Infineon Technologies DD89N16KHPSA1

Overview

DD89N16KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 1600 V repetitive peak reverse voltage (VRRM), 89 A average on-state current (IFAVM) per arm at TC = 100°C, and 140 A RMS on-state current (IFRMSM). It features silicon die with AlN internal insulation, 0.215 °C/W junction-to-case thermal resistance per arm (DC), and is designed for high-reliability industrial AC/DC conversion in B2/B6 bridge configurations.

For engineers reviewing the DD89N16KHPSA1 datasheet, DD89N16KHPSA1 pinout, DD89N16KHPSA1 application, or DD89N16KHPSA1 equivalent, key selection criteria include verified VRRM/VRSM ratings, transient thermal impedance ZthJC data for forced/natural cooling, on-state voltage (vF ≤ 1.5 V @ 300 A), threshold voltage (V(TO) = 0.75 V), and pressure-contact mechanical mounting torque (4 Nm ±10% for terminals).

Technical Context

This dual-arm rectifier module implements two independent high-voltage, high-current diode paths in a single press-pack housing. Each arm supports 1600 V VRRM and delivers 89 A IFAVM under DC conduction at 100°C case temperature, with 2.4 kA non-repetitive surge current capability at maximum junction temperature.

Thermal performance is defined by analytical transient thermal impedance models (ZthJC) for both DC and sinusoidal (180°) conduction, alongside case-to-heatsink resistance (RthCH ≤ 0.10 °C/W per arm), enabling precise thermal design for natural or forced-air-cooled systems using KM14 heatsinks.

Key Specifications

Pinout & Package

DD89N16KHPSA1 uses a press-pack module package with two isolated diode arms sharing a common baseplate. Mechanical mounting employs M1 screws (4 Nm ±15%) for case attachment and M2 terminals (4 Nm ±10%) for anode/cathode connections. Internal Si die use AlN ceramic insulation and pressure-contact metallization.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) for continuous operation is +150°C, aligned with the device's maximum junction temperature (Tvj max = 150°C) and specified thermal resistance (RthJC = 0.215 °C/W per arm). Derating curves in the datasheet define IFAVM vs. TC, confirming 89 A is valid only at TC ≤ 100°C; operation at 150°C requires current reduction to ~45 A per arm.

Does DD89N16KHPSA1 require external snubbers in B6 bridge operation?

Snubbers are recommended due to measured recovered charge (Qr) dependence on -di/dt, especially above 200 A/µs. The datasheet provides Qr vs. -di/dt curves for Tvj max and vRM = 0.8 VRRM, enabling calculation of required snubber capacitance and resistance to limit voltage overshoot during commutation in 50–400 Hz industrial rectifiers.

Can this module be used in parallel configurations?

Parallel operation is feasible with matched modules and balanced busbar layout, but not recommended without active current-sharing control. The 2.3 mΩ slope resistance (rT) and 0.75 V threshold voltage (V(TO)) create inherent current imbalance above 150 A total per arm; parallel use requires individual thermal monitoring and forced-air cooling uniformity to avoid thermal runaway.

What is the creepage distance and why does it matter for safety certification?

The creepage distance is 15 mm, measured across the insulated baseplate surface between terminals. This value satisfies IEC 60664-1 requirements for Pollution Degree 2 and 1600 V working voltage, enabling compliance with EN 50178 and UL 508 for industrial power converters operating in non-condensing indoor environments with moderate dust exposure.
