Product details

Overview

TT330N16KOFHPSA2 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 (ITAVM) at TC = 85°C, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact die attachment for thermal and mechanical robustness. Used in soft starters, static switches, and UPS rectifiers where high surge immunity and reliable commutation are required.

For engineers reviewing the TT330N16KOFHPSA2 datasheet, TT330N16KOFHPSA2 pinout, TT330N16KOFHPSA2 application, or TT330N16KOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.106 K/W per arm), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and crowbar-capable surge rating (12.5 kA, 10 ms).

Technical Context

This dual-thyristor module operates in phase-controlled AC power regulation, enabling precise conduction-angle control in line-synchronized applications. Its pressure-contact construction ensures low parasitic inductance and stable RthJC (0.106 K/W per arm), supporting high di/dt (250 A/µs) and dv/dt (1000 V/µs) immunity during fast-switching transients.

The device integrates electrically insulated baseplate (class I insulation, 3.6 kV isolation test voltage) and supports optional pre-applied TIM for optimized thermal interface. Commutation behavior is characterized by 250 µs typical turn-off time (tq) under defined load and voltage conditions, enabling use in forced-commutated rectifier and crowbar circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM / VRRM	1600 V - Maximum repetitive blocking voltage per thyristor arm, defining safe operation in 1100–1380 VAC line applications with margin.
ITAVM (TC = 85°C)	330 A - Continuous RMS-conducted current per arm at heatsink temperature of 85°C, used for thermal sizing of cooling system.
ITSM (10 ms)	12500 A - Non-repetitive surge current capability, enabling short-circuit protection in motor starter and crowbar applications.
RthJC (per arm)	0.106 K/W - Junction-to-case thermal resistance under DC conditions, directly determining maximum allowable power dissipation at given TC.
(dv/dt)cr	1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on, critical for noise-immune gate triggering in EMI-prone environments.
tq (typ.)	250 µs - Typical circuit-commutated turn-off time at Tvj max, defining minimum commutation interval in forced-commutated rectifier topologies.
V(TO) / rT	0.8 V / 0.5 mΩ - Threshold voltage and slope resistance, jointly defining on-state conduction loss profile (vT = V(TO) + iT × rT) up to 800 A.

Pinout & Package

TT330N16KOFHPSA2 is housed in an industrial-standard press-pack module with electrically insulated baseplate and 50 mm × 70 mm footprint. Terminals are arranged for dual-arm configuration: two main AC terminals (A1/K1 and A2/K2), two gate terminals (G1 and G2), and isolated baseplate mounting surface.

Pin/Terminal	Circuit Role	Design Meaning
A1 / K1	Anode 1 / Cathode 1	Main current path for first thyristor arm; rated for full ITAVM and ITSM; requires low-inductance busbar connection.
A2 / K2	Anode 2 / Cathode 2	Main current path for second thyristor arm; electrically isolated from A1/K1; enables B2/B6 bridge configurations.
G1	Gate 1	Control input for first thyristor; requires ≤2 V trigger voltage and ≥1 A pulse current for reliable turn-on at Tvj max.
G2	Gate 2	Independent control input for second thyristor; galvanically isolated from G1; supports asymmetric firing in phase-control schemes.
Baseplate	Thermal & Electrical Reference	Electrically insulated (3.6 kV, 1 min), thermally conductive surface; must be mounted with specified torque (12 Nm for M2 terminals) and TIM if used.

Key Features

Feature	Design Value
Pressure-contact die attachment	Eliminates wire bonds and solder fatigue, delivering >10⁶ thermal cycles and stable RthJC over lifetime in high-vibration environments.
Electrically insulated baseplate	Class I basic insulation (IEC61140) with 3.6 kV/1 sec isolation rating, enabling direct mounting on grounded heatsinks without additional insulation.
Pre-applied TIM option	Reduces RthCH by up to 25% vs. bare interface (0.030 K/W vs. 0.040 K/W per arm), lowering case temperature rise under identical load.
Advanced Medium Power Technology (AMPT)	Optimized silicon layout and gate structure achieving 250 A/µs di/dt immunity and 1000 V/µs dv/dt immunity without snubbers in most line-frequency applications.

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
TT330N16KOFHPSA1	No pre-applied TIM; RthCH = 0.040 K/W (vs. 0.030 K/W with TIM in HPSA2)	Suitable for designs with custom thermal interface and tighter cost targets	Select when TIM application process is controlled internally and thermal margin >5°C is available.
TT500N16KOFHPSA2	Higher ITAVM (500 A), same VDRM (1600 V), higher RthJC (0.070 K/W per arm)	Required for >400 A continuous loads; needs larger heatsink due to lower thermal efficiency	Choose only when load current exceeds 360 A RMS and board-level space permits larger module footprint.

Compared with TT330N16KOFHPSA1, the HPSA2 offers lower thermal resistance via factory-applied TIM-critical for compact, fanless enclosures. Versus TT500N16KOFHPSA2, it trades current capacity for better thermal performance and smaller size, making it optimal for space-constrained 330–360 A applications.

FAQ

What is the maximum allowable junction temperature for TT330N16KOFHPSA2?

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, even if case temperature remains within spec.

Does TT330N16KOFHPSA2 require external snubber circuits?

Snubbers are not required for standard 50/60 Hz phase-control operation due to its 1000 V/µs critical dv/dt rating and 250 A/µs di/dt immunity. However, snubbers are recommended in high-di/dt applications such as inductive load switching or when used with long cable runs that increase stray inductance and voltage overshoot.

How is gate triggering implemented for dual-arm operation?

Each thyristor arm has an independent gate terminal (G1 and G2) with fully isolated control paths. Trigger pulses must be referenced to their respective cathodes (K1/K2), not common ground. The gate non-trigger voltage (VGD ≤ 0.2 V) and holding current (IH ≤ 300 mA) ensure noise immunity and stable latching after turn-on.

Can TT330N16KOFHPSA2 be used in parallel configurations?

Parallel operation is not recommended. The module uses pressure-contact technology optimized for single-arm thermal and current sharing; paralleling introduces imbalance due to parameter spread (VTO, rT) and unequal thermal coupling. For higher current, use higher-rated modules like TT500N16KOFHPSA2 or multi-module B6 bridge layouts with individual current balancing.
