Infineon Technologies TD570N16KOFHPSA2

Overview

TD570N16KOFHPSA2 from Infineon Technologies is a pressure-contact thyristor module for phase-controlled AC power regulation, featuring 1600 V repetitive peak off-state voltage (VDRM/VRRM), 600 A average on-state current (ITAVM) at TC = 85 °C, and 17 kA non-repetitive surge current (ITSM). It is electrically insulated, rated for 125 °C junction temperature, and used in industrial soft starters and static power controllers.

For engineers reviewing the TD570N16KOFHPSA2 datasheet, TD570N16KOFHPSA2 pinout, TD570N16KOFHPSA2 application, or TD570N16KOFHPSA2 equivalent, key selection criteria include gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 2.2 V), thermal resistance (RthJC = 0.058 K/W per module), critical dv/dt (1000 V/µs), and isolation rating (3.6 kV RMS/1 sec).

Technical Context

This dual-thyristor phase control module implements forced commutation-capable silicon elements with pressure-contact interconnection, enabling high-current handling without wire bonds. Its design supports 180° conduction angle operation with DC, rectified, and sinusoidal load currents up to 900 A RMS (ITRMSM).

The module integrates basic insulation per IEC 61140 Class 1 and uses aluminum nitride (AlN) substrate for thermal management. Gate drive requirements are defined by triggering area curves at VD = 12 V, with critical di/dt (200 A/µs) and dv/dt (1000 V/µs) limits ensuring reliable turn-on and blocking stability.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is +125 °C for full-rated ITAVM = 600 A under 180° conduction angle with DC or sinusoidal current. Derating is required above this temperature, as shown in the TC = f(ITAVM) curve on page 7 of the technical information document. Operation beyond 125 °C risks irreversible degradation of the AlN insulation and silicon die.

How should the gate terminals be driven to ensure reliable triggering?

Gate terminals G1 and G2 require ≥1 A pulse current with diG/dt ≥ 1 A/µs and minimum pulse width tg ≥ 20 µs to guarantee latching at 1500 mA IL. Trigger voltage must exceed VGT ≤ 2.2 V at 25 °C, and gate circuits must include RC snubbers to suppress dv/dt-induced false turn-on, especially given the high (dvD/dt)cr = 1000 V/µs rating.

Can TD570N16KOFHPSA2 be used in parallel configurations?

No-this module is not designed for paralleling. Its pressure-contact construction and inherent parameter spread (e.g., VTO, rT) make current sharing unreliable without active balancing. Infineon specifies single-module use only; for higher current, select higher-rated modules like TD740N16KOFHPSA2 instead of paralleling.

What is the significance of the "HPSA2" suffix in the part number?

The "HPSA2" suffix denotes Infineon's internal revision and packaging variant: "H" = high-isolation version (3.6 kV), "P" = pressure-contact construction, "SA" = standard industrial package with AlN insulation, and "2" = second-generation assembly process with tightened gate parameter tolerances and improved thermal interface consistency.
