Product details
Overview
TD250N14KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching in industrial power electronics. It delivers 250 A average on-state current at 85 °C case temperature, supports 1400 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact silicon die construction with electrically insulated baseplate. It is used in soft starters, static switches, and rectifier bridges for drive systems.
For engineers reviewing the TD250N14KOFHPSA1 datasheet, TD250N14KOFHPSA1 pinout, TD250N14KOFHPSA1 application, or TD250N14KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and surge current capability (9100 A, 10 ms).
Technical Context
This dual-thyristor module operates in phase-controlled AC applications where precise conduction-angle regulation enables adjustable power delivery to resistive or inductive loads. Its pressure-contact die assembly ensures low thermal resistance and high mechanical robustness under repeated thermal cycling.
The device supports both two-pulse (B2) and six-pulse (B6) bridge configurations, with validated performance up to 125 °C junction temperature and isolation test voltage of 3.0 kV RMS (1 min). Gate control requires ≤2 V trigger voltage and tolerates non-trigger voltages up to 0.2 V at full blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1400 V - Maximum repetitive forward/reverse blocking voltage per thyristor arm; defines safe AC line voltage rating in B2/B6 rectifiers. |
| ITAVM (TC = 85 °C) | 250 A - Continuous average on-state current per arm; sets steady-state power handling in soft starters and power controllers. |
| ITSM (10 ms) | 9100 A - Non-repetitive surge current capability; determines short-circuit withstand in crowbar or motor-start fault conditions. |
| RthJC | 0.124 K/W - Junction-to-case thermal resistance per arm; enables thermal design of heatsink interface for 125 °C max junction operation. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; defines minimum snubber requirements to prevent false triggering. |
| V(TO) / rT | 0.8 V / 0.7 mΩ - Threshold voltage and slope resistance; jointly determine on-state conduction loss profile at rated current. |
| tq (typ.) | 250 µs - Circuit commutated turn-off time; constrains maximum operating frequency in forced-commutated inverters or choppers. |
Pinout & Package
TD250N14KOFHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN ceramic baseplate (50 mm × 50 mm footprint). The package uses pressure-contact technology-no wire bonds-and features isolated main terminals and separate gate control terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K2 | Anode 1 / Cathode 2 | Main current terminals for first thyristor arm; configured as common-anode pair in B6 bridge topology. |
| K1 / A2 | Cathode 1 / Anode 2 | Main current terminals for second thyristor arm; forms complementary arm for full-wave control. |
| G1 / G2 | Gate 1 / Gate 2 | Isolated low-energy gate inputs; require ≤200 mA trigger current and tolerate ≤0.2 V non-trigger voltage at full blocking. |
| Baseplate | Thermal & Electrical Reference | Electrically insulated (3.0 kV RMS, 1 min), thermally conductive surface; must be mounted with TIM or thermal paste for RthCH ≤ 0.04 K/W. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact die assembly | Eliminates wire bonds and solder layers, reducing thermal fatigue and enabling >10⁵ thermal cycles at ΔTj = 100 K. |
| Electrically insulated baseplate | AlN ceramic substrate rated for 3.0 kV RMS isolation; removes need for external insulating washers in chassis-grounded heatsinks. |
| Pre-applied TIM option | Reduces RthCH by ≥25% vs. standard mounting; achieves 0.015 K/W (per module) with validated long-term adhesion stability. |
| High dv/dt immunity | 1000 V/µs critical off-state voltage rise rate supports direct connection to fast-switching IGBT inverters without added snubbers. |

FAQ
What is the maximum allowable junction temperature for TD250N14KOFHPSA1?
The absolute maximum junction temperature (Tvj max) is 125 °C, as specified in the Infineon technical information document revision 3.6. Operation beyond this limit risks irreversible degradation of the pressure-contact die interface and increased leakage current. Thermal design must ensure junction temperature remains below 125 °C under worst-case ITAVM and ambient conditions.
Does TD250N14KOFHPSA1 require external snubber circuits?
Snubbers are required only when applied dv/dt exceeds 1000 V/µs-the device's critical off-state voltage rise rate. In standard 50/60 Hz phase-control applications with typical line impedances, no snubber is needed. However, in high-dv/dt environments (e.g., IGBT-fed inverters), RC snubbers must be sized to limit dv/dt below this threshold to prevent false triggering.
How is gate drive isolation implemented for TD250N14KOFHPSA1?
Gate terminals G1 and G2 are electrically isolated from the main current path and baseplate. Each gate requires ≤2 V trigger voltage and ≤200 mA current, with galvanic separation maintained via internal creepage distance (17 mm) and reinforced insulation. External gate drivers must provide ≥3.0 kV RMS isolation to match the module's basic insulation rating.
Can TD250N14KOFHPSA1 be used in parallel configurations?
No-this module is not designed for paralleling. Its pressure-contact architecture lacks inherent current-sharing characteristics, and gate threshold matching between units is not guaranteed. For higher current ratings, Infineon specifies dedicated higher-current modules (e.g., TD330N14KOF) rather than parallel arrangements of TD250N variants.
