Product details
Overview
DT250N16KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 1600 V repetitive peak off-state voltage (VDRM/VRRM), 250 A average on-state current at TC = 85 °C, 8000 A non-repetitive surge current, and pressure-contact construction for thermal and mechanical robustness - deployed in soft starters and static power controllers.
For engineers reviewing the DT250N16KOFHPSA1 datasheet, DT250N16KOFHPSA1 pinout, DT250N16KOFHPSA1 application, or DT250N16KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), gate trigger current (≤200 mA), critical dv/dt rating (1000 V/µs), and electrically insulated baseplate compatibility with forced-air or liquid-cooled heatsinks.
Technical Context
This double thyristor module implements a back-to-back (anti-parallel) configuration for full-wave AC phase control, enabling bidirectional conduction without external commutation circuitry. Its pressure-contact die attachment ensures low parasitic inductance and stable thermal performance under high di/dt (150 A/µs) and high dv/dt (1000 V/µs) transients.
The device operates with gate-controlled turn-on only; it lacks self-commutation capability and requires external circuitry for forced commutation or zero-crossing turn-off. Thermal design must account for transient impedance ZthJC (0.124 K/W DC, with analytical RC network parameters provided for dynamic loss modeling).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage per thyristor arm; defines maximum AC line voltage (e.g., 690 VAC 3-phase systems with safety margin) |
| ITAVM (TC = 85 °C) | 250 A - Continuous RMS-conducted current per arm at heatsink temperature of 85 °C; sets steady-state power handling limit |
| ITSM (10 ms) | 8000 A - Non-repetitive surge current capability; supports motor inrush and short-circuit fault ride-through |
| RthJC | 0.124 K/W - Junction-to-case thermal resistance per arm; determines minimum heatsink requirement for thermal stability |
| (dv/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on; mandates snubber design for inductive loads |
| VGT / IGT | ≤2 V / ≤200 mA - Maximum gate trigger voltage and current at 25 °C; defines driver output capability requirement |
| tq (turn-off time) | 250 µs typical - Circuit commutated turn-off time at max junction temperature; constrains maximum operating frequency in phase-control mode |

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 |
|---|---|---|---|
| TT250N16KOFHPSA1 | Same die, identical VDRM/VRRM (1600 V), ITAVM (250 A), and RthJC (0.124 K/W); differs only in prefix (TT vs DT) - confirmed as same production variant per Infineon short-form catalog. | No functional difference; used interchangeably in soft starter and rectifier designs requiring same thermal and electrical specs. | Select when sourcing from distributors listing TT-prefix stock; identical mounting, wiring, and thermal interface requirements. |
| TD250N16KOFHPSA1 | Identical electrical ratings but rated for lower case temperature (TC = 82 °C vs 85 °C for DT-series); RthJC remains 0.124 K/W, implying tighter thermal derating above 82 °C. | Suitable for lower ambient or forced-cooled environments where case temperature stays ≤82 °C; not recommended for natural convection or high-ambient deployments. | Choose only if thermal management guarantees sustained TC ≤82 °C; otherwise DT-series provides 3 °C higher operational margin. |
Compared with TT250N16KOFHPSA1, DT250N16KOFHPSA1 offers identical performance with no trade-offs, while TD250N16KOFHPSA1 requires stricter thermal control to maintain rated current - making DT the preferred choice for general-purpose industrial power control where case temperature may exceed 82 °C.

FAQ
Is DT250N16KOFHPSA1 compatible with standard DIN-rail mounted heatsinks?
No - this module uses an industrial press-pack package with M1 mounting screws and a 50 mm × 70 mm baseplate footprint, designed for bolt-down installation onto custom-machined or flat-plate heatsinks. It does not conform to DIN 43880 or DIN 43881 rail-mount form factors. Mechanical mounting requires torque-controlled tightening to 5 Nm for M1 screws and 12 Nm for M2 terminals.
What gate drive voltage and current are required for reliable turn-on?
A minimum gate trigger voltage of 2 V and peak current of 200 mA at 25 °C is required for guaranteed turn-on; gate pulse width must exceed 20 µs. At elevated junction temperatures (125 °C), gate sensitivity decreases - recommend ≥3 V and ≥300 mA drive capability with <1 µs rise time to ensure margin across temperature and aging.
Can DT250N16KOFHPSA1 be used in single-phase versus three-phase configurations?
Yes - the anti-parallel thyristor pair supports both topologies: in single-phase, it controls one AC line leg; in three-phase, two modules configure a half-bridge per phase (B6 six-pulse) or one module per phase leg in phase-angle controlled rectifiers. Derating applies based on conduction angle and thermal resistance to ambient (RthCA).
Does the module include built-in overtemperature protection?
No - DT250N16KOFHPSA1 has no integrated temperature sensor or shutdown logic. Safe operation requires external thermal monitoring via thermistor or RTD mounted on the baseplate, with trip threshold set below 125 °C maximum junction temperature. Infineon specifies Tc op range of −40 °C to +125 °C, but thermal runaway begins near 135 °C.
