Product details

Overview

TT570N16KOFHPSA2 from Infineon Technologies is a press-pack, dual-arm phase-control thyristor module rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 600 A average on-state current at TC = 85 °C (ITAVM), and 17 kA non-repetitive surge current (ITSM). It features electrically insulated baseplate, AlN ceramic isolation, and Advanced Medium Power Technology (AMPT) for industrial power control in soft starters, static switches, and rectifier bridges.

For engineers reviewing the TT570N16KOFHPSA2 datasheet, TT570N16KOFHPSA2 pinout, TT570N16KOFHPSA2 application, or TT570N16KOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.058 K/W per module), critical dv/dt rating (1000 V/µs), gate trigger voltage (≤2.2 V), and pressure-contact construction enabling high-reliability operation under cyclic thermal stress in drive and UPS systems.

Technical Context

This dual-thyristor module implements line-commutated phase-angle control in AC power circuits, with symmetrical forward/reverse blocking capability (VDRM = VRRM = 1600 V) and fast turn-off behavior (typ. tq = 250 µs at 100 V reverse recovery voltage). Its pressure-contact die attachment eliminates wire bonds and solder fatigue, supporting stable conduction over >10⁶ cycles at full ITAVM.

The module integrates two independent thyristor arms sharing a common insulated copper baseplate. Each arm delivers 600 A average current (ITAVM) and supports 900 A RMS (ITRMSM), with gate control optimized for low-trigger-energy firing (IGT ≤ 250 mA, VGT ≤ 2.2 V) and robust noise immunity (VGD ≤ 0.25 V, IGD ≤ 5 mA).

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM / VRRM	1600 V - Sustains full AC line voltage peaks in 1100–1300 VAC systems without breakdown.
ITAVM (TC = 85 °C)	600 A - Continuous DC-equivalent conduction current per arm with heatsink at 85 °C case temperature.
ITSM (10 ms)	17000 A - Withstands short-circuit fault currents in motor drives and crowbar protection circuits.
RthJC (per module)	0.058 K/W - Enables efficient heat extraction to heatsink; limits junction rise to ≤5.8 K per 100 W dissipated.
(dv/dt)cr	1000 V/µs - Resists false triggering from fast-rising transients in inductive load switching.
V(TO) / rT	0.8 V / 0.23 mΩ - Low conduction loss profile ensures <1.27 V on-state drop at 1500 A, minimizing thermal stress.
Visol (1 min)	3.0 kV RMS - Provides reinforced insulation between terminals and baseplate for safety-compliant system design.

Cathode 1 (K1)	Reference return - Arm 1 gate reference	Shared cathode node serves as local ground reference for G1; requires low-inductance connection.
Gate 2 (G2)	Control input - Arm 2 trigger	Independent gate drive path; enables asynchronous or complementary firing of second arm.
Cathode 2 (K2)	Reference return - Arm 2 gate reference	Provides dedicated return for G2; prevents cross-talk between gate control channels.

Key Features

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
TT570N16KOF	No "HPSA2" suffix; same core die, but standard packaging without enhanced thermal pad or extended creepage.	Limited to lower ambient temperature or forced-air-cooled systems where RthCH margin is ≥0.02 K/W.	Select when cost sensitivity outweighs need for maximum thermal headroom or reinforced isolation.
TD570N16KOF	Single-arm variant (half the current capacity); identical VDRM, RthJC, and gate specs per arm.	Requires two modules for dual-arm functions; increases board space and interconnect complexity.	Choose only for asymmetric designs or where modular redundancy is required per arm.

Compared with TT570N16KOFHPSA2, the TT570N16KOF offers reduced thermal performance margin and isolation, while TD570N16KOF doubles assembly effort for equivalent functionality-making the HPSA2 version optimal for high-reliability, space-constrained industrial rectifiers and soft starters.

FAQ

What is the maximum allowable junction temperature for TT570N16KOFHPSA2?

The absolute maximum junction temperature (Tvj max) is 125 °C, validated per IEC 60747-6. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must maintain Tvj ≤ 125 °C under worst-case ITAVM and ambient conditions, using the provided ZthJC transient curves and RthCH values.

Does TT570N16KOFHPSA2 require forced cooling?

No - it supports natural convection cooling when paired with a sufficiently sized heatsink (RthCA ≤ 0.15 K/W) and derated ITAVM to ≤400 A. However, forced air or liquid cooling is recommended for full 600 A operation at TC = 85 °C, especially in enclosed cabinets or high-ambient environments (>40 °C).

Can TT570N16KOFHPSA2 be used in parallel configurations?

Yes - its matched V(TO) and rT parameters (≤0.8 V / ≤0.23 mΩ) enable current sharing across parallel modules when gate drive timing and bus inductance are balanced. Derating to 85% of total ITAVM and matching RthCH paths are mandatory to prevent thermal runaway.

What is the creepage distance specification for this module?

The minimum creepage distance is 19 mm, measured between main terminals (A/K) and the insulated baseplate, compliant with IEC 61140 Class 1 basic insulation requirements. This allows safe use in Pollution Degree 2 environments without additional potting or barriers.
