Infineon Technologies ETD420N22P60HPSA1

Overview

ETD420N22P60HPSA1 from Infineon Technologies is a pressure-contact thyristor module for phase-controlled AC power regulation, featuring 2200 V repetitive peak off-state voltage (VDRM/VRRM), 427 A average on-state current at TC = 85°C (ITAVM), and 13.4 kA non-repetitive surge current (ITSM). It integrates dual thyristor arms in an industrial-standard 60 mm baseplate package with electrically insulated AlN substrate, used in soft starters and static power controllers for motor drives.

For engineers reviewing the ETD420N22P60HPSA1 datasheet, ETD420N22P60HPSA1 pinout, ETD420N22P60HPSA1 application, or ETD420N22P60HPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0795 K/W), critical dv/dt rating (1000 V/µs), gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 2.2 V), and isolation test voltage (3.6 kV for 1 sec).

Technical Context

This double-sided, dual-arm thyristor module employs pressure-contact die attachment and Advanced Medium Power Technology (AMPT) to ensure stable conduction under high di/dt (150 A/µs) and high dv/dt stress. Its electrically insulated baseplate enables direct mounting onto heatsinks without additional isolation hardware.

The device supports full-wave phase control in B2 (two-pulse) and B6 (six-pulse) bridge configurations, with commutated turn-off time (tq) of 280 µs at Tvj = 135°C and rated for continuous operation up to 135°C junction temperature.

FAQ

What is the maximum allowable case temperature for continuous operation?

The ETD420N22P60HPSA1 is rated for continuous operation up to 135°C case temperature (Tc op), matching its maximum junction temperature (Tvj max = 135°C) due to the low RthJC of 0.0795 K/W. Operation beyond this requires active derating per the ITAVM vs. TC curves in the datasheet, especially at conduction angles below 180°.

Can this module be used in a single-phase full-wave rectifier configuration?

Yes-ETD420N22P60HPSA1 supports single-phase full-wave rectification using its dual-arm structure in a B2 (two-pulse) bridge. Each arm handles one half-cycle, with gate terminals G1 and G2 independently controllable to achieve adjustable DC output voltage and regenerative capability when paired with appropriate snubbers and freewheeling paths.

Is the baseplate electrically isolated, and what is its isolation rating?

Yes-the baseplate is electrically insulated using aluminum nitride (AlN) ceramic with basic insulation per IEC 61140 Class 1. It achieves 3.6 kV RMS isolation for 1 second at 50 Hz, verified per the datasheet's VISOL specification, enabling safe use in grounded and floating heatsink configurations without additional isolation hardware.

What gate drive requirements must be met to ensure reliable triggering?

A minimum gate trigger current of 250 mA (IGT max) and voltage of 2.2 V (VGT max) at 25°C and 12 V anode-cathode voltage is required. Gate pulses must deliver ≥1 A peak current with diG/dt ≥1 A/µs for latching, and pulse width should exceed 20 µs (IL max = 1500 mA) to guarantee turn-on under worst-case junction temperature and voltage conditions.
