Product details
Overview
TD92N12KOFHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 1200 V repetitive peak off-state voltage (VDRM/VRRM), 92 A average on-state current (ITAVM) at TC = 85°C, and 160 A RMS on-state current (ITRMSM). It features a dual-arm press-pack construction with AlN ceramic isolation, designed for industrial AC power control in medium-power rectifier and motor drive systems.
For engineers reviewing the TD92N12KOFHPSA1 datasheet, TD92N12KOFHPSA1 pinout, TD92N12KOFHPSA1 application, or TD92N12KOFHPSA1 equivalent, key selection criteria include its 150 µs circuit-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 thyristor module implements a dual-thyristor, anti-parallel configuration in a single press-pack housing, enabling bidirectional AC phase control without external reverse-blocking components. Its gate trigger current (IGT ≤ 120 mA) and non-trigger voltage (VGD ≤ 0.2 V) support standard pulse transformer or optocoupler-based firing circuits.
The device operates with a threshold voltage (V(TO)) of 0.85 V and slope resistance (rT) of 2.15 mΩ at maximum junction temperature, delivering predictable conduction loss behavior under sinusoidal and rectangular load currents. Its 2.5 kV RMS insulation test voltage ensures safety in grounded-heatsink industrial installations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1200 V - Maximum repetitive blocking voltage in both directions, defining AC line voltage compatibility up to 850 V RMS. |
| ITAVM (TC = 85°C) | 92 A - Continuous average forward current per arm, determining steady-state thermal design for heatsink sizing. |
| ITRMSM | 160 A - RMS on-state current rating, used for I²t-based fuse coordination and transient overload handling. |
| tq (turn-off time) | 150 µs - Minimum commutation time required for forced-commutated inverters or line-commutated converters. |
| (dv/dt)cr | 1000 V/µs - Critical rate-of-rise of off-state voltage before spurious turn-on; dictates snubber design requirements. |
| RthJC (DC, per module) | 0.175 °C/W - Junction-to-case thermal resistance under DC conduction, essential for calculating case temperature rise. |
| Visol (RMS, 1 min) | 2.5 kV - Isolation withstand voltage between main terminals and baseplate, meeting IEC 60747-6 safety requirements. |
Pinout & Package
TD92N12KOFHPSA1 is housed in a press-pack module with isolated copper baseplate and spring-loaded pressure-contact Si pellets. Terminals are arranged as two independent arms (A1/K1 and A2/K2), each supporting anode and cathode connections. Control terminals (G1, K1 and G2, K2) are separate for independent gating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, K1 | Anode/Cathode of Arm 1 | Primary current path for first thyristor arm; rated for full ITAVM and ITRMSM under conduction. |
| A2, K2 | Anode/Cathode of Arm 2 | Second independent thyristor arm; enables anti-parallel operation for AC phase control or full-wave rectification. |
| G1, K1 | Gate/Cathode of Arm 1 | Low-energy gate interface requiring ≤120 mA trigger current; referenced to K1, not common ground. |
| G2, K2 | Gate/Cathode of Arm 2 | Isolated gate drive path for Arm 2; allows independent triggering or synchronized firing with Arm 1. |
Key Features
| Feature | Design Value |
|---|---|
| AlN ceramic isolation | Provides 2.5 kV RMS insulation and low thermal resistance (0.05 °C/W case-to-heatsink) for high-reliability mounting. |
| Pressure-contact Si pellet | Enables repeatable thermal and electrical contact without solder fatigue, supporting >10⁶ thermal cycles in industrial environments. |
| 150 µs tq rating | Supports line-commutated applications up to 400 Hz and enables use in medium-frequency phase-controlled rectifiers. |
| 1000 V/µs (dv/dt)cr | Reduces need for external dv/dt snubbers in 50/60 Hz AC mains applications with inductive loads. |
| 0.85 V threshold voltage | Ensures stable turn-on behavior across temperature range (-40°C to +130°C case), minimizing gate drive variability. |

FAQ
What is the maximum allowable case temperature for continuous operation?
The TD92N12KOFHPSA1 is rated for continuous operation with a maximum case temperature (Tc) of +130°C, matching its maximum junction temperature (Tvj max = 130°C) under zero thermal resistance conditions. At rated ITAVM = 92 A, typical case temperature remains ≤85°C with a properly sized heatsink and thermal interface material.
Does this module require forced gate triggering or can it be driven with simple pulse transformers?
Yes, the module supports standard pulse transformer gate drives: its maximum gate trigger current (IGT) is 120 mA and gate trigger voltage (VGT) is 1.4 V at 25°C, well within the output capability of industry-standard 1:1 or 2:1 pulse transformers with ≥1 W peak power rating and proper gate resistor selection (typically 10–22 Ω).
How does the press-pack construction affect mounting and thermal interface requirements?
The press-pack design requires precise mechanical torque control: 4 Nm ±15% for M1 mechanical fasteners and 4 Nm ±10% for M2 electrical terminals. A thermally conductive, electrically insulating interface (e.g., ceramic-filled silicone grease or mica washer) must be applied uniformly to ensure full AlN-to-heatsink contact and avoid localized hot spots or delamination under thermal cycling.
Can TD92N12KOFHPSA1 be used in a single-phase B2 bridge configuration?
Yes - the dual-arm architecture supports B2 (two-pulse) single-phase bridge operation. With RthCA ≈ 0.30 °C/W under natural cooling, it delivers up to 120 A output current at TA = 40°C ambient, as confirmed by the datasheet's B2 ID vs. RthCA curves on page 8. Gate timing must ensure complementary firing with adequate commutation margin.
