Infineon Technologies DD160N22KHPSA2

Overview

DD160N22KHPSA2 from Semikron is a press-pack dual-diode rectifier module rated for 2200 V repetitive peak reverse voltage, 270 A RMS on-state current, and 160 A average forward current at 100°C case temperature, designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.

For engineers reviewing the DD160N22KHPSA2 datasheet, DD160N22KHPSA2 pinout, DD160N22KHPSA2 application, or DD160N22KHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.130 °C/W per module), surge current capability (5.3 kA @ 10 ms), threshold voltage (0.8 V), slope resistance (1.0 mΩ), and isolation test voltage (3.0 kV RMS).

Technical Context

This dual-arm press-pack diode module integrates two independent silicon rectifier elements with AlN ceramic internal insulation and pressure-contact construction, enabling high-current conduction without wire bonds. Each arm supports full-cycle conduction angles up to 180° sine and handles DC, rec60°, rec120°, and rec180° waveforms.

Thermal performance is defined by transient junction-to-case impedance (Z_thJC) with analytical R-τ network parameters, and case-to-heatsink resistance (0.03 °C/W per module) under forced cooling. It operates within -40°C to +150°C case temperature range and requires M1 mechanical mounting torque of 6 Nm ±15%.

FAQ

What is the maximum allowable junction temperature for DD160N22KHPSA2?

The maximum junction temperature (Tvj max) is 150°C, as specified in the datasheet's thermal properties table. This limit applies under all operating conditions including surge events and defines the upper boundary for thermal design. Exceeding this value risks irreversible degradation of the silicon die and AlN insulation integrity.

Does DD160N22KHPSA2 require external snubbers?

Snubbers are recommended due to its recovered charge (Qr = 105.8 kA²s at Tvj max) and reverse recovery behavior under high di/dt. The datasheet provides Qr vs. -di/dt curves and suggests RC snubbers for B6 bridges operating above 200 A to limit voltage overshoot and EMI generation.

Can DD160N22KHPSA2 be paralleled with other modules?

Parallel operation is feasible only with matched modules and symmetrical busbar layout, as the device lacks integrated current-sharing features. Thermal coupling and inductance balancing are mandatory; the datasheet specifies ≤0.03 °C/W RthCH variation across modules to maintain <5% current imbalance at full load.

What is the creepage distance and why does it matter for this module?

The creepage distance is 15 mm, measured across the AlN-insulated surface between terminals and case. This value satisfies reinforced insulation requirements per IEC 61800-5-1 and UL 1741 SC for 2200 V systems, ensuring safe operation in humid or contaminated environments without tracking or flashover.
