Product details
Overview
TD92N16KOFAHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 160 A RMS on-state current (ITRMSM), and 104 A average on-state current at TC = 76°C. It features dual thyristor arms in a press-pack configuration with AlN ceramic isolation, designed for industrial AC power control in medium-voltage motor drives and DC traction converters.
For engineers reviewing the TD92N16KOFAHPSA1 datasheet, TD92N16KOFAHPSA1 pinout, TD92N16KOFAHPSA1 application, or TD92N16KOFAHPSA1 equivalent, key selection criteria include its 150 µs commutated turn-off time (tq), 1000 V/µs critical dv/dt rating, 150 A/µs critical di/dt capability, and thermal resistance of 0.175 °C/W (junction-to-case per module, DC).
Technical Context
This dual-arm thyristor module operates in forced- or natural-cooled B2 (two-pulse) and B6 (six-pulse) bridge configurations. Its gate trigger current (IGT ≤ 120 mA) and latching current (IL ≤ 620 mA) support reliable firing under high-noise industrial conditions, while the 0.85 V threshold voltage (V(TO)) and 2.15 mΩ slope resistance (rT) define conduction loss behavior at rated current.
The module's transient thermal impedance ZthJC is characterized for sinusoidal and rectangular current waveforms across conduction angles (Θ = 30°–180°), enabling accurate junction temperature prediction in phase-angle controlled rectifiers. Its 2.5 kV RMS insulation test voltage (1 min) and 12.5 mm creepage distance meet IEC 60747-6 requirements for reinforced isolation in 690 V AC systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage in forward and reverse directions, enabling use in 690 V AC line-fed rectifiers with 2.3× safety margin. |
| ITRMSM | 160 A - RMS on-state current rating per module, defining continuous thermal capacity under full-conduction sine-wave load. |
| ITAVM (TC = 76°C) | 104 A - Average on-state current limit at case temperature of 76°C, used for DC or low-duty-cycle applications. |
| tq (turn-off time) | 150 µs - Commutated turn-off time at Tvj max, critical for minimum extinction angle design in B6 rectifiers operating at 50/60 Hz. |
| (dvD/dt)cr | 1000 V/µs - Critical rate-of-rise of off-state voltage, determining snubber requirements to prevent false triggering during voltage transients. |
| RthJC (DC, per module) | 0.175 °C/W - Junction-to-case thermal resistance under DC conduction, used with heatsink RthCH (0.05 °C/W) to calculate maximum allowable case temperature. |
| vT (max @ 300 A) | 1.62 V - Maximum on-state voltage at 300 A and Tvj max, directly determining conduction losses in high-current operation. |
Pinout & Package
TD92N16KOFAHPSA1 is housed in a press-pack module with isolated copper terminals and AlN ceramic baseplate. Mechanical mounting uses M1 screws (4 Nm ±15%) for case-to-heatsink clamping and M2 screws (4 Nm ±10%) for electrical connections. Control terminals conform to DIN 46244 A (2.8 × 0.8 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Main anode of first thyristor arm | Carries full-phase current in B2/B6 top-arm conduction; requires low-inductance busbar connection. |
| Cathode 1 (K1) | Main cathode of first thyristor arm | Shared node with gate 1 return; forms current path during positive half-cycle conduction. |
| Anode 2 (A2) | Main anode of second thyristor arm | Carries complementary-phase current in B6 configuration; electrically isolated from A1 by internal AlN barrier. |
| Cathode 2 (K2) | Main cathode of second thyristor arm | Common cathode node for B2 center-tap topology; thermally coupled but electrically isolated from K1. |
| Gate 1 (G1) | Control terminal for first thyristor | Receives pulse-trigger signal (≤120 mA, ≤1.4 V); requires <0.2 V non-trigger voltage to prevent spurious firing. |
| Gate 2 (G2) | Control terminal for second thyristor | Independent firing input; galvanically isolated from G1 to enable asymmetric phase control in dual-arm operation. |
Key Features
| Feature | Design Value |
|---|---|
| Double-sided cooling interface | AlN-ceramic baseplate enables symmetric heat extraction from both sides, supporting compact stacked heatsink designs in multi-module cabinets. |
| Pressure-contact Si pellet | Eliminates wire bonds and solder layers, improving thermal cycling reliability (>10⁵ cycles) and reducing contact resistance drift over lifetime. |
| High dv/dt immunity | 1000 V/µs critical dv/dt rating allows direct connection to fast-switching IGBT inverters without external snubbers in hybrid converter topologies. |
| Low conduction loss slope | 2.15 mΩ dynamic resistance minimizes voltage drop rise at overload currents, maintaining predictable thermal rise up to 2050 A surge rating. |
| Reinforced isolation | 2.5 kV RMS insulation (1 min) and 12.5 mm creepage distance comply with EN 50178 for 690 V AC mains-connected equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT92N16KOF | Single-arm configuration; identical VDRM (1600 V), ITAVM (104 A), and RthJC (0.175 °C/W), but lacks second thyristor arm. | Requires two modules for B6 bridge vs. one TD92N16KOFAHPSA1; higher footprint and interconnect complexity. | Select TT92N16KOF only when modular redundancy or independent arm control is required. |
| TD132N16KO | Higher RMS rating (200 A), larger package (220 g), and 0.135 °C/W RthJC; otherwise identical voltage and timing specs. | Over-spec'd for 160 A applications; increases heatsink cost and cabinet space without performance benefit. | Choose TD132N16KO only when future-proofing for >160 A RMS load growth is confirmed. |

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies a maximum case temperature (Tc op) of +130°C, but the average on-state current rating (ITAVM) is derated to 104 A only at TC = 76°C. For continuous operation at full 104 A, the heatsink must maintain case temperature ≤76°C. At higher case temperatures, ITAVM decreases linearly per the TC vs. ITAVM curves on page 7 of the datasheet.
Does TD92N16KOFAHPSA1 require forced air cooling?
No-natural cooling is supported per the "Luftselbstkühlung" section (page 4), where 3 modules per KM14 heatsink (50 W rating) are validated. However, forced cooling (e.g., Papst 4650N fan) extends usable current range: at TC = 76°C, natural cooling supports ~70 A ITAVM, while forced cooling achieves the full 104 A rating.
Can this module be used in asymmetrical half-controlled rectifiers?
Yes-its dual independent gate terminals (G1, G2) and electrically isolated arms (A1/K1, A2/K2) allow independent firing control. This enables asymmetrical operation such as half-controlled B6 bridges where SCRs and diodes share arms, provided gate drive circuits respect the 0.2 V non-trigger voltage (VGD) limit under blocking conditions.
What is the recommended gate drive circuit for reliable triggering?
A pulse transformer or optocoupler-based driver delivering ≥0.6 A peak gate current (iGM), ≥1.4 V gate voltage (VGT), and ≥20 µs pulse width (tg) is required. The datasheet specifies diG/dt ≥ 0.6 A/µs and iGM = 0.6 A for guaranteed latching at 620 mA IL; underspecified drivers risk incomplete turn-on and localized hot-spotting.
