Infineon Technologies TZ600N14KOFHPSA1

Overview

TZ600N14KOFHPSA1 from Infineon Technologies is a phase-control thyristor module with dual anti-parallel SCR configuration, rated for 1400 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 employs pressure-contact technology, features an electrically insulated AlN baseplate, and is designed for high-power AC line control in industrial drive rectifiers and soft starters.

For engineers reviewing the TZ600N14KOFHPSA1 datasheet, TZ600N14KOFHPSA1 pinout, TZ600N14KOFHPSA1 application, or TZ600N14KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.062 K/W), threshold voltage (0.9 V), slope resistance (0.27 mΩ), critical dv/dt rating (1000 V/µs), and gate trigger current (≤250 mA) under standard test conditions.

Technical Context

This dual SCR module operates in phase-controlled AC power circuits, enabling precise conduction-angle regulation for voltage and power adjustment. Its pressure-contact die attachment ensures low parasitic inductance and stable thermal performance under high di/dt (200 A/µs) and dv/dt (1000 V/µs) stress.

The module integrates two inverse-parallel thyristors in a single industrial-standard package with electrically isolated AlN ceramic baseplate. It supports natural or forced cooling configurations, with validated thermal transient impedance data (ZthJC) provided for sinusoidal and rectangular current waveforms across conduction angles from 30° to 180°.

FAQ

What is the maximum allowable junction temperature for TZ600N14KOFHPSA1?

The maximum junction temperature (Tvj max) is 135°C, as specified in the datasheet's thermal properties table. This limit must be respected under all operating conditions-including surge events-to ensure device reliability and avoid irreversible degradation of the silicon die or pressure-contact interface.

Does TZ600N14KOFHPSA1 require external snubber circuits?

Yes-snubbers are required to limit dv/dt stress during turn-off. With a critical dv/dt rating of 1000 V/µs, the module demands RC snubbers sized to keep transient voltage rise below this threshold, especially in inductive load switching or line-commutated applications with fast voltage recovery.

Can TZ600N14KOFHPSA1 be used in single-phase applications?

Yes-it is commonly deployed in single-phase soft starters and phase-controlled rectifiers. Its dual anti-parallel SCR structure supports full-wave AC control; gate timing must be synchronized to the single-phase waveform, with firing angle adjusted between 0° and 180° per half-cycle.

What is the creepage distance and isolation voltage rating?

The creepage distance is 15 mm, and the isolation test voltage is 3.6 kV RMS for 1 second (per DIN EN 60747-5-1). This rating validates safe operation when mounted directly to grounded heatsinks in industrial enclosures with pollution degree 2 or lower.
