Product details

Overview

TT330N16KOFTIMHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It delivers 330 A average on-state current at 85°C case temperature, 1600 V repetitive peak off-state voltage, and features pressure-contact die attachment for thermal and mechanical robustness. It is used in soft starters, static switches, and battery charger rectifiers where high surge immunity and reliable commutation are required.

For engineers reviewing the TT330N16KOFTIMHPSA1 datasheet, TT330N16KOFTIMHPSA1 pinout, TT330N16KOFTIMHPSA1 application, or TT330N16KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.106 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and pre-applied thermal interface material (TIM) integration.

Technical Context

This dual-thyristor module operates in phase-controlled AC applications with symmetrical forward/reverse blocking capability. Its 1600 V VDRM/VRRM rating supports medium-voltage industrial mains (e.g., 690 VAC 3-phase systems), while its 12.5 kA non-repetitive surge current (ITSM) enables crowbar protection during fault conditions.

The module uses Advanced Medium Power Technology (AMPT) with silicon pellets mounted via pressure contact-eliminating wire bonds and solder layers-to ensure stable thermal performance and long-term reliability under cyclic thermal stress. Its electrically insulated base plate (class I insulation per IEC61140) allows direct mounting to grounded heatsinks without additional isolation hardware.

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM / VRRM	1600 V - Enables use in 690 VAC 3-phase systems with ≥2.3× safety margin against transient overvoltages.
ITAVM (TC = 85°C)	330 A - Maximum continuous RMS-conducted current per arm under forced-air or liquid-cooled thermal management.
ITSM (10 ms)	12500 A - Supports short-circuit protection in motor drives and UPS rectifiers without device failure.
RthJC	0.106 K/W - Junction-to-case thermal resistance per arm; determines minimum heatsink requirement for safe operation at full load.
(dv/dt)cr	1000 V/µs - Critical rate of rise of off-state voltage; ensures reliable blocking during fast transients without false triggering.
VTO / rT	0.8 V / 0.5 mΩ - Threshold voltage and slope resistance define conduction loss profile; enables accurate power loss calculation in rectifier bridges.
q_t	250 µs typ. - Circuit-commutated turn-off time; sets minimum commutation interval in phase-controlled inverters and cycloconverters.

Pinout & Package

TT330N16KOFTIMHPSA1 is housed in an industrial-standard press-pack module with electrically insulated base plate and M1/M2 screw terminals. The package measures 50 mm × 50 mm footprint and weighs approximately 800 g. It contains two anti-parallel thyristor arms sharing a common isolated base plate.

Pin/Terminal	Circuit Role	Design Meaning
A1 (Anode 1)	Main anode of first thyristor arm	Carries full load current in one direction; rated for 330 A continuous, 12.5 kA surge.
K1 (Cathode 1)	Main cathode of first thyristor arm	Connects to load or DC bus; forms half-bridge leg with A2/K2 in B6 configurations.
A2 (Anode 2)	Main anode of second thyristor arm	Enables bidirectional conduction when paired with K1; supports full-wave rectification and AC switching.
K2 (Cathode 2)	Main cathode of second thyristor arm	Common return path for anti-parallel arm; shares thermal mass with A1/K1 via insulated base plate.
G1, G2	Gate terminals (separate per arm)	Isolated low-energy control inputs; require ≤2 V trigger voltage and ≤200 mA current for reliable turn-on.
Base Plate	Electrically insulated thermal interface	Class I isolation (3.6 kV RMS, 1 sec); pre-coated with TIM for optimized thermal coupling to heatsink.

Key Features

Feature	Design Value
Pressure contact die attachment	Eliminates bond wires and solder interlayers, improving thermal cycling endurance and reducing thermal resistance drift over lifetime.
Pre-applied thermal interface material (TIM)	Reduces assembly complexity and ensures repeatable, low-RthCH (0.015 K/W per module) without manual grease application.
Electrically insulated base plate	Enables direct mounting to grounded heatsinks without external insulators-reducing system size and parasitic capacitance.
Advanced Medium Power Technology (AMPT)	Optimizes trade-off between conduction loss (VT0 = 0.8 V) and switching robustness (q_t = 250 µs) for industrial drive duty cycles.

Applications

Soft Starter

Rectifier for Drives

Use Scenario: Gradual ramp-up of induction motor voltage during startup to limit inrush current and mechanical stress.

IC Role / Device Role / Timing Role: Phase-controlled thyristor pair regulates AC voltage amplitude by delaying conduction angle per half-cycle.

Use Value: Delivers precise torque control and eliminates contactor wear; leverages 12.5 kA ITSM to survive locked-rotor surges.

Use Scenario: AC-to-DC conversion in variable-frequency drive front-ends supplying DC link capacitors.

IC Role / Device Role / Timing Role: Dual-arm thyristor module configured as B6 six-pulse bridge for high-efficiency, low-harmonic rectification.

Use Value: Achieves >97% efficiency at 330 A output using low VT0 (0.8 V) and rT (0.5 mΩ) to minimize conduction losses.

Crowbar Protection

Static Switch

Use Scenario: Fast-acting overvoltage protection in UPS or generator excitation systems by shorting output during fault.

IC Role / Device Role / Timing Role: Thyristor triggered into full conduction to bypass load and divert fault current away from sensitive components.

Use Value: Relies on 1000 V/µs (dv/dt)cr and 250 µs q_t to ensure controlled, non-destructive crowbar activation under rapid transients.

Use Scenario: Solid-state replacement of electromechanical contactors in HVAC zone control or transformer tap changers.

IC Role / Device Role / Timing Role: Bidirectional AC switching element enabling zero-crossing or phase-angle control for load energization/de-energization.

Use Value: Provides silent, bounce-free switching with 1600 V blocking capability-suitable for 400–690 VAC distribution systems.

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
TT330N16KOF	No pre-applied TIM; RthCH increases to 0.02 K/W (vs. 0.015 K/W with TIM).	Requires manual thermal grease application; less suitable for high-volume automated assembly.	Select when TIM rework or custom interface materials are needed for specific thermal interface requirements.
TT500N16KOF	Higher ITAVM (500 A), larger package (62 mm × 62 mm), RthJC = 0.07 K/W.	Supports higher continuous power but requires larger heatsink and mounting space.	Select when system-level derating or future power scalability demands headroom beyond 330 A.

Compared with TT330N16KOF, TT330N16KOFTIMHPSA1 reduces thermal interface assembly steps and improves thermal repeatability; compared with TT500N16KOF, it offers optimal size–performance balance for 330 A-class industrial drives without over-engineering.

FAQ

What is the maximum allowable junction temperature for TT330N16KOFTIMHPSA1?

The maximum junction temperature (Tvj max) is 130°C, as specified in the Infineon technical information document revision 3.5. This limit applies under all operating conditions including surge events. Exceeding this temperature risks irreversible degradation of the silicon die and pressure-contact interface, especially during repeated thermal cycling.

Does TT330N16KOFTIMHPSA1 require external gate resistors for standard triggering?

Yes-gate resistors are required to limit peak gate current and ensure reliable turn-on within the specified IGT ≤ 200 mA and VGT ≤ 2 V limits. Typical values range from 10 Ω to 50 Ω depending on gate driver voltage and pulse width; omission may cause gate damage or inconsistent firing due to excessive diG/dt.

Can TT330N16KOFTIMHPSA1 be used in single-phase applications?

Yes-it supports single-phase configurations including half-wave and full-wave rectifiers, AC voltage controllers, and static relays. Its dual-arm structure allows flexible connection as a single switch or back-to-back pair; thermal derating must follow the ITAVM vs. conduction angle curves provided in the datasheet for non-180° operation.

What is the creepage distance and insulation rating of the base plate?

The creepage distance is 17 mm, and the base plate provides basic insulation (Class I per EN61140) with 3.6 kV RMS insulation test voltage for 1 second. This meets IEC61800-5-1 requirements for industrial drive systems and permits direct mounting to grounded heatsinks without supplemental isolation.
