Infineon Technologies TZ810N22KOFHPSA2

Overview

TZ810N22KOFHPSA2 from Infineon Technologies is a pressure-contact thyristor module for phase-controlled AC power regulation, rated at 2200 V repetitive peak off-state voltage (VDRM/VRRM), 867 A average on-state current (ITAVM) at TC = 85°C, and 39 kA non-repetitive surge current (ITSM). It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and is designed for high-reliability industrial rectification and crowbar protection in drive systems.

For engineers reviewing the TZ810N22KOFHPSA2 datasheet, TZ810N22KOFHPSA2 pinout, TZ810N22KOFHPSA2 application, or TZ810N22KOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.0376 K/W), threshold voltage (0.82 V), slope resistance (0.17 mΩ), critical dv/dt rating (1000 V/µs), and gate trigger current (≤250 mA).

Technical Context

This double-sided, press-pack thyristor module implements phase-angle control in medium-power AC-DC conversion circuits. Its pressure-contact construction eliminates wire bonds and solder joints, enabling robust operation under high di/dt (200 A/µs) and dv/dt (1000 V/µs) stress, with commutated turn-off time of 240 µs at full-rated current.

The module integrates two anti-parallel thyristor dies in a single 70 mm baseplate package with basic insulation (IEC 61140 Class 1) and creepage distance of 36 mm. Thermal performance is optimized for forced-air or liquid-cooled heatsinks via low RthCH (0.012 K/W with TIM) and DC-rated ITAVM up to 867 A.

FAQ

What is the maximum junction temperature and how does it affect thermal design?

The maximum junction temperature (Tvj max) is 125°C. This limit governs allowable power dissipation: with RthJC = 0.0376 K/W, the module can dissipate up to 1940 W before reaching thermal shutdown. Designers must ensure heatsink interface resistance (RthCH) and ambient temperature keep case temperature below 100°C at full ITAVM to maintain safety margin.

Does TZ810N22KOFHPSA2 require external snubbers in typical drive applications?

Snubbers are not mandatory due to its 1000 V/µs critical dv/dt rating, but are recommended for systems with high stray inductance (>1 µH) or rapid line transients. The module's 240 µs commutated turn-off time and 200 A/µs diT/dt rating allow stable operation without snubbers in well-damped three-phase rectifiers with standard line reactors.

How is gate drive isolation implemented and what are the drive requirements?

Gate terminals (G1/K1G, G2/K2G) are galvanically isolated from main terminals and baseplate. Each gate requires ≤250 mA trigger current and ≤2 V trigger voltage at 25°C, with non-trigger current limited to 10 mA at full VDRM. Isolated gate drivers with ≥5 kV isolation and 1 A peak output are recommended for noise immunity in industrial environments.

Can TZ810N22KOFHPSA2 be used in six-pulse bridge configurations?

Yes-it is explicitly rated for B6 six-pulse bridge operation, supporting up to 2500 A output current with RthCA = 0.05 K/W. The datasheet provides ID vs. Ptot curves for both B2 and B6 topologies, confirming thermal viability when heatsink design meets specified RthCH and ambient limits.
