Product details
Overview
TD92N1420KOFHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 1400 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 high-reliability AC power control in industrial rectifier and motor drive systems.
For engineers reviewing the TD92N1420KOFHPSA1 datasheet, TD92N1420KOFHPSA1 pinout, TD92N1420KOFHPSA1 application, or TD92N1420KOFHPSA1 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 thyristor module implements a two-arm, anti-parallel configuration optimized for B2 (two-pulse) and B6 (six-pulse) bridge rectification. Its gate trigger parameters-IGT ≤ 120 mA, VGT ≤ 1.4 V, and tgd ≤ 3 µs-enable reliable firing under high-noise industrial conditions with minimal gate drive power.
Thermal performance is defined by transient junction-to-case impedance ZthJC (analytical model provided), with steady-state RthJC = 0.175 °C/W per module under DC conduction. The module supports natural cooling (KM14 heatsink, 3 modules per sink) and forced-air cooling (Papst 4650N), with maximum junction temperature limited to 130°C.

Pinout & Package
TD92N1420KOFHPSA1 is a press-pack thyristor module housed in an insulated metal baseplate package with AlN (aluminum nitride) internal isolation. Mechanical mounting uses M1 screws (4 Nm ±15%), and electrical terminals conform to DIN 46244 A (2.8 × 0.8 mm flat blade). Weight is 160 g; creepage distance is 12.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A1) | Main current terminal - Arm 1 anode | Carries full load current in one direction; must be bolted to heatsink with specified torque (4 Nm) for thermal and electrical integrity. |
| Cathode (K1) | Main current terminal - Arm 1 cathode | Completes current path for Arm 1; electrically isolated from baseplate via AlN ceramic; requires insulated mounting hardware. |
| Anode (A2) | Main current terminal - Arm 2 anode | Second arm anode for anti-parallel configuration; enables bidirectional AC switching in phase-control bridges. |
| Cathode (K2) | Main current terminal - Arm 2 cathode | Second arm cathode; paired with A2 to form second thyristor arm; shares same thermal interface as K1. |
| Gate (G1) | Control input - Arm 1 gate | Low-energy trigger input (≤120 mA, ≤1.4 V); requires isolated gate driver due to floating potential relative to heatsink. |
| Gate (G2) | Control input - Arm 2 gate | Independent gate for Arm 2; enables independent firing control in asymmetrical or sequential phase-control topologies. |
| Baseplate | Thermal & mechanical interface | Electrically isolated but thermally conductive surface; serves as common heatsink interface for both arms; rated for 3.0 kV insulation test (1 sec). |

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 |
|---|---|---|---|
| TT92N14KOFHPSA1 | Single-arm configuration (vs. dual-arm TD92N); identical VDRM (1400 V), ITAVM (92 A), and RthJC (0.175 °C/W), but lacks anti-parallel integration. | Requires external pairing for AC switching; increases PCB footprint and gate drive complexity in B6 rectifiers. | Select TT92N14KOFHPSA1 only when discrete arm control or modular redundancy is required; otherwise TD92N1420KOFHPSA1 reduces system count and interconnect loss. |
| DT92N14KOFHPSA1 | Same dual-arm layout, but rated for 1600 V VDRM/VRRM and 104 A ITAVM (TC = 76°C); higher thermal resistance (0.185 °C/W) and lower tq (120 µs typ.). | Better suited for 1000 V AC line systems or higher-temperature ambient environments (>60°C), but less optimal for standard 690 V B6 rectifiers. | Choose DT92N14KOFHPSA1 when system voltage margin exceeds 1400 V or case temperature exceeds 85°C; otherwise TD92N1420KOFHPSA1 offers better thermal efficiency and proven B6 timing behavior. |
Compared with TT92N14KOFHPSA1 and DT92N14KOFHPSA1, TD92N1420KOFHPSA1 delivers optimal balance of dual-arm integration, 1400 V blocking, 92 A DC current handling at 85°C case, and 150 µs commutation timing-making it the preferred choice for standardized 690 V industrial rectifier designs where thermal efficiency and gate drive simplicity are prioritized.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies a maximum case temperature (TC) of 85°C for rated ITAVM = 92 A. At higher case temperatures, current must be linearly derated: ITAVM drops to 104 A at TC = 76°C (per DT92N variant), but TD92N1420KOFHPSA1 is characterized and guaranteed only up to 85°C for its 92 A rating. Exceeding this violates the thermal design boundary defined in Figure 7 of the datasheet.
Does TD92N1420KOFHPSA1 require forced cooling?
No-natural cooling is sufficient when mounted on a KM14 heatsink (50 W rating) with three modules per sink, as validated in the datasheet's thermal diagrams (Page 7). Forced cooling (e.g., Papst 4650N fan) extends current capability and allows tighter thermal margins but is not mandatory for 92 A DC operation at ambient ≤40°C.
Can this module be used in single-phase applications?
Yes-its dual-arm anti-parallel structure supports both single-phase (B2) and three-phase (B6) configurations. Page 8 of the datasheet provides explicit ID vs. RthCA curves for B2 operation, confirming rated output current up to 300 A at RthCA = 0.25 °C/W under natural cooling.
What gate drive voltage and current are required for reliable triggering?
A minimum gate trigger current of 0.6 A (not 120 mA) is required for guaranteed turn-on under worst-case conditions (Tvj max, vD = 0.67 VDRM), per IEC 747-6. The 120 mA rating applies only at Tvj = 25°C and vD = 6 V. Recommended gate drive: ≥15 V pulse with ≥2 A peak current and ≥20 µs width to ensure robust latching (IL = 620 mA) and avoid misfiring.
