g., 6.6 kV AC systems with safety margin) |
| ITAVM (TC = 85°C) | 590 A - defines continuous DC output current capability in rectifier bridges with active heatsink management |
| ITSM (10 ms) | 12800 A - supports short-circuit ride-through in motor drive front-ends without destructive failure |
| vT0 / rT | 1.254 V / 1.414 mΩ - determines conduction loss profile: ~1.9 V drop at 1000 A, critical for thermal design of parallel modules |
| (diT/dt)cr | 100 A/µs - sets minimum gate drive di/dt requirement to ensure robust turn-on under high dI/dt loads |
| RthJC (two-sided) | 19.0 K/kW - establishes thermal path efficiency; requires ≥15 kN clamping force to achieve specified value |
| Qr (recovered charge) | 10 mAs - influences snubber sizing and commutation circuit losses in phase-controlled rectifier topologies |
Pinout & Package
Package: Pressure-contact, disc-type thyristor with two-sided cooling interface. Diameter: 75 mm; contact diameter: 50 mm; height: 26 mm; clamping force range: 15–24 kN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (flat surface) | Main current terminal (high-side) | Carries full load current; must be mounted to heatsink with uniform pressure; polarity-sensitive in bridge configuration |
| Cathode (flat surface) | Main current terminal (low-side) | Completes main conduction path; electrically isolated from gate; shares thermal path with anode via case |
| Gate (flat tab, 2.8×0.5 mm) | Control input | Triggers conduction when ≥350 mA pulse applied at ≤2.5 V; sensitive to noise due to high dv/dt immunity requirement |
| Hilfskathode (auxiliary cathode) | Gate reference node | Provides low-inductance return path for gate drive; required for stable triggering under high di/dt conditions |
Key Features
| Feature | Design Value |
|---|---|
| Full 50/60 Hz blocking | Maintains VDRM/VRRM integrity across –40°C to +125°C ambient, eliminating derating in outdoor or uncontrolled environments |
| High surge current capability | Withstands 12.8 kA for 10 ms without latch-up or junction damage - enables use in unfused industrial mains interfaces |
| Two-sided thermal interface | 19.0 K/kW RthJC achieved only with symmetric clamping and dual heatsink contact - reduces hotspot risk in high-power stacks |
| Low vT0 + rT combination | 1.254 V threshold + 1.414 mΩ slope yields <2.0 V conduction drop at 800 A - directly lowers rectifier bridge power loss and cooling cost |
| Controlled Qr & tq | 10 mAs recovered charge and 900 µs turn-off time enable predictable snubber design for line-commutated inverters and cycloconverters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1200N10KOF | 10000 V VDRM/VRRM, 600 A ITAVM, 13.5 kA ITSM, RthJC = 18.5 K/kW (two-sided) | Slightly higher voltage rating and surge capacity; identical package footprint and clamping specs | Preferred where system overvoltage margin exceeds 5% or fault current >12.8 kA is expected |

FAQ
What is the recommended clamping force range for T600N95TOFXPSA1?
The device requires a mechanical clamping force between 15 kN and 24 kN to ensure proper thermal contact and low RthJC. Deviation below 15 kN increases junction temperature rise and risks premature thermal runaway; exceeding 24 kN may deform the pressure-contact structure or damage internal silicon bonding.
Can T600N95TOFXPSA1 be used in single-sided cooled configurations?
Yes, but with significant derating: RthJC rises to 20.5 K/kW for anode-side-only cooling and is unspecified for cathode-side-only. Two-sided cooling is mandatory to achieve the rated 590 A ITAVM and 19.0 K/kW thermal resistance - single-sided use requires recalculating current limits using transient thermal impedance curves from page 5.
What gate drive parameters ensure reliable triggering?
A minimum gate current pulse of 350 mA at ≤2.5 V for ≥20 µs is required, with diG/dt ≥6 A/µs. The auxiliary cathode (Hilfskathode) must be connected to gate return to minimize inductance; failure to do so increases tgd and risks misfiring under high dv/dt conditions.
How does Qr affect snubber design in phase-controlled rectifiers?
With Qr = 10 mAs and IRM = 270 A, the device demands snubbers sized to absorb 10 mAs × 8000 V ≈ 80 J per commutation event. This directly determines RC time constant and resistor power rating - undersized snubbers cause voltage overshoot exceeding VRRM and lead to catastrophic failure during turn-off.
