Product details
Overview
TD820N16KOFXPSA1 from Infineon Technologies is a press-pack, dual-thyristor phase-control module rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 820 A average on-state current at TC = 85°C (ITAVM), and 24.8 kA non-repetitive surge current (ITSM). It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and Advanced Medium Power Technology (AMPT) for industrial power control in soft starters and static switches.
For engineers reviewing the TD820N16KOFXPSA1 datasheet, TD820N16KOFXPSA1 pinout, TD820N16KOFXPSA1 application, or TD820N16KOFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.045 K/W per arm), critical dv/dt rating (1000 V/µs), gate trigger current (≤250 mA), and pressure-contact construction enabling high-reliability operation under cyclic thermal stress in drive rectifier and crowbar circuits.
Technical Context
This dual-thyristor module implements phase-angle control in AC line-commutated applications, with symmetrical forward/reverse blocking capability (VDRM = VRRM = 1600 V) and validated turn-off behavior (typ. tq = 250 µs at Tvj max, vRM = 100 V). Its pressure-contact die attachment eliminates wire bonds and solder fatigue, supporting >10⁵ thermal cycles in high-current industrial environments.
The device operates with gate-controlled triggering (IGT ≤ 250 mA, VGT ≤ 2 V) and exhibits defined on-state characteristics governed by VT0 = 0.8 V and rT = 0.23 mΩ at Tvj max. Thermal design relies on validated transient impedance ZthJC data (7-element Foster network) and DC thermal resistance of 0.045 K/W per arm for heatsink sizing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage in both directions, defining safe AC line voltage rating up to 1150 V RMS. |
| ITAVM (TC = 85°C) | 820 A - Continuous average on-state current per arm at case temperature 85°C, used for steady-state thermal design. |
| ITSM (10 ms) | 24800 A - Non-repetitive surge current capability, determining short-circuit withstand in motor starter crowbar protection. |
| RthJC (per arm) | 0.045 K/W - Junction-to-case thermal resistance under DC conditions, directly used to calculate maximum allowable junction temperature. |
| (dvD/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on, requiring snubber design for inductive loads. |
| VT0 / rT | 0.8 V / 0.23 mΩ - Threshold voltage and slope resistance defining on-state conduction loss model: vT = VT0 + rT × iT. |
| Visol (1 min) | 3.0 kV RMS - Insulation test voltage between terminals and baseplate, confirming reinforced isolation for 690 V AC systems. |
Pinout & Package
TD820N16KOFXPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN-ceramic baseplate (60 mm × 60 mm footprint) and two isolated thyristor arms. Mechanical mounting uses M1 screws (6 Nm torque); electrical terminals are M2 (12 Nm) for main current paths and DIN 46244 A-style control terminals (2.8 × 0.8 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Main current input for Arm 1 | High-current terminal rated for ≥820 A continuous; requires low-inductance busbar connection. |
| Cathode 1 (K1) | Main current output for Arm 1 | Paired with A1 to form first thyristor arm; shares common baseplate isolation. |
| Anode 2 (A2) | Main current input for Arm 2 | Independent second arm for full-wave or dual-phase control; galvanically isolated from Arm 1. |
| Cathode 2 (K2) | Main current output for Arm 2 | Enables B2 (two-pulse) or B6 (six-pulse) bridge configurations without external isolation. |
| Gate 1 (G1) | Trigger control for Arm 1 | Low-energy gate input (≤250 mA IGT); requires isolated driver referenced to K1 potential. |
| Cathode 1 (K1) | Reference for Gate 1 | Gate return path; must be routed with minimal loop area to avoid false triggering. |
| Gate 2 (G2) | Trigger control for Arm 2 | Independent gate input; timing separation enables phase-shifted firing in multi-pulse rectifiers. |
| Cathode 2 (K2) | Reference for Gate 2 | Isolated gate return; prevents cross-talk between arms during commutation. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact die attachment | Eliminates bond wires and solder layers, enabling >10⁵ thermal cycles and zero interfacial delamination risk under 820 A load. |
| Electrically insulated baseplate (AlN) | Provides 3.0 kV RMS isolation between power terminals and heatsink, eliminating need for isolating thermal pads in grounded-chassis designs. |
| Pre-applied TIM | Reduces RthCH by 25% vs. bare surface (0.0075 K/W vs. 0.01 K/W per module), lowering junction temperature rise by ~12°C at full load. |
| Advanced Medium Power Technology (AMPT) | Optimizes carrier lifetime and emitter efficiency to achieve 0.23 mΩ slope resistance while maintaining 1000 V/µs dv/dt immunity. |
| Validated commutation turn-off time | tq = 250 µs (typ.) at Tvj max ensures reliable forced commutation in static transfer switches and UPS bypass circuits. |

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 |
|---|---|---|---|
| TT820N16KOF | Same die, identical VDRM/ITAVM/RthJC, but non-insulated baseplate and no pre-applied TIM. | Requires external isolation kit and thermal pad; unsuitable for direct-mount to grounded heatsinks. | Select when cost sensitivity outweighs assembly labor and isolation assurance requirements. |
| TD1000N16KOF | Higher ITAVM (1000 A), same VDRM (1600 V), increased RthJC (0.036 K/W per arm), heavier package (1.8 kg). | Supports higher continuous load in space-constrained cabinets but demands larger heatsink mass. | Select when system duty cycle exceeds 85% and ambient temperature exceeds 55°C. |
Compared with TT820N16KOF, TD820N16KOFXPSA1 adds baseplate insulation and TIM for simplified thermal management and safety compliance; compared with TD1000N16KOF, it trades 180 A current headroom for lower weight and tighter footprint-ideal for retrofit upgrades in existing 820 A-rated enclosures.

FAQ
What is the maximum allowable junction temperature for TD820N16KOFXPSA1?
The maximum junction temperature (Tvj max) is 135°C, validated per IEC 60747-6. This limit governs thermal design when combined with RthJC = 0.045 K/W per arm and measured case temperature. Exceeding 135°C risks irreversible degradation of the silicon die and pressure-contact interface.
Can TD820N16KOFXPSA1 be used in a single-phase full-wave rectifier configuration?
Yes-it supports single-phase full-wave (B2) rectification using both arms with common cathode or common anode topology. The datasheet provides derating curves for ITAVM up to 1200 A in B2 mode at Θ = 180° conduction, with total power loss calculated separately for each arm.
Does the pre-applied TIM require additional thermal compound during installation?
No. The TIM layer is factory-applied and optimized for direct metal-to-ceramic contact. Adding extra grease or pad degrades thermal performance and violates Infineon's qualified mounting process. Only clean, flat, and dry heatsink surfaces should contact the baseplate.
What gate drive voltage and current are required to reliably trigger TD820N16KOFXPSA1?
A minimum gate trigger voltage of 2 V and current of 250 mA (at Tvj = 25°C, vD = 12 V) ensures turn-on under worst-case conditions. Gate pulses must exceed 20 µs duration and maintain diG/dt ≥ 1 A/µs to prevent misfiring during high dv/dt transients.
