Infineon Technologies ETT510N16P60HPSA1

Overview

ETT510N16P60HPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 1600 V repetitive peak off-state voltage (VDRM/VRRM), 515 A average on-state current at TC = 85°C, and 15.3 kA non-repetitive surge current (ITSM), with electrically insulated base plate and pressure-contact die attachment for thermal and mechanical robustness - deployed in soft starters and static power controllers.

For engineers reviewing the ETT510N16P60HPSA1 datasheet, ETT510N16P60HPSA1 pinout, ETT510N16P60HPSA1 application, or ETT510N16P60HPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0729 K/W), critical dv/dt rating (1000 V/µs), gate trigger characteristics (IGT ≤ 250 mA), and isolation test voltage (3.0 kV RMS), all validated for crowbar, UPS rectifier, and bypass switch designs requiring high reliability under cyclic thermal stress.

Technical Context

This dual-thyristor phase-control module operates in anti-parallel configuration for full-wave AC control, supporting conduction angles from 30° to 180° in sinusoidal and rectangular current waveforms. Its pressure-contact construction eliminates wire bonds and solder layers, enabling stable RthJC (0.0365–0.076 K/W) and low parasitic inductance for fast commutation.

The device integrates two identical thyristor arms sharing a common insulated copper base plate (60 mm × 124 mm), rated for 135°C maximum junction temperature and 3.6 kV isolation (1 sec). Gate triggering is optimized for standard pulse transformers (vG ≤ 2 V, iG ≤ 250 mA), with critical di/dt (200 A/µs) and dv/dt (1000 V/µs) thresholds ensuring noise-immune turn-on in noisy industrial environments.

Key Specifications

Pinout & Package

ETT510N16P60HPSA1 is housed in an industrial-standard press-pack module with electrically insulated aluminum nitride (AlN) base plate (60 mm × 124 mm), M10 mounting holes, and screw-type terminals (M2, 12 Nm torque). The module contains two thyristor arms sharing common cathode/anode terminals and isolated gate connections.

FAQ

What is the maximum allowable case temperature for continuous operation?

The ETT510N16P60HPSA1 supports continuous operation with case temperature (TC) up to +85°C for rated ITAVM = 515 A. Its maximum junction temperature is 135°C, and thermal derating curves show usable current down to 0 A at TC = 135°C. Operation above 85°C requires strict adherence to the ITAVM vs. TC graph on page 7 of the technical information document.

Does this module require external snubbers in typical soft starter applications?

No external snubbers are required if the circuit's dv/dt remains below 1000 V/µs and di/dt stays under 200 A/µs - conditions met in most 50/60 Hz soft starter designs with standard line inductance. However, snubbers are recommended for high-frequency PWM-fed inverters or systems with long cable runs introducing reflected waves.

How is gate triggering synchronized in a three-phase B6 rectifier using two modules?

Each ETT510N16P60HPSA1 module controls one phase leg (two arms). Gate pulses are timed 60° apart across six total pulses per AC cycle, derived from phase-shifted zero-crossing detection. The 4 µs maximum gate delay (tgd) and 1 µs pulse width tolerance enable precise firing angle control within ±0.5° accuracy at 50 Hz.

Can the insulated base plate be directly mounted to a chassis-grounded heatsink?

Yes - the AlN-insulated base plate is rated for 3.0 kV RMS (1 minute) and 3.6 kV RMS (1 second) isolation, satisfying IEC 61140 Class 1 requirements. Direct mounting to grounded heatsinks is permitted without additional insulating pads, provided mechanical torque does not exceed 6 Nm for M10 screws and surface flatness remains within 0.05 mm.
