Product details

Overview

TT330N14KOFHPSA2 from Infineon Technologies is a pressure-contact thyristor module for phase-controlled AC power regulation in industrial drive rectifiers and soft starters. It delivers 330 A average on-state current (ITAVM) at TC = 85°C, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and features electrically insulated baseplate with pre-applied TIM option for thermal interface reliability in high-power static switch applications.

For engineers reviewing the TT330N14KOFHPSA2 datasheet, TT330N14KOFHPSA2 pinout, TT330N14KOFHPSA2 application, or TT330N14KOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (RthJC = 0.106 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (IGT ≤ 200 mA), and crowbar-capable surge current (ITSM = 12.5 kA, 10 ms).

Technical Context

This dual-thyristor module implements phase-angle control in line-commutated bridge configurations (B2/B6), supporting both rectifier and static switching functions. Its pressure-contact die attachment ensures stable thermal performance under high di/dt (250 A/µs) and dv/dt (1000 V/µs) transients, with commutated turn-off time (tq) of 250 µs at Tvj = 130°C.

The module integrates two inverse-parallel thyristor arms in a single industrial-standard package, rated for 130°C maximum junction temperature and -40°C to +130°C operating case temperature range. Electrical isolation (3.6 kV RMS, 1 sec) and creepage distance (17 mm) meet IEC61140 Class 1 safety requirements for mains-connected equipment.

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM / VRRM	1600 V - Maximum repetitive blocking voltage per thyristor arm, enabling use in 690 V AC three-phase systems with margin.
ITAVM (TC = 85°C)	330 A - Continuous average on-state current per arm, defining steady-state conduction capability in rectifier or controller topologies.
ITSM (10 ms)	12500 A - Non-repetitive surge current rating, supporting short-circuit protection and crowbar operation in UPS or drive fault conditions.
RthJC	0.106 K/W - Junction-to-case thermal resistance per module, used to calculate max allowable power dissipation at given heatsink temperature.
(dv/dt)cr	1000 V/µs - Critical rate of rise of off-state voltage, determining immunity to false triggering from fast transients in noisy industrial environments.
VTO / rT	0.8 V / 0.5 mΩ - Threshold voltage and slope resistance, defining forward conduction loss profile and enabling accurate on-state loss modeling.
tq (commutated)	250 µs - Circuit commutated turn-off time at Tvj = 130°C, critical for designing forced-commutation timing in static switches and inverters.

Pinout & Package

TT330N14KOFHPSA2 uses an industrial-standard press-pack module package with electrically insulated baseplate (AlN ceramic), 50 mm baseplate dimension, and M1 (5 N·m) mechanical mounting torque. Terminal layout follows dual-arm configuration: main terminals T1/T2 for AC input/output, gate terminals G1/K1 and G2/K2 for independent arm control.

Pin/Terminal	Circuit Role	Design Meaning
T1	Anode of Arm 1	Main current path entry for first thyristor arm; connected to AC line or load depending on topology (e.g., B2/B6 rectifier).
T2	Cathode of Arm 2	Main current path exit for second thyristor arm; completes conduction path in inverse-parallel configuration.
G1, K1	Gate & Cathode of Arm 1	Isolated gate drive interface for Arm 1; requires ≤2 V trigger voltage and supports ≤200 mA trigger current.
G2, K2	Gate & Cathode of Arm 2	Independent gate drive interface for Arm 2; enables phase-shifted or complementary firing in full-bridge control schemes.

Key Features

Feature	Design Value
Pressure contact die attachment	Eliminates wire bonds and solder layers, ensuring stable RthJC and long-term reliability under thermal cycling in industrial drives.
Electrically insulated baseplate (AlN)	Provides 3.6 kV RMS isolation between semiconductor die and heatsink, removing need for isolating thermal pads in grounded-chassis designs.
Pre-applied TIM option	Reduces assembly variability and thermal interface resistance by up to 33% versus field-applied grease, improving thermal margin in high-volume production.
Advanced Medium Power Technology (AMPT)	Optimizes trade-off between conduction loss (VT0 = 0.8 V) and switching robustness (dv/dt = 1000 V/µs), targeting medium-power industrial controls.

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
TT330N16KOFHPSA2	Higher VDRM/VRRM (1600 V vs. 1400 V in TT330N14KOFHPSA2); identical ITAVM, RthJC, and package.	Supports higher AC system voltages (e.g., 690 V with increased safety margin); same thermal and gate drive behavior.	Select when operating in 690 V AC grids requiring ≥2× system voltage derating for transient immunity.
TD330N14KOFHPSA2	Single-arm configuration (vs. dual-arm); identical VDRM, ITAVM, and thermal specs; no inverse-parallel pairing.	Requires external anti-parallel device for AC switching; suitable for half-wave or DC chopper topologies only.	Choose for unidirectional applications like battery charger rectifiers where reverse conduction is handled separately.

Compared with TT330N14KOFHPSA2, TT330N16KOFHPSA2 offers enhanced voltage margin without thermal or gate drive changes, while TD330N14KOFHPSA2 reduces integration level but increases design flexibility for non-AC-switching roles.

FAQ

What is the maximum allowable case temperature for continuous operation?

The TT330N14KOFHPSA2 supports continuous operation up to +130°C case temperature (Tc op), as specified in its thermal characteristics table. At this temperature, the device maintains 330 A ITAVM rating only when mounted on a heatsink with RthCH ≤ 0.04 K/W and using pre-applied TIM. Derating applies above 85°C ambient if heatsink thermal resistance exceeds design limits.

Does this module require external snubber circuits?

Snubbers are recommended due to the module's 1000 V/µs (dv/dt)cr rating. In B6 rectifier applications with inductive loads, RC snubbers across each thyristor arm suppress voltage overshoot during commutation. The datasheet provides snubber design guidelines based on load L/R ratio and expected di/dt, with typical values of 0.1 µF + 22 Ω per arm.

How is gate drive isolation implemented in this module?

Each gate terminal (G1/K1 and G2/K2) is galvanically isolated from the main terminals and baseplate. Isolation is achieved via internal creepage distance (17 mm) and reinforced insulation (3.6 kV RMS, 1 sec), allowing direct connection to optocoupled or transformer-isolated gate drivers without additional barrier components.

Can TT330N14KOFHPSA2 be paralleled with other modules for higher current?

Parallel operation is not recommended. The module lacks built-in current-sharing features such as matched VTO/rT or integrated emitter resistors. Even with matched units, thermal coupling differences and gate propagation delays cause unequal current division. For >330 A, use higher-rated modules (e.g., TT600N series) instead of paralleling.
