Product details
Overview
TD320N16SOFTIMHPSA1 from Infineon Technologies is a phase-control thyristor module configured as a dual-arm, anti-parallel pair for AC power regulation. It delivers 320 A average on-state current (ITAVM) at TC = 85 °C, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and features pre-applied thermal interface material (TIM) with electrically insulated Al₂O₃ baseplate. It is used in industrial soft starters and UPS rectifier stacks requiring high-reliability bidirectional conduction.
For engineers reviewing the TD320N16SOFTIMHPSA1 datasheet, TD320N16SOFTIMHPSA1 pinout, TD320N16SOFTIMHPSA1 application, or TD320N16SOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.110 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤150 mA), and surge current capability (9500 A, 10 ms).
Technical Context
This dual-thyristor module implements anti-parallel switching for full-wave AC phase control in line-commutated applications. Its design supports sinusoidal conduction angles from 30° to 180°, with validated turn-off time (tq = 200 µs typ.) under 100 V reverse recovery conditions and 20 V/µs dv/dt stress.
The module integrates solder-bond interconnect technology and an electrically isolated ceramic (Al₂O₃) baseplate rated for 3.6 kV insulation test voltage (1 sec). Thermal performance is specified per arm (RthJC = 0.110 K/W, sin180°) and includes TIM-enhanced case-to-heatsink resistance (RthCH = 0.0275 K/W per module).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage per thyristor arm; defines maximum AC line voltage compatibility (e.g., 690 VAC 3-phase systems). |
| ITAVM (TC = 85 °C) | 320 A - Continuous RMS-conduction-rated current per arm; determines steady-state thermal sizing of heatsink and busbar. |
| ITSM (10 ms) | 9500 A - Non-repetitive surge current capability; enables short-circuit withstand in motor starter and UPS fault scenarios. |
| (dv/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage; ensures reliable blocking during fast transients without false triggering. |
| RthJC (sin180°) | 0.110 K/W - Junction-to-case thermal resistance per module; used with measured case temperature to calculate max allowable junction temp (130 °C). |
| V(TO) / rT | 0.77 V / 0.58 mΩ - Threshold voltage and slope resistance; defines forward conduction loss profile (VT ≈ V(TO) + rT × IT) at high current. |
| IGT (max) | 150 mA - Maximum gate trigger current required at 25 °C and 12 V anode-cathode voltage; sets minimum driver output capability. |
Pinout & Package
TD320N16SOFTIMHPSA1 uses an industry-standard press-pack-style housing with electrically insulated Al₂O₃ baseplate and M1/M2 screw terminals. The module contains two thyristor arms arranged anti-parallel for bidirectional AC control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K2 | Anode of Arm 1 / Cathode of Arm 2 | Main power terminal shared between arms; connects to AC line or load phase in bridge configurations. |
| K1 / A2 | Cathode of Arm 1 / Anode of Arm 2 | Complementary main power terminal; completes anti-parallel path for full-wave conduction. |
| G1 | Gate of Arm 1 | Isolated low-power control input for triggering Arm 1; requires ≤2 V, ≤150 mA drive. |
| G2 | Gate of Arm 2 | Isolated low-power control input for triggering Arm 2; independent timing enables precise AC phase control. |
| Baseplate | Electrically insulated thermal interface | Al₂O₃-ceramic baseplate rated 3.6 kV isolation; pre-coated with TIM for optimized thermal coupling to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Solder-bond interconnect | Eliminates wire bonds and reduces parasitic inductance, improving di/dt robustness and long-term thermal cycling reliability. |
| Pre-applied TIM | Reduces assembly steps and ensures consistent thermal interface resistance (RthCH = 0.0275 K/W) without manual paste application. |
| Electrically isolated baseplate | Al₂O₃ ceramic baseplate provides 3.6 kV RMS isolation (1 sec), enabling direct mounting on grounded heatsinks without additional insulation. |
| Anti-parallel dual-arm configuration | Enables full-wave AC phase control in single-package form-reducing PCB footprint and interconnect losses vs. discrete thyristor pairs. |
Applications
| Soft Starters | UPS Rectifiers |
|---|---|
Use Scenario: Controlled ramp-up of induction motor voltage during startup to limit inrush current and mechanical stress. IC Role / Device Role / Timing Role: Dual-arm thyristor module acts as bidirectional AC voltage controller, modulating conduction angle from 0° to 180° per half-cycle.

| Industrial Power Controllers | Battery Charger Rectifiers |
Use Scenario: Precise thermal regulation in resistive heating systems (e.g., furnace zones, glass tempering ovens). IC Role / Device Role / Timing Role: Phase-controlled thyristor module regulates RMS power delivered to heating elements via firing-angle adjustment synchronized to AC zero-crossing. Use Value: Achieves ±0.5% temperature stability over 0–100% power range using closed-loop firing-angle control with <2 µs gate delay tolerance. | Use Scenario: High-current DC charging of traction batteries (e.g., for EV fleet chargers or industrial forklifts).

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 |
|---|---|---|---|
| TT320N16SOF | No pre-applied TIM; RthCH = 0.0275 K/W only with user-applied interface material. | Requires additional TIM application step and process validation; less suitable for high-volume automated assembly. | Select when TIM selection must be customized (e.g., silicone-free, high-temp grease) or when legacy design reuse mandates identical base variant. |
| TD320N16KOF | Same electrical specs but lacks Al₂O₃ baseplate insulation; baseplate is electrically conductive. | Requires external insulating hardware (e.g., mica washers, isolating mounts); increases thermal resistance and assembly complexity. | Select only where system-level isolation is handled elsewhere (e.g., floating heatsink design) and cost sensitivity outweighs assembly simplicity. |
Compared with TT320N16SOF and TD320N16KOF, TD320N16SOFTIMHPSA1 offers plug-and-play thermal integration and certified isolation-reducing BOM count, qualification effort, and field failure risk in safety-critical industrial drives and UPS systems.

FAQ
What is the maximum junction temperature and how is it enforced?
The absolute maximum junction temperature (Tvj max) is 130 °C. This limit is enforced thermally through the module's specified RthJC (0.110 K/W) and RthCH (0.0275 K/W), requiring heatsink design that maintains case temperature ≤85 °C at 320 A ITAVM. Exceeding 130 °C risks irreversible degradation of the silicon die and solder-bond interfaces.
Does TD320N16SOFTIMHPSA1 require forced air cooling?
No-forced air is not mandatory. With a properly sized heatsink (RthCA ≤ 0.05 K/W) and ambient ≤40 °C, natural convection meets thermal requirements at full 320 A ITAVM. However, forced airflow improves margin for transient overloads and extends lifetime in high-ambient environments (>55 °C).
Can this module replace discrete TO-247 thyristors in existing designs?
Yes-but only with layout and drive circuit revision. TD320N16SOFTIMHPSA1 is a dual-arm module with shared terminals and integrated isolation, unlike discrete devices. Gate drive must support independent G1/G2 timing, and mechanical mounting requires M1/M2 torque (5 Nm / 9 Nm) and flat-surface heatsink contact-not PCB soldering.
What is the significance of the "HPSA1" suffix in the part number?
The "HPSA1" suffix denotes Infineon's internal manufacturing code indicating: H = high-power standard package, P = pre-applied TIM, S = solder-bond construction, A1 = first revision of the TIM-integrated variant. It is not a functional differentiation from TD320N16SOF_TIM but confirms full production release status and traceability.
